Such diagrams are well-known in the context of many-body perturbation theory, but their usefulness extends to theories such as coupled cluster as well. However, the Goldstone diagrams are more numerous than their Brandow or Hugenholtz counterparts due to a lack of antisymmetry in the orbital quantities, and the resultant equations can always be factorized into a more efficient form. Here we present a new diagrammatic interpretation for closed-shell orbital theories that starts directly from the original Brandow diagrams. The resulting equations are in terms of orbital quantities, but are based on ``spin-summed'' amplitudes and integrals, allowing them to be cast into an efficient and factorized form from the start. The derivation of the new diagrammatic formulation proceeds directly from the usual spin-orbital diagrammatic rules. A discussion of the differences between the spin-orbital and traditional Goldstone forms is given, along with several illustrative examples of the new diagrammatics.}, author = {Devin A.

At the heart of these developments there are latest-generation models based on Density Functional Theory for the proper treatment of stereo-electronic effects, coupled to the polarizable continuum model to deal with bulk solvent effects, and low-order perturbative treatments of anharmonic effects. Continuing our efforts to increase the range of application of virtual spectrometers, we report here about chiroptical spectroscopies with special reference to optical rotation and vibrational circular dichroism. The capabilities and possible limitations of our latest tool will be analyzed for the specific case of (S)-nicotine in vacuo and in different solvents.

Symmetry-adapted valence internal coordinates are employed to describe large-amplitude deformations from the ground-state equilibrium geometry. Both in-plane and out-of-plane deformations have systematically been explored. Four coordinates are identified as particularly effective in inducing a crossing of the 11Bu and 21Ag surfaces: two totally symmetric coordinates (symmetric C--C double-bond stretching and symmetric C--C--C bending) as well as the conrotatory and disrotatory torsions of the terminal CH2 groups. A single coordinate of bu symmetry is found to be active as 11Bu--21Ag coupling mode. On the basis of these ab initio results, a simple five-mode vibronic coupling model of the 11Bu--21Ag conical intersection is proposed.}, author = {Bojana Ostoji{\'c} and Wolfgang Domcke}, date-added = {2021-09-13 16:40:52 +0200}, date-modified = {2021-09-13 16:41:36 +0200}, doi = {https://doi.org/10.1016/S0301-0104(01)00373-1}, issn = {0301-0104}, journal = {Chem.

Compared to its popular predecessor GMTKN30 [Goerigk and Grimme J. Chem. Theory Comput.{,} 2011{,} 7{,} 291]{,} it allows assessment across a larger variety of chemical problems---with 13 new benchmark sets being presented for the first time---and it also provides reference values of significantly higher quality for most sets. GMTKN55 comprises 1505 relative energies based on 2462 single-point calculations and it is accessible to the user community via a dedicated website. Herein{,} we demonstrate the importance of better reference values{,} and we re-emphasise the need for London-dispersion corrections in density functional theory (DFT) treatments of thermochemical problems{,} including Minnesota methods. We assessed 217 variations of dispersion-corrected and -uncorrected density functional approximations{,} and carried out a detailed analysis of 83 of them to identify robust and reliable approaches. Double-hybrid functionals are the most reliable approaches for thermochemistry and noncovalent interactions{,} and they should be used whenever technically feasible. These are{,} in particular{,} DSD-BLYP-D3(BJ){,} DSD-PBEP86-D3(BJ){,} and B2GPPLYP-D3(BJ). The best hybrids are ωB97X-V{,} M052X-D3(0){,} and ωB97X-D3{,} but we also recommend PW6B95-D3(BJ) as the best conventional global hybrid. At the meta-generalised-gradient (meta-GGA) level{,} the SCAN-D3(BJ) method can be recommended. Other meta-GGAs are outperformed by the GGA functionals revPBE-D3(BJ){,} B97-D3(BJ){,} and OLYP-D3(BJ). We note that many popular methods{,} such as B3LYP{,} are not part of our recommendations. In fact{,} with our results we hope to inspire a change in the user community{'}s perception of common DFT methods.

In comparison with the parent tetraarylo-pyrrolo[3,2-b]pyrroles and benzo-fused pyrrolopyrroles, these new dyes showed moderately redshifted absorption. Almost all derivatives showed positive fluorescence solvatochromism and, for the first time, red-emitting pyrrolopyrroles were obtained. Computational studies revealed that, in most cases, there is negligible change in the geometry between ground and excited states. Interestingly, there was a fundamental difference between pyrrolopyrroles possessing electron-withdrawing substituents at positions 2 and 5 and their analogs lacking these substituents. The former dyes behaved like dipolar chromophores with the lowest excited state both one-photon and two-photon allowed, which corresponds to intramolecular charge transfer occurring along the branches perpendicular to the pyrrolopyrrole long axis. In compounds lacking electron-withdrawing substituents at positions 2 and 5, intramolecular charge transfer took place along the long axis of pyrrolopyrrole and consequently the one-photon transitions are not two-photon allowed. Despite displaying quadrupolar core-to-peripheral intramolecular charge transfer, these derivatives showed two-photon absorption cross sections in the NIR1 region comparable to tetraaryl-pyrrolo[3,2-b]pyrroles lacking π-expansion (up to about 500 GM).}, author = {Tasior, Mariusz and Clermont, Guillaume and Blanchard-Desce, Mireille and Jacquemin, Denis and Gryko, Daniel T.}, date-added = {2021-08-24 09:06:40 +0200}, date-modified = {2021-08-24 09:06:55 +0200}, doi = {https://doi.org/10.1002/chem.201804325}, eprint = {https://chemistry-europe.onlinelibrary.wiley.com/doi/pdf/10.1002/chem.201804325}, journal = {Chem.

Previous limitations of both air stability and electrical performance are now being overcome with a range of both small molecule and polymer-based solution-processable materials, which achieve charge carrier mobilities in excess of 0.5 cm2 V−1 s−1, a benchmark value for amorphous silicon semiconductors.

Due to the breadth of their utility, there have been several focused reviews on this topic since 1988. Considering the growing importance of these dyes, this review describes the overall progress made in four decades in both synthesis and the elucidation of their reactivity, and offers a critical comparison of various methods reported in the literature. The relationship between their structure and optical properties is also reviewed in detail. The extension of diketopyrrolopyrroles' chromophore leads to a significant change in both linear and nonlinear optical properties. A very strong bathochromic shift in the absorption and an increase in the two-photon absorption cross-section are typical for these analogues. Straightforward synthesis combined with good stability and a near-unity fluorescence quantum yield ensures that diketopyrrolopyrroles will continue to attract attention for years to come. The goal of this review is to systematize knowledge on these dyes, enabling their use in more real-world applications.}, author = {Grzybowski, Marek and Gryko, Daniel T.}, date-added = {2021-08-20 15:26:34 +0200}, date-modified = {2021-08-20 15:26:59 +0200}, doi = {https://doi.org/10.1002/adom.201400559}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/adom.201400559}, journal = {Adv.

Absorption spectra have been obtained in polar and nonpolar solvents at room temperature and in an EPA rigid glass at 77 K. The complete loss of resolution of the first singlet absorption in ethanol at room temperature is explained in terms of the formation of weak solute solvent complexes. This solvent effect is taken as evidence that the heterocyclic ring portion of the molecule is involved in the electronic transition. Fluorescence and phosphorescence emission spectra have been obtained in polar, nonpolar, and heavy atom rigid glasses at 77 K. Triplet decay lifetimes have been obtained both by directly measuring the phosphorescence decay and by monitoring the decay of triplet-triplet (T-T) absorption. The T-T absorption spectrum of BTD-d4 has been obtained in EPA rigid glass at 77 K in the regions from 20 000 cm−1 to 28 000 cm−1. The deuterium effect on the triplet state lifetime and the external heavy atom effect on phosphorescence intensity are interpreted as providing evidence for ππ∗ character in the lowest triplet state. On the other hand, the phosphorescence energy and the triplet lifetime are interpreted as providing evidence for nπ∗ character in the same state. Similary, the T-T spectrum is suggestive of nπ∗-ππ∗ interaction in the triplet manifold. A difference in the triplet state lifetime obtained by the two measurement techniques is discussed.}, author = {Bryan R. Henry and James D.

This is consistent with the observed [2] contraction of the molecule about the long in-plane axis in the excited state and with the fact that the corresponding electronic systems in 2,1,3-benzoselenadiazole and benzofurazan are dominated by a vibration which also has a wavenumber of about 500 cm−1.

We compare with the parent (B2-PLYP, B2GP-PLYP, PBE0-DH, and PBE-QIDH) and other (DSD-PBEP86) double-hybrid models as well as with some of the most widely employed hybrid functionals (B3LYP, PBE0, M06-2X, and ωB97X). For this purpose, we select a number of medium-sized intra- and inter-molecular charge-transfer excitations, which are known to be challenging to calculate using time-dependent density-functional theory (TD-DFT) and for which accurate reference values are available. We assess whether the high accuracy shown by the newest double-hybrid models is also confirmed for those cases too. We find that asymptotically corrected double-hybrid models yield a superior performance, especially for the inter-molecular charge-transfer excitation energies, as compared to standard double-hybrid models.

In many applications the size of the systems involved calls for time-dependent density functional theory (TDDFT) to be used in their computational modeling, due to its unprecedented balance between accuracy and efficiency. However, although exact in principle, in practise approximations must be made for the exchange-correlation functional in this theory, and the standard functional approximations perform poorly for excitations which have a long-range charge-transfer component. Intense progress has been made in developing more sophisticated functionals for this problem, which we review. We point out an essential difference between the properties of the exchange-correlation kernel needed for an accurate description of charge-transfer between open-shell fragments and between closed-shell fragments. We then turn to charge-transfer dynamics, which, in contrast to the excitation problem, is a highly non-equilibrium, non-perturbative, process involving a transfer of one full electron in space. This turns out to be a much more challenging problem for TDDFT functionals. We describe dynamical step and peak features in the exact functional evolving over time, that are missing in the functionals currently used. The latter underestimate the amount of charge transferred and manifest a spurious shift in the charge transfer resonance position. We discuss some explicit examples.}, author = {Neepa T Maitra}, date-added = {2021-02-24 13:08:34 +0100}, date-modified = {2021-02-24 13:08:34 +0100}, doi = {10.1088/1361-648x/aa836e}, journal = {Journal of Physics: Condensed Matter}, month = {sep}, number = {42}, pages = {423001}, publisher = {{IOP} Publishing}, title = {Charge Transfer in Time-Dependent Density Functional Theory}, url = {https://doi.org/10.1088/1361-648x/aa836e}, volume = {29}, year = 2017, bdsk-url-1 = {https://doi.org/10.1088/1361-648x/aa836e}} @article{Hue20, annote = {doi: 10.1021/acs.jctc.0c00296}, author = {Huet, L{\'e}on and Perfetto, Anna and Muniz-Miranda, Francesco and Campetella, Marco and Adamo, Carlo and Ciofini, Ilaria}, booktitle = {Journal of Chemical Theory and Computation}, da = {2020/07/14}, date = {2020/07/14}, date-added = {2021-02-24 13:03:46 +0100}, date-modified = {2021-02-24 13:03:57 +0100}, doi = {10.1021/acs.jctc.0c00296}, isbn = {1549-9618}, journal = {J.

It is definitely proven that the critical IPEA parameter used in CASPT2 calculations of ΔHelec, a key parameter in the design of SCO compounds, should be modified with respect to its default value of 0.25 a.u. and increased up to 0.50 a.u. The satisfactory agreement observed previously in the literature might result from an error cancellation originated in the default IPEA, which overestimates the stability of the HS state, and the erroneous atomic orbital basis set contraction of carbon atoms, which stabilizes the LS states. {\copyright} 2015 Wiley Periodicals, Inc.}, author = {Vela, Sergi and Fumanal, Maria and Ribas-Ari{\~n}o, Jordi and Robert, Vincent}, date-added = {2021-01-27 18:09:25 +0100}, date-modified = {2021-01-27 18:10:14 +0100}, doi = {https://doi.org/10.1002/jcc.24283}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/jcc.24283}, journal = {J.

Prominent features like doubly excited local and excimer states{,} accessible in multi-photon processes{,} as well as charge-transfer states arise naturally through the fully quantum-mechanical description of the aggregates. In this contribution the SOS//QM/MM approach is extended to simulate time-resolved 2D spectra that can be used to characterize ultrafast excited state relaxation dynamics with atomistic details. We demonstrate how critical structures on the excited state potential energy surface{,} obtained through state-of-the-art quantum chemical computations{,} can be used as snapshots of the excited state relaxation dynamics to generate spectral fingerprints for different de-excitation channels. The approach is based on high-level multi-configurational wavefunction methods combined with non-linear response theory and incorporates the effects of the solvent/environment through hybrid quantum mechanics/molecular mechanics (QM/MM) techniques. Specifically{,} the protocol makes use of the second-order Perturbation Theory (CASPT2) on top of Complete Active Space Self Consistent Field (CASSCF) strategy to compute the high-lying excited states that can be accessed in different 2D experimental setups.

To obtain a reliable potential energy profile along the deactivation pathways{,} the MS-CASPT2 method is employed even for the optimization of minimum energy structures in the excited state and conical intersection (CI) structures between the ground and excited states. In the imino (imino-keto) form{,} we locate a new CI structure involving the twisting of the imino group{,} and the decay pathway leading to this CI is found to be barrierless{,} suggesting a remarkably efficient deactivation of imino cytosine. In the keto (amino-keto) form{,} the MS-CASPT2 calculations exhibit an efficient decay path to the ethylene-like CI involving the twisting of the C--C double bond in the six-membered ring{,} with a barrier of ∼0.08 eV from the minimum of the 1ππ* state.

The goal of our study is to establish the mechanistic factors that make the primary phototautomerization step irreversible. Similar to what we recently described for ortho-nitrobenzaldehyde (NBA) (Migani et al.{,} Chem. Commun.{,} 2011{,} 47{,} 6383--6385){,} the IESHT in OPA is characterized by the relocation of two electrons from the in-plane to the out-of-plane orbital system. Consistent with this{,} OPA has the same IESHT mechanism as NBA. The first step of ketene formation is the hydrogen transfer{,} which starts on an (n{,} π*) state. The reaction coordinate goes through a conical intersection with the ground state and leads to a biradical intermediate with a bent ketene moiety. The second step is the linearization of the ketene moiety{,} which is associated to a change in the electronic configuration from biradical to ketene. Because of the electron relocation{,} the reverse transfer is similar to a Woodward--Hoffmann forbidden process with a sizeable barrier. This makes the tautomerization irreversible and allows the ketene to react further to biphthalide and benzaldehyde. Together with our previous NBA study{,} we establish the electronic relocation mechanism as a new mechanism for IESHT. This mechanism explains the different reactivity of OPA and NBA compared to organic photoprotectors{,} where the IESHT is reversed on a very short time scale.}, author = {Li, Quansong and Migani, Annapaola and Blancafort, Llu{\'\i}s}, date-added = {2021-01-27 16:20:50 +0100}, date-modified = {2021-01-27 16:21:29 +0100}, doi = {10.1039/C2CP40359E}, issue = {18}, journal = {Phys.

Since the first applications in spectroscopy were performed at the beginning of the present decade, the CASSCF/CASPT2 method has been used to study electronic spectra of a large number of compounds. The experience gained from this global investigation is illustrated in the present contribution through several examples. In most cases, the CASSCF reference function does characterize with sufficient accuracy the states of interest, which supports the use of a single reference perturbation theory in spectroscopic studies of organic systems. The CASSCF/CASPT2 method is capable of yielding accurate results for relative energies and other properties of excited states, provided that flexible one-electron basis sets are used and an appropriate active space can be chosen. The overall accuracy of the approach is high. The excitation energies are usually found to be within $\pm$0.2 eV of the available experimental energies for correctly assigned transitions. The review covers some of the most recent applications in the spectroscopy of organic compounds: absorption spectrum of free base porphin employing an extended treatment; vertical, nonvertical, and emission energies of long polyenals; spectra of trans- and cis-stilbene together with an analysis of certain static aspects of the photo-induced isomerization process; absorption spectra of purine DNA base monomers and related compounds, and analysis of the spectroscopic features of polypeptides based on intra- and interpeptide charge transfer transitions. In addition, the electronic spectra of organic compounds with interacting double bonds are rationalized. These studies either confirm existing experimental assignments or lead to new predictions and a novel understanding of the electronic spectra of the corresponding organic molecules. }, author = {Merchan, Manuela and Serrano-Andr\'{e}s,Luis and Roos, Bjorn O?}, booktitle = {Recent Advances in Multireference Methods}, date-added = {2021-01-27 08:59:32 +0100}, date-modified = {2021-01-27 09:00:55 +0100}, doi = {10.1142/9789812812186_0006}, eprint = {https://www.worldscientific.com/doi/pdf/10.1142/9789812812186_0006}, pages = {161--195}, publisher = {World Scientific}, series = {Recent Advances in Computational Chemistry}, title = {Multiconfigurational Perturbation Theory Applied to Excited States of Organic Compounds}, url = {https://www.worldscientific.com/doi/abs/10.1142/9789812812186_0006}, year = {1999}, bdsk-url-1 = {https://www.worldscientific.com/doi/abs/10.1142/9789812812186_0006}, bdsk-url-2 = {https://doi.org/10.1142/9789812812186_0006}} @article{Ser05, abstract = {The present contribution contains an overview of quantum-chemical methods and strategies to compute and interpret spectroscopic and photochemical phenomena in molecular systems.

The error in the heat of reaction for a number of isogyric reaction (no difference in number of pairs) varies between −2.5 and +1.0 kcal/mol. The same type of accuracy is obtained in calculations for excited states. The molecules B2, C2, FO, FOO, and FOOF have also been studied. Results for the first three molecules are in accordance with those of the benchmark molecules. The FO bond distance in FOO is predicted to be 0.02 {\AA} longer than experiment. The heat of formation for FOO is computed to be 2.9 kcal/mol with an uncertainty of $\pm$3 kcal/mol. Preliminary results for FOOF (obtained with a smaller basis set) indicate that the approach yields a somewhat too long FO bond distance (1.64 {\AA} compared to 1.58 {\AA} experimentally). {\copyright} 1993 John Wiley \& Sons, Inc.}, author = {Andersson, Kerstin and Roos, Bj{\"o}rn O.}, date-added = {2021-01-26 15:56:12 +0100}, date-modified = {2021-01-26 15:56:45 +0100}, doi = {https://doi.org/10.1002/qua.560450610}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/qua.560450610}, journal = {Int.

The methods yield energies, which are accurate to at least 0.2 eV, except in a few cases, where the CASSCF reference function does not characterize the electronic state with sufficient accuracy. The applications comprise: the polyenes from ethene to octatetraene (cis- and trans-forms); a number of cyclic pentadienes; norbornadiene; benzene, phenol, phosphabenzene, and the azabenzenes; free base porphin; and the nucleic acid base monomers cytosine, uracil, thymine, and guanine. Finally, the photochemistry of the molecules aminobenzonitrile (ABN) and dimethylaminobenzonitrile (DMABN) has also been studied, in particular the double fluorescence that occurs in DMABN. Taken together these studies comprise large amounts of new spectroscopic data of high accuracy, which either confirm existing assignments of experimental data or lead to new predictions and qualitative as well as quantitative understanding of a large number of electronic spectra. Most studies are restricted to ground state geometries (vertical energies), but in a few cases (octatetraene, ABN, and DMABN) also excited state geometries have been determined, thus yielding 0-0 transition energies and emission spectroscopic data.}, address = {Dordrecht}, author = {Roos, Bj{\"o}rn O. and F{\"u}lscher, Markus and Malmqvist, Per-{\AA}ke and Merch{\'a}n, Manuela and Serrano-Andr{\'e}s, Luis}, booktitle = {Quantum Mechanical Electronic Structure Calculations with Chemical Accuracy}, date-added = {2021-01-26 15:44:21 +0100}, date-modified = {2021-01-27 18:14:26 +0100}, doi = {10.1007/978-94-011-0193-6_8}, isbn = {978-94-011-0193-6}, pages = {357--438}, publisher = {Springer Netherlands}, title = {Theoretical Studies of the Electronic Spectra of Organic Molecules}, url = {https://doi.org/10.1007/978-94-011-0193-6_8}, year = {1995}, bdsk-url-1 = {https://doi.org/10.1007/978-94-011-0193-6_8}} @article{And94, abstract = {The potential energy curve of the Cr2 ground state has been obtained by multiconfigurational second-order perturbation theory.

With a time-dependent access to the many-body perturbation and coupled-cluster theories, it is shown how one can extract the regular part of the wave-operator which consists of linked cluster-operators only in the adiabatic limit. The procedure naturally suggests a hierarchy of lower valence model spaces P(k). once a particular m-valence incomplete model space P(m) is specified. The wave-operator Ω and the effective Hamiltonian Heff are linked in this development and are valence-universal in the sense of being valid for all P(k)' s. 0 ⩽ k ⩽ m. We have derived two distinct forms for Ω: (i) Ω = {exp(S)}, with { } as normal order with respect to suitable vacuum, where S are open operators inducing transitions from P(m) to outside it; (ii) ΩN = {exp(S + X)}, where X are additional closed operators which are introduced to maintain isometry of ΩN: P(k)ΩN + ΩN P(k) = P(k). In neither of these choices do we have intermediate normalization. It is also possible to develop an alternative strategy with the complete model spaces, such that an effective valence-universal operator H may be found which generates roots, only a subset of which are equal to the eigenvalues of H. These subsets are the ones that Heff would have furnished. This may thus be viewed as a Fock-space realization of the intermediate Hamiltonian approach.}, author = {Mukherjee, Debashis}, date-added = {2021-01-26 14:43:02 +0100}, date-modified = {2021-01-26 14:43:24 +0100}, doi = {https://doi.org/10.1002/qua.560300737}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/qua.560300737}, journal = {Int.

This chapter discusses the BW theory in detail and reviews the linked-cluster expansion for closed-shell systems. The essential ingredients of the linked-cluster result are: (1) the use of diagrams, (2) the RS form of perturbation theory, (3) the factorization theorem, and (4) ignoring the exclusion principle in intermediate states. The various formulations of the independent-pair approximation illustrate the fact that the appropriate ``leading cluster approximation'' can usually be derived and expressed equally well from several different viewpoints. The factorization theorem can be exploited to simplify the RS diagrams containing more than one open linked part. The extension of the Brueckner-Goldstone formalism to open-shell systems is discussed. As a specific application of the open-shell formalism, the chapter discusses how it can be used to resolve a specific many-body problem in the theory of magnetic insulator materials.}, author = {B.H.

Detailed vibrational analyses are given for BTD imbedded in napthalene and DCB. The polarization measurements show that the S1 state has B2 symmetry, like its selenium analogue (BSD). The transition is dominated by a single totally symmetric mode - 484 cm−1. The Herzberg-Teller coupling contributes only a very small fraction of the total intensity. The Stark measurements of a DCB sample containing both BTD and BSD enabled us to compare the charge distribution of BTD and BSD in the state S1. The Stark splittings of BTD are 17% greater than the splittings of BSD. Reorganization of the σ-core during the excitation is used to explain the difference. The drastic change in dipole moment upon excitation implies that the S1←S0 transitions of BTD and BSD are not localized in the six-membered ring as suggested by previous workers. Weak phosphorescence of BTD in napthalene and DCB and singlet-triplet absorption spectrum of neat BTD have been observed. The heavy atom effect of spin-orbit coupling is to explain the ST absorption intensity of BTD and BSD.}, author = {Tien-Sung Lin and James R.

This approach allows the exploration of the excited state potential energy surface of solvated molecules for the evaluation of minima and other stationary points, at a computational cost virtually identical to that of gas-phase LR-CCSD. The method is applied to the evaluation of vertical absorption and emission energies of 4-(N,N)-dimethyl-aminobenzonitrile (DMABN) in gas phase, cyclohexane, and acetonitrile solutions. The method is able to find the minima for the locally excited and charge transfer states, which are responsible for the dual-fluorescence of this compound.

These suggestions made us to revise our previous study on the photophysics of ABN and dimethyl-ABN (DMABN){,} based on the analysis of the potential energy surfaces of the low-lying excited states by means of ab initio calculations{,} using the CASSCF/CASPT2 protocol. We have first focused our attention to ABN. We have found that the (π--σ*) excited state can be in fact an intermediary state in the path to populate the ICT bright state{,} although its involvement in the process is not very probable. Our results suggest that the ICT most stable species is the twisted ICT(TICT) and that the partially twisted ICT minimum found in previous studies could be an artefact of the computational method. We have also found that radiationless deactivation is a competitive reaction that must be taken into account to explain the fluorescence patterns of these systems. To confirm our theories{,} we have also studied other systems with a similar architecture but with a very different luminescence behaviour: dimethyl-ABN{,} and the 2{,}3{,}4{,}5-tetrafluoro derivatives of ABN and DMABN (ABN-4F and DMABN-4F). The extension of the work and the different approaches in the study of the parent system and of the derivatives make the division of the work in two parts advisable. Part I collects the characterization of the minima and reaction paths connecting the critical points of the potential energy surfaces of the states involved in the ICT reaction of ABN. We have obtained{,} for the first time{,} the pathways of radiationless deactivation for this compound. We have also computed transition energies from the excited minima{,} to interpret the excited state absorption (ESA) spectra obtained experimentally. This information helps in the elucidation of the mechanism of ICT. In Part II we show an analoguous study for DMABN and ABN-4F and DMABN-4F and analyse and compare these results and those of Part I to explain different luminescence behaviours of the four systems studied.}, author = {Segado, Mireia and G{\'o}mez, Isabel and Reguero, Mar}, date-added = {2021-01-19 16:07:49 +0100}, date-modified = {2021-01-19 21:27:02 +0100}, doi = {10.1039/C5CP04690D}, issue = {9}, journal = {Phys.

Electronic excited states of nitrobenzene are mainly classified as local excitations within the benzene ring or nitro group and charge transfer excitations between the benzene and nitro group, with some transitions showing percentage from both. The nature of molecular orbitals, their orderings and energies are obtained from density functional theory calculations which help in assigning partially assigned/unassigned features in earlier photoelectron spectroscopy studies. Optimized geometry of ionic nitrobenzene predicts redistribution of charge density in the benzene ring rather than the nitro group resulting in stabilization of the benzene ring π orbitals in comparison to the neutral molecule. Time dependent density functional theory computations are found to describe the experimental spectra well with respect to energies, relative intensities and nature of the observed transitions in terms of valence, Rydberg or charge transfer type. New insights into the interpretation of 1B2u←1A1g and 1B1u←1A1g shifted benzene transitions in light of the present computational calculations are presented. The first few members of the ns, np and nd type Rydberg series in nitrobenzene, converging to the first six ionization potentials, identified in the spectra as weak but sharp peaks are reported for the first time. In general, transitions to the lowest three unoccupied molecular orbitals 4b1, 3a2 and 5b1 are valence or charge transfer in nature, while excitations to higher orbitals are predominantly Rydberg in nature. This work presents a consolidated experimental study and theoretical interpretation of the electronic absorption spectrum of nitrobenzene.}, author = {Sunanda Krishnakumar and Asim Kumar Das and Param Jeet Singh and Aparna Shastri and B.N.

This mechanism involves internal conversion (IC) and inter-system crossing (ISC) along three dominating internal coordinates of the nitro group and consistently explains the experimental findings. Relaxation from the lowest triplet state via ISC occurs along the out-of-plane bending coordinate of the nitro group{,} while initial IC as well as ultrafast ISC into the triplet manifold take place along symmetric NO stretching and ONO bending modes that have not been considered yet.

Furthermore, it was found that the 193-mμ band is composed of two bands, one of which is accompanied by vibrational structure. By combining these experimental results with a theoretical consideration, the most reliable assignments of the absorption bands of nitrobenzene have been accomplished. The results show that the 240-mμ band can be assigned to the intramolecular charge-transfer band. This assignment was also supported by the fact that the band decreases its intensity to a great extent in nitromesitylene. Furthermore, the present study concluded that there is the 6% contribution of the charge-transfer structure in the ground state of nitrobenzene, although some doubt had been thrown about the existence of the resonance interaction in view of the fact that the x-ray crystal analysis data show no shrinkage of the CN bond length.}, author = {Saburo Nagakura and Maomi Kojima and Yasuko Maruyama}, date-added = {2021-01-07 15:09:15 +0100}, date-modified = {2021-01-07 15:09:37 +0100}, doi = {https://doi.org/10.1016/0022-2852(64)90066-9}, issn = {0022-2852}, journal = {J.

We outline the basics of a CC response theory framework that allows the transfer of the attractive accuracy and convergence properties associated with CC methods over to the calculation of electronic excitation energies and properties. Key factors affecting the accuracy of CC excitation energy calculations are discussed as are some of the key CC models in this field. To aid both the practitioner as well as the developer of CC excited state methods, we also briefly discuss the key computational steps in a working CC response implementation. Approaches aimed at extending the application range of CC excited state methods either in terms of molecular size and phenomena or in terms of environment (solution and proteins) are also discussed. {\copyright} 2011 John Wiley \& Sons, Ltd.

The conventional metric of success for new functionals has been the accuracy of their calculated energies. Medvedev et al. examined how well these functionals calculate electron density across a series of neutral and cationic atoms (see the Perspective by Hammes-Schiffer). Although historically the accuracies of energy and density have improved in tandem, certain recent functionals have sacrificed fidelity to the true density.Science, this issue p. 49; see also p. 28The theorems at the core of density functional theory (DFT) state that the energy of a many-electron system in its ground state is fully defined by its electron density distribution. This connection is made via the exact functional for the energy, which minimizes at the exact density. For years, DFT development focused on energies, implicitly assuming that functionals producing better energies become better approximations of the exact functional. We examined the other side of the coin: the energy-minimizing electron densities for atomic species, as produced by 128 historical and modern DFT functionals. We found that these densities became closer to the exact ones, reflecting theoretical advances, until the early 2000s, when this trend was reversed by unconstrained functionals sacrificing physical rigor for the flexibility of empirical fitting.}, author = {Medvedev, Michael G. and Bushmarinov, Ivan S. and Sun, Jianwei and Perdew, John P. and Lyssenko, Konstantin A.}, date-added = {2020-10-21 14:05:32 +0200}, date-modified = {2020-10-21 14:05:53 +0200}, doi = {10.1126/science.aah5975}, eprint = {https://science.sciencemag.org/content/355/6320/49.full.pdf}, issn = {0036-8075}, journal = {Science}, number = {6320}, pages = {49--52}, publisher = {American Association for the Advancement of Science}, title = {Density Functional Theory is Straying From the Path Toward the Exact Functional}, url = {https://science.sciencemag.org/content/355/6320/49}, volume = {355}, year = {2017}, bdsk-url-1 = {https://science.sciencemag.org/content/355/6320/49}, bdsk-url-2 = {https://doi.org/10.1126/science.aah5975}} @article{Chr21, author = {Chrayteh, A. and Blondel, Aymeric and Loos, Pierre-Francois and Jacquemin, Denis}, date-added = {2020-10-21 10:46:30 +0200}, date-modified = {2021-01-11 12:44:55 +0100}, journal = {J.

The TCE-generated renormalized and active-space CC computer codes are parallel and applicable to closed- and open-shell references, enabling accurate calculations of potential energy surfaces along bond-breaking coordinates and excited states displaying a significant multi-reference character. The effectiveness of the new codes in describing electronic quasi-degeneracies is illustrated by the renormalized CC calculations of the potential energy curve of HCl and the active-space CC calculations for the low-lying excited states of the Be3 system. {\copyright} 2005 Wiley Periodicals, Inc.

The variational criteria for the quasienergy determines the time-evolution of the wave-function parameters and the time-averaged time-dependent Hellmann--Feynman theorem allows an identification of response functions as derivatives of the quasienergy. The quasienergy therefore plays the same role as the usual energy in time-independent theory, and the same techniques can be used to obtain computationally tractable expressions for response properties, as for energy derivatives in time-independent theory. This includes the use of the variational Lagrangian technique for obtaining expressions for molecular properties in accord with the 2n+1 and 2n+2 rules. The derivation of frequency-dependent response properties becomes a simple extension of variational perturbation theory to a Fourier component variational perturbation theory. The generality and simplicity of this approach are illustrated by derivation of linear and higher-order response functions for both exact and approximate wave functions and for both variational and nonvariational wave functions. Examples of approximate models discussed in this article are coupled-cluster, self-consistent field, and second-order M{\o}ller--Plesset perturbation theory. A discussion of symmetry properties of the response functions and their relation to molecular properties is also given, with special attention to the calculation of transition- and excited-state properties. {\copyright} 1998 John Wiley \& Sons, Inc.

The comparison of the theoretically predicted rotational constants and fundamental frequencies for silylidene (SiCH2) with existing experimental observations shows excellent agreement. The CH2 (CD2) rocking modes (ν6) are the most anharmonic among the six vibrational modes, consistent with limited experimental observations. The five stationary point structures and their relative energies on the ground state potential energy surface (PES) are accurately determined using the focal point extrapolation technique.

Membrane protein levels differ from one type of cell to another{,} and the expression of membrane proteins also changes from normal to diseased cells. For example{,} prostate cancer cells have been reported to have downregulated expression of membrane proteins{,} including zinc transporters{,} compared with normal prostate cells. These reports inspired us to design a fluorescence probe sensitive to protein α-helical structures to discriminate individual prostate cancer cells from normal ones. A benzazole derivative (1 in this study) was observed to emit strong fluorescence resulting from an excited-state intramolecular proton transfer (ESIPT) in protein α-helical environments. The intensity of ESIPT fluorescence of 1 was observed to be positively correlated with the α-helix content of proteins. The molecular docking simulation suggested that it had low energy for the binding of 1 to proteins when the binding sites were localized within the α-helical regions of protein via H-bonds. Furthermore{,} 1 was found to be localized in cell membranes through binding to transmembrane α-helical regions of membrane proteins{,} and was capable of probing differences in the α-helix contents of membrane proteins between normal and cancerous prostate cells through changes in the ESIPT emission intensity. These results indicated that 1 could distinguish individual prostate cancer cells from normal ones{,} as the changes in the ESIPT fluorescence intensity of 1 could reflect the regulation in expression of the membrane proteins including zinc transporters.

However, excited states have been nearly excluded from the this approach since most accurate QFFs are based on the ``gold standard'' coupled cluster singles, doubles, and perturbative triples [CCSD(T)] method which is not readily extended to excited states. In this work, rovibronic spectroscopic data is provided for the isoformyl radical, a molecule of significance in combustion and astrochemistry, both through the traditional means of variational access to excited states with CCSD(T) and in the novel extension of QFFs routinely to treat electronically excited states through the standard coupled cluster excited state approach, equation of motion (EOM) CCSD. It is shown here that the new EOM-based QFF provides structural parameters and rotational constants that are quite close to those from a related CCSD(T)-based QFF for the 1 2A″ excited state of HOC. The anharmonic vibrational frequency percent differences between the two QFFs are less than 0.4% for the O--H stretch, less than 1.9% for the C--O stretch, and around 3.0% for the bend. Even so, the pure excited state EOM-QFF anharmonic frequencies are still very good abinitio representations that may be applied to systems where electronically excited states are not variationally accessible.

The calculations have been performed using the complete active space self-consistent field (CASSCF) method followed by the valence internally contracted multireference configuration interaction (MRCI) approach in combination with the correlation-consistent basis sets of Dunning and co-workers. The effects on the PECs by the core--valence correlation and relativistic corrections are taken into account. The way to consider the relativistic correction is to use the second-order Douglas--Kroll Hamiltonian approximation. The core--valence correlation correction calculations are performed with the cc-pCVQZ basis set. The relativistic correction is carried out at the level of cc-pV5Z basis set. In order to obtain more reliable results, the PECs determined by the MRCI calculations are also corrected for size-extensivity errors by means of the Davidson modification (MRCI+Q). The PECs are extrapolated to the complete basis set (CBS) limit by the total-energy extrapolation scheme. With these PECs, the spectroscopic parameters (Te, Re, ωe, ωexe, ωeуe, Be, αe and γe) are determined and compared with those reported in the literature. Finally, with the PECs obtained by the MRCI+Q/CV+DK+Q5 calculations, the complete vibrational states are computed for the eight electronic states by solving the ro-vibrational Schr{\"o}dinger equation for the non-rotating radical, and the vibrational levels and inertial rotation and centrifugal distortion constants of the first 11 vibrational states are reported, which agree favorably with the available experimental data.

In the structural calculations of C2H3, the optimized geometry and vibrational frequencies of X2A′, the vertical electronic transition energies (A2A″ ← X2A′ and B2A′ ← X2A′), the vertical ionization potential and the permanent dipole moment of X2A′ have been computed. The harmonic vibrational frequencies and infrared intensities of C2H3X2A′ obtained from this calculation will help the spectroscopic observation for the vibrational modes, most of which are unobserved. The calculated vertical transition energy, 25529 cm−1 for A2A″ ← A2A′, and the vertical ionization potential, 8.33 eV from an MRCI method with atomic natural orbitals, are in excellent agreement with the experimental values of 24815 cm−1 and 8.25 eV, respectively. The vertical transition of B2A′ ← X2A′, predicted to be 43910 cm−1 from this work, will facilitate the experimental search for the undiscovered B̄ state of C2H3 through spectroscopic observation. In calculating the intramolecular rearrangement in C2H3X2A′, using CCSD(T)/Dunning's triple zeta polarizations, the non-classical structure with a hydrogen atom bridged between the CC bond has been found to lie at least 47 kcal/mol above the classical equilibrium structure. The calculation also indicates that the non-classical C2H3X2A′ is an unstable isomer, corresponding to a transition state. The computed barrier for the tunnelling of α-H in C2H3X2A′ is also in excellent agreement with the upper bound limit of < 1500 cm−1. determined from high-resolution infrared spectroscopy. The dissociation energy of C2H3 → C2H2 + H and the energy difference between the isomers of acetylene and vinylidene, calculated in the present study, are also consistent with experimental measurements.}, author = {Jeng-Han Wang and Hung-Chang Chang and Yit-Tsong Chen}, date-added = {2020-01-21 18:35:32 +0100}, date-modified = {2020-01-21 18:36:15 +0100}, doi = {https://doi.org/10.1016/0301-0104(95)00441-6}, issn = {0301-0104}, journal = {Chem.

A basis set of valence atomic natural orbitals has been augmented with a series of Rydberg orbitals that have been generated as centered onto the Be atom. The resulting basis set can be described as 4s2p1d/2s1p (Be/H) + 4s4p3d. It allows to calculate Rydberg states up to n= {3,4,5} of the s, p, and d series of Rydberg states. The FCI vertical ionization potential for the same basis set and geometry amounts to 8.298 eV. Other properties such as FCI electric dipole and quadrupole moments and FCI transition dipole and quadrupole moments have also been calculated. The results provide a set of benchmark values for energies, wave functions, properties, and transition properties for the five electron BeH molecule. Most of the states have large multiconfigurational character in spite of their essentially single excited nature and a number of them present an important Rydberg-valence mixing that is achieved through the mixed nature of the particle MO of the single excitations. {\copyright} 2007 Wiley Periodicals, Inc.

The observed spectra were assigned to c-type transitions with ΔKa = $\pm$1 and also to axis-switching transitions with ΔKa = 0 or −2, but all with K′a = 0, both for HC35Cl and HC37Cl. A rotational analysis yielded the rotational constants and quartic centrifugal distortion constants for the ground vibronic state and the band origin. A weak vibronic band, about one-third as intense as the main band, was found at about 57 cm−1 to the violet of the main band for both isotopic species, and was ascribed to a transition from the ground vibronic state to a vibrational level, possibly (041), of the {\~A} state. The rotational levels of HC35Cl in the {\~A} state showed a large perturbation; the J′ = 8, 9, and 10 levels were found to be split into two components. A normal coordinate analysis was carried out to calculate the centrifugal distortion constants and the inertia defect, which were in fair agreement with the observed values. The molecular structure of HCCl in the ground vibronic state was recalculated from the rotational constants of the two isotopic species combined with the 0.75B0 + 0.25C0 value previously reported for DC35Cl.}, author = {Masao Kakimoto and Shuji Saito and Eizi Hirota}, date-added = {2020-01-08 20:11:45 +0100}, date-modified = {2020-01-08 20:12:05 +0100}, doi = {https://doi.org/10.1016/0022-2852(83)90345-4}, issn = {0022-2852}, journal = {J.

Equilibrium geometries and vibrational frequencies of the three electronic states, adiabatic transition energy of the first excited singlet state, as well as the ground singlet---lowest triplet energy gap (S-T gap) of each of FCX carbenes have been obtained. Effects of the basis set of icMRCI+Q calculation on the geometries and energies have been investigated. In addition, various corrections, including the scalar relativistic effect, spin-orbit coupling, and core-valence correlation, have been studied in calculating the transition energies and the S-T gaps, especially for heavy-atom carbenes. This results have been compared with previous calculations using a variety of methods. Our icMRCI+Q results are in very good agreement with the high-resolution laser-based spectroscopic results where available.

All geometries are fully optimized and compare favorably to previous theoretical and experimental values. The HCP molecule is predicted to be 85.4 kcal/mol lower in energy than its linear isomer at the-MP2/6-31G*//MP2/6-31G* level. The energy barrier for hydrogen rearrangement is found to be merely 2.3 kcal from the HPC end. CASSCF studies were initiated to clarify the low barrier and lent support to a flat surface as HPC converts to stable, linear HCP at the TZV + + ** level. CASSCF also predicts that HPC is unstable with respect to bending. Harmonic vibrational frequencies for HCP results in 5\% accuracy or better. A bent triplet is found to be the lowest excited state using the CASSCF method. {\copyright} 1993 John Wiley \& Sons, Inc.}, author = {Goldstein, Elisheva and Jin, Suqian and Carrillo, M.

Performance of this so-called MP2.5 (third-order scaling factor of 0.5) method has also been tested for 33 nucleic acid base pairs and two stacked conformers of porphine dimer. In all the test cases, performance of the MP2.5 method was shown to be superior to the scaled spin-component MP2 based methods, e.g. SCS--MP2, SCSN--MP2 and SCS(MI)--MP2. In particular, a very balanced treatment of hydrogen-bonded compared to stacked complexes is achieved with MP2.5. The main advantage of the approach is that it employs only a single empirical parameter and is thus biased by two rigorously defined, asymptotically correct ab-initio methods, MP2 and MP3.

The essential computational requisite is a Hermitean eigenvalue problem in the space of single and double excitations on the Hartree-Fock ground state. Spin-free decoupled ADC(2) working equations for the singlet-singlet and singlet-triplet transitions have been formulated and employed. As the only additional approximation, the mixing between configurations with a different number of excited core-level electrons has been neglected. The calculated excitation energies of both the core-valence and core-Rydberg transitions are in very good agreement with the experimental data and are distinctly improved with respect to previous theoretical work, including extended configuration interaction treatments.

We selected a small prototypical symmetric squaraine dye for which these accurate computations are feasible and experimental data are available. We show that while all methods reasonably reproduce the OPA spectrum, an acceptable description and assignment of the states responsible for TPA is only possible through ADC(3) and multireference calculations, due to the strong involvement of double-excitations. The nature of ground state and OPA and TPA states is investigated with a rigorous reading of the CASSCF wavefunctions in terms of localized molecular orbitals on the donor and acceptor fragments, showing that these states arise from a balance of many different contributions including biradical configurations, local excitations and charge-transfer states where both side aromatic rings and the carbonyls of the squarylium moiety act as donors.}, author = {Avila-Ferrer, Francisco J. and Angeli, Celestino and Cerezo, Javier and Coriani, Sonia and Ferretti, Alessandro and Santoro, Fabrizio}, date-added = {2019-11-01 17:31:50 +0100}, date-modified = {2019-11-16 17:30:53 +0100}, doi = {10.1002/cptc.201900121}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/cptc.201900121}, journal = {ChemPhotoChem}, keywords = {biradicaloid character, charge transfer, computational photochemistry, density functional calculations, vibronic spectra}, number = {9}, pages = {778--793}, title = {The Intriguing Case of the One-Photon and Two-Photon Absorption of a Prototypical Symmetric Squaraine: Comparison of TDDFT and Wave-Function Methods}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/cptc.201900121}, volume = {3}, year = {2019}, bdsk-url-1 = {https://onlinelibrary.wiley.com/doi/abs/10.1002/cptc.201900121}, bdsk-url-2 = {https://doi.org/10.1002/cptc.201900121}} @article{Tik19, abstract = {The electronic structure and optical properties of the isomeric difluoroboron β-diketonates, 2,2-difluoro-4-methylnaphtho-[2,1-e]-1,3,2-dioxaborin (I) and 2,2-difluoro-4-methylnaphtho-[1,2-e]-1,3,2-dioxaborin (II), were studied by means of X-ray photoelectron, absorption and luminescence spectroscopies.

The emergence of these effects is examined for PPV oligomers based on high level ab initio excited-state calculations. The computed many-body wavefunctions are subjected to our recently developed exciton analysis protocols to provide a qualitative and quantitative characterization of excitonic effects. The discussion is started by providing high-level benchmark calculations using the algebraic-diagrammatic construction for the polarization propagator in third order of perturbation theory (ADC(3)). These calculations support the general adequacy of the computationally more efficient ADC(2) method in the case of singly excited states but also reveal the existence of low-energy doubly excited states. In a next step{,} a series of oligomers with chains of two to eight phenyl rings is studied at the ADC(2) level showing that the confinement effects are dominant for small oligomers{,} while delocalized exciton bands emerge for larger systems. In the case of the largest oligomer{,} the first twenty singlet and triplet excited states are computed and a detailed analysis in terms of the Wannier and Frenkel models is presented. The presence of different Wannier bands becomes apparent{,} showing a general trend that exciton sizes are lowered with increasing quasi-momentum within the bands.}, author = {Mewes, Stefanie A. and Mewes, Jan-Michael and Dreuw, Andreas and Plasser, Felix}, date-added = {2019-11-01 17:16:49 +0100}, date-modified = {2019-11-01 17:17:10 +0100}, doi = {10.1039/C5CP07077E}, issue = {4}, journal = {Phys.

In contrast, the structure due to Rydberg excitations is weak, but series have been observed converging onto the or limits in pyrimidine and the or limits in pyrazine. A comparison between the photoabsorption spectrum of pyrazine-h4 and that for pyrazine-d4, together with calculated transition energies, has helped clarify the assignments of the 6ag→npb1u and npb2u Rydberg series. The vibrational progressions associated with these states have been assigned through analogy with those in the corresponding photoelectron band. The time-dependent version of density functional theory has been used to calculate oscillator strengths and excitation energies for the optically allowed singlet--singlet valence transitions, and also to obtain the excitation energies for electric-dipole-forbidden and/or spin-forbidden transitions. These theoretical results have allowed many of the experimentally observed bands to be assigned and provide a generally satisfactory description of the valence shell photoabsorption spectrum.

Many features of this complex and unusual spectrum, and its associated single vibronic level fluorescence spectrum, can be explained using a simple vibronic model.

Here, a new efficient code, SPOCK, is introduced that calculates spin-orbit matrix elements in the one-center mean-field approximation for multireference CI wave functions. For the first time, the computation of spin-dependent interactions within a Kohn-Sham orbital based CI (DFT/MRCI) scheme1 is made possible. The latter approach is suitable for large scale systems with up to 100--200 valence electrons. Test calculations are performed on well-known diatomic molecules and the thiocarbonyl pyranthione. Spin-orbit matrix elements show good agreement with their Hartree-Fock orbital based counterparts but are obtained at considerably lower expense, thus demonstrating the power of the method. As an application singlet-triplet couplings in thiophene are investigated that are important for the photophysics and photochemistry. Spin-orbit matrix elements between all π → π* excited states are found to be small. Considerably larger spin-orbit matrix elements are observed only for cases in which π → σ* excited configurations are involved. {\copyright} 2002 Wiley Periodicals, Inc.

Both valence excitations (π → π* and π → π*) and excitations to the lowest = 3{,} 4 Rydberg states are calculated. The dependency of vertical excitation energies on several factors are investigated{,} such as (i) the effect of different molecular geometries on the vertical excitation energies; (ii) the dependency of the predictions on various features of the basis set (diffuseness{,} cardinal number in the correlation consistent series{,} inclusion of molecule centered functions and the position of such); and (iii) the level of electron correlation model (studied by a hierarchy of CC methods: CCS{,} CC2{,} CCSD and triple corrected CCSD by means of CCSDR(3)). Geometrical relaxation and zero-point vibrational motion in the excited states are accounted for by explicit calculations for the valence states and indirectly through studying ionized states for the Rydberg states. Best estimates of vertical and 0-0 transition energies are given and compared to previous calculations and experiments. Excellent agreement with available experimental 0-0 energies is obtained. For the lowest excited state we question a structure recently derived from experimental data{,} and argue that reasonable agreement with experiment is obtained with our structure.}, author = {{\"O}hrn, Anders and Christiansen, Ove}, date-added = {2019-09-23 13:03:47 +0200}, date-modified = {2019-11-07 11:33:58 +0100}, doi = {10.1039/B007949I}, issue = {5}, journal = {Phys.

Quantum Monte Carlo (QMC) methods have been applied very successfully to ground state properties but still remain generally less effective than other non-stochastic methods for electronically excited states. Nonetheless, we have recently reported accurate excitation energies for small organic molecules at the fixed-node diffusion Monte Carlo (FN-DMC) within a Jastrow-free QMC protocol relying on a deterministic and systematic construction of nodal surfaces using the selected configuration interaction (sCI) algorithm known as CIPSI (Configuration Interaction using a Perturbative Selection made Iteratively). Albeit highly accurate, these all-electron calculations are computationally expensive due to the presence of core electrons. One very popular approach to remove these chemically-inert electrons from the QMC simulation is to introduce pseudopotentials (also known as effective core potentials). Taking the water molecule as an example, we investigate the influence of Burkatzki-Filippi-Dolg (BFD) pseudopotentials and their associated basis sets on vertical excitation energies obtained with sCI and FN-DMC methods. Although these pseudopotentials are known to be relatively safe for ground state properties, we evidence that special care may be required if one strives for highly accurate vertical transition energies. Indeed, comparing all-electron and valence-only calculations, we show that using pseudopotentials with the associated basis sets can induce differences of the order of 0.05 eV on the excitation energies. Fortunately, a reasonable estimate of this shift can be estimated at the sCI level.}, author = {Anthony Scemama and Michel Caffarel and Anouar Benali and Denis Jacquemin and Pierre-Fran{\c c}ois Loos}, date-added = {2019-09-07 12:10:14 +0200}, date-modified = {2019-09-07 12:10:35 +0200}, doi = {https://doi.org/10.1016/j.rechem.2019.100002}, issn = {2211-7156}, journal = {Res.

The aromaticity of each ring was probed using nucleus independent chemical shift (NICS) calculations. Molecular orbital analysis identified the substituent effects on the energy of the frontier orbitals. Calculations show that the ground state multiplicity can be effectively controlled with strategic substitutions. EWG directly attached on the negative cyanine of the central arene stabilize zwitterionic singlet states whereas EDG attached at the same position favor a triplet ground state.

We study methylenecyclopropene and acrolein in water by using several wavefunction approaches to validate the supermolecular reference and to assess their response to embedding. We find that quantum Monte Carlo, complete-active space second-order perturbation theory, and coupled cluster methods give very consistent solvatochromic shifts and a similar response to embedding. Our scheme corrects the excitation energies produced with a frozen environment, but the values are often overshot. To ameliorate the problem, one needs to use wavefunction densities to polarize the environment. The choice of the exchange-correlation functional in the construction of the potential has little effect on the excitation, whereas the approximate kinetic-energy functional appears to be the largest source of error.}, author = {Daday, Csaba and K{\"o}nig, Carolin and Neugebauer, Johannes and Filippi, Claudia}, date-added = {2019-07-15 10:25:45 +0200}, date-modified = {2019-07-15 10:25:53 +0200}, doi = {10.1002/cphc.201402459}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/cphc.201402459}, journal = {ChemPhysChem}, keywords = {density functional calculations, differential polarization effects, embedding, excited states, solvent effects}, number = {15}, pages = {3205--3217}, title = {Wavefunction in Density Functional Theory Embedding for Excited States: Which Wavefunctions, which Densities?}, url = {https://onlinelibrary.wiley.com/doi/abs/10.1002/cphc.201402459}, volume = {15}, year = {2014}, bdsk-url-1 = {https://onlinelibrary.wiley.com/doi/abs/10.1002/cphc.201402459}, bdsk-url-2 = {https://doi.org/10.1002/cphc.201402459}} @article{Bre72, author = {Breslow, Ronald and Oda, Masaji}, date-added = {2019-07-15 10:09:17 +0200}, date-modified = {2019-07-15 10:09:38 +0200}, doi = {10.1021/ja00768a089}, eprint = {https://doi.org/10.1021/ja00768a089}, journal = {J.

This work introduces a fast atom-pairwise dispersion correction, dDMC that is compatible with the most recent variant of self-consistent charge density functional tight binding (SCC-DFTB). The emphasis is placed on improving the description of π-π stacked motifs featuring sulfur-containing molecules that are known to be especially challenging for DFTB. Our scheme relies upon the use of Mulliken charges using minimal basis set that are readily available from the DFTB computations at no additional cost. The performance and efficiency of the dDMC correction are validated on examples targeting energies, geometries, and molecular dynamic trajectories. {\copyright} 2014 Wiley Periodicals, Inc.}, author = {Petraglia, Riccardo and Steinmann, Stephan N. and Corminboeuf, Clemence}, date-added = {2019-07-10 09:05:23 +0200}, date-modified = {2019-07-10 09:05:48 +0200}, doi = {10.1002/qua.24887}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/qua.24887}, journal = {Int.

In particular, two problems are frequently encountered: (a) the simultaneous presence of valence and Rydberg excited states in the same energy region can potentially lead to artificial valence--Rydberg mixing in the electronic wave functions. (b) Rydberg states have a tendency to be difficult to converge. We have implemented an approach for the consistent description of both valence and Rydberg excited states within the CASSCF electronic structure model. By employing the multiconfigurational second- and third-order perturbation theory (CASPT2/3) methods based on CASSCF reference wave functions, the procedure is verified by comparison with spectroscopic results for the example molecule pyrazine. Vertical excitation energies and other properties have been calculated for various electronic states. Basis sets and active spaces were selected to provide accurate results. Two combinations of aug-cc-pVTZ level basis sets complemented by Rydberg functions have been employed to calculate estimates for the properties of 19 singlet excited states of pyrazine. While many of the assignments made in previous studies could be confirmed, there are also several new aspects emerging from the present investigation.}, author = {Woywod, Clemens and Papp, Attila and Hal{\'a}sz, G{\'a}bor J. and Vib{\'o}k, {\'A}gnes}, date-added = {2019-06-14 14:38:04 +0200}, date-modified = {2019-11-07 11:31:51 +0100}, day = {01}, doi = {10.1007/s00214-009-0678-x}, issn = {1432-2234}, journal = {Theor.

The XMS-CASPT2 method is based on the extended multi-configuration quasi-degenerate perturbation theory proposed earlier by Granovsky [J. Chem. Phys.{,} 2011{,} 134{,} 214113]. We show that the conical intersection at the XMS-CASPT2 level can be described without artifacts if the entire method is invariant with respect to any unitary rotations of the reference functions. The photoabsorption spectra of the 11B3u and 11B2u states of pyrazine are simulated{,} based on a vibronic-coupling model Hamiltonian. The XMS-CASPT2 spectrum of the 11B3u band is found to be comparable to the one computed by a more expensive multireference configuration interaction (MRCI) method{,} while the XMS-CASPT2 simulation of the 11B2u band is slightly inferior to the MRCI one.}, author = {Shiozaki, Toru and Woywod, Clemens and Werner, Hans-Joachim}, date-added = {2019-06-14 14:30:46 +0200}, date-modified = {2019-06-14 14:32:48 +0200}, doi = {10.1039/C2CP43381H}, issue = {1}, journal = {Phys.

The primary purpose of these studies is to gain further experience with the STEOM-CCSD approach, and to gauge its accuracy. It is shown that the accuracy of the method exceeds the accuracy of EOM-CCSD, and that results for valence excited states are often close to EOM-CCSD(T̃). A number of low lying 0-0 transitions are determined in pyridine and the diazines. The geometries and vibrational frequencies of excited states are determined at the CI singles level, while final electronic energies are calculated through single point STEOM-CCSD. The manifold of excited states, ionized and electron attached states are analyzed as the geometries are distorted from the ground state equilibrium structures.}, author = {Marcel Nooijen}, date-added = {2019-06-14 10:32:07 +0200}, date-modified = {2019-11-07 11:31:05 +0100}, doi = {https://doi.org/10.1016/S1386-1425(98)00261-3}, issn = {1386-1425}, journal = {SpectroChim.

In addition to several broad bands due to transitions into valence states, the spectra exhibit numerous sharp bands associated with Rydberg states belonging to series converging onto the X̃2A2 or the {\~A}2B1 state limits. Vertical excitation energies and oscillator strengths have been computed using the second- and third-order algebraic-diagrammic construction polarisation propagator methods (ADC(2) and ADC(3)), and the equation-of-motion coupled-cluster method at the level of singles and doubles model (EOM-CCSD). Adiabatic excitation energies have been estimated using previously computed corrections. The theoretical predictions have allowed assignments to be proposed for the Rydberg series observed in the present single-photon absorption spectra and for some additional series, mainly of A2 symmetry, reported in previous multiphoton excitation studies. The assignments of some of the Rydberg series converging onto the {\~A}2B1 state limit have been revised and, guided by our calculations, the principal series is ascribed to the 2b1→nda2 1B2 and 2b1→ndb1 1A1 transitions. f-type Rydberg series, previously observed only in the multiphoton absorption spectrum of furan, have been observed and assigned. Such f-type series, converging onto either the X̃2A2 or the {\~A}2B1 state thresholds, contribute significantly to the single-photon absorption spectrum. Many of the absorption bands associated with Rydberg states display vibrational progressions which resemble those in the corresponding photoelectron band. It appears that some of the structure associated with the 1a2→3pb2 1B1 and 1a2→3pb1 1B2 transitions involves excitation of non-totally symmetric vibrational modes.}, author = {D.M.P. Holland and E.A.

For the first time the mechanism of excited-state intramolecular proton transfer and solvatochromic effect were in depth investigated based on time-dependent density functional theory methods in this research. Calculated absorption and emission spectra peaks were very agreement with the relative values that observed in experiment. Upon photo-excitation process the frontier molecular orbitals and charge-transfer excitation degree were portrayed and analyzed in different solvents, unraveling the solvatochromic effect on spectral properties. Optimal normal HBT-H, isomer HBT-T and anion HBT-A structures were calculated in different solvents, the decreasing order of intramolecular hydrogen bond strength (PhMe > CH3Cl > CH2Cl2 > ACN > DMF) under different solvents were obtained by comparing the bond parameters of hydrogen bond and corresponding infrared vibrational frequencies. More importantly, calculated Hirshfeld charges of donor and acceptor atoms essentially explained the effect of solvent polarities on excited-state intramolecular hydrogen-bond intensity. Because hydrogen bond interaction offered driving force for proton transfer reactions, the effect of solvent polarities on excited state intramolecular proton transfer reaction mechanism was further explained by calculating reactive activation energies.}, author = {Yunfan Yang and Yunpeng Chen and Yu Zhao and Wei Shi and Fengcai Ma and Yongqing Li}, date-added = {2018-12-10 16:30:30 +0100}, date-modified = {2018-12-10 16:30:43 +0100}, doi = {https://doi.org/10.1016/j.jlumin.2018.10.077}, issn = {0022-2313}, journal = {J.

Upon photoexcitation, these dyes exhibit intense dual fluorescence with contribution from the enol (E*) and the keto (K*) emission, with K* being formed through excited-state intramolecular proton transfer (ESIPT). We show that the ratio of emission intensity E*/K* can be fine-tuned by judiciously decorating the molecular core with electron-donating or -attracting substituents. Push--pull dyes 9 and 10 functionalized by a strong donor (nNBu2) and a strong acceptor group (CF3 and CN, respectively) exhibit intense dual emission, particularly in apolar solvents such as cyclohexane in which the maximum wavelength of the two bands is the more strongly separated. Moreover, all dyes exhibit strong solid-state dual emission in a KBr matrix and polymer films with enhanced quantum yields reaching up to 54 \%. A wise selection of substituents led to white emission both in solution and in the solid state. Finally, these experimental results were analyzed by time-dependent density functional theory (TD-DFT) calculations, which confirm that, on the one hand, only E* and K* emission are present (no rotamer) and, on the other hand, the relative free energies of the two tautomers in the excited state guide the ratio of the E*/K* emission intensities.}, author = {Benelhadj, Karima and Muzuzu, Wenziz and Massue, Julien and Retailleau, Pascal and Charaf-Eddin, Azzam and Laurent, Ad{\`e}le D. and Jacquemin, Denis and Ulrich, Gilles and Ziessel, Raymond}, date-added = {2018-11-19 17:53:08 +0100}, date-modified = {2021-04-14 16:14:14 +0200}, doi = {10.1002/chem.201402717}, eprint = {https://onlinelibrary.wiley.com/doi/pdf/10.1002/chem.201402717}, journal = {Chem.

However, aromaticity is not an unambiguous term; therefore, its definition is enumerative. The criteria are based on energy (increased stability), molecular geometry (very low bond lengths alternation), magnetism (induction of the diatropic ring current by external magnetic field) and reactivity (tendency to maintain $\pi$-electron structure in chemical reactions). The energetic criterion is based on resonance energy and aromatic stabilization energy, whereas harmonic oscillator model of aromaticity---on molecular geometry. Magnetism-based criteria are illustrated by local indicators (for individual rings): nucleus independent chemical shifts and proton nuclear magnetic resonance chemical shifts as well as the global aromaticity index---exaltation of the magnetic susceptibility. For selected homo- and hetero-cyclic compounds, illustrative data are presented in tables, which allow the comparison of the above-mentioned indices.

The model, called vertical electrostatic model 42 (VEM42), is based on representing the solute by a set of distributed atomic monopoles obtained by charge model 2 (CM2) and representing the solvent by its static and optical dielectric constants. The theory is applied here with intermediate neglect of differential overlap for spectroscopy--parameterization 2 (INDO/S2) configuration interaction wave functions. The model is implemented in the ZINDO electronic structure code package. We present illustrative applications to the singlet n→π* excitation of acetone in nine solvents. When the electrostatics are augmented by one‐parameter estimates of dispersion and hydrogen‐bonding contributions, the experimental solvatochromic shifts in the nine solvents are reproduced with a mean unsigned error of 65 cm--1 (0.2 kcal/mol). These calculations present a compelling picture of the quantitative origin of the solvatochromic red and blue shifts in this prototype n→π* excitation. {\copyright} 2000 John Wiley \& Sons, Inc.

For the 11B u state the configuration interaction (CI) wave function used for the computation of the respective density matrix contained all possible single and double excitations from the 1b g ($\pi$) orbital into all virtual orbitals and double excitations describing $\sigma$--$\pi$ electron correlation. For the ground and 21A g states a standard multireference (MR) CI with singles and doubles (CISD)/complete-active-space (CAS)(4,4) wave function was used. In the second step, these ANOs were used in extended MR-CISD, MR-CISD with Davidson correction and MR averaged quadratic coupled cluster calculations. This scheme was also extended to state-averaging including the four lowest Rydberg states 11B g (3s), 11A u (3p $\sigma$ ), 21A u (3p $\sigma$ ) and 21B u (3p $\pi$). Our best value for the vertical excitation energy to the 11B u state is 6.18 eV, close to previous equation-of-motion coupled-cluster with singles and doubles including noniterative triples [EOM - CCSD( )] and complete-active-space perturbation theory to second order (CASPT2) results, but significantly lower than most of the previous MR-CI and MR-CI based results. The computed vertical excitation energy to the 21A g state of 6.55 eV is significantly below previous EOM-CCSD(T) and EOM - CCSD( ) results and demonstrates the deficiencies of these methods in the case of MR situations. On the other hand, this excitation energy is larger than previous CASPT2 results for the 21A g state. The character of the 11B u state is predominantly of valence character, but is more diffuse than the ground state. values for the 11B u state range between 25.4 and 26.3a 0 2 in the three-state calculations.}, author = {Dallos, Michal and Lischka, Hans}, date-added = {2018-04-19 13:08:10 +0000}, date-modified = {2019-08-19 14:02:19 +0200}, day = {01}, doi = {10.1007/s00214-003-0557-9}, issn = {1432-2234}, journal = {Theor.

The semistochastic heat-bath configuration interaction (SHCI) algorithm, which efficiently and systematically approaches the full configuration interaction (FCI) limit, is used to provide close approximations to the FCI energies in these systems. This article presents the largest FCIlevel calculation to date on hexatriene, using a polarized double-$\zeta$ basis (ANO-L-pVDZ), which gives rise to a Hilbert space containing more than 1038 determinants. These calculations give vertical excitation energies of 5.58 and 5.59 eV, respectively, for the 21Ag and 11Bu states, showing that they are nearly degenerate. The same excitation energies in butadiene/ANO-L-pVDZ were found to be 6.58 and 6.45 eV. In addition to these benchmarks, our calculations strongly support the presence of a previously hypothesized ring-minimum species of ozone that lies 1.3 eV higher than the open-ring-minimum energy structure and is separated from it by a barrier of 1.11 eV.}, author = {Chien, Alan D. and Holmes, Adam A. and Otten, Matthew and Umrigar, C.

We present a general and efficient scheme that allows the treatment of a large number of Rydberg and valence states at the MR-CISD, MR-CISD+Q and MR-AQCC levels while using only a fraction of the size of the configuration space as compared to a full complete-active-space reference wave function. This scheme is applied to the calculation of vertical excitations and various avoided crossings between ten Rydberg and five valence singlet states of formaldehyde including transition dipole moments and oscillator strengths. Basis set effects, choice of configuration space and size-extensivity corrections have been considered. It is found that size-extensivity effects as computed by MR-CISD+Q and MR-AQCC play an important role especially for the description of the $\pi$$\pi$* state and for avoided crossings in which this state is involved.}, author = {M{\"u}ller, Thomas and Lischka, Hans}, date-added = {2018-03-02 21:05:08 +0000}, date-modified = {2018-03-02 21:05:25 +0000}, day = {01}, doi = {10.1007/s002140100286}, issn = {1432-2234}, journal = {Theor.

The chromenylium-based fluorophores were regarded as acceptor parts and the aniline served as donor parts; their pH-dependent fluorescent responses were used to evaluate the photoinduced electron transfer (PET) or intramolecular charge transfer (ICT) processes between the chromenylium-based fluorophores and aniline. Two chromenylium-indole hybrid functional dyes (1a-b) respectively showed a fluorescence enhancement and decrease with increasing acidity{,} while chromenylium-coumarin hybrid dye (1c) gave an OFF-ON response towards a gradually decreasing pH. The three dyes gave emissions at 675-850 nm when they were excited at 650 nm{,} and the calculated pKa values of 1a-c are 4.13{,} 3.15 and 2.48{,} respectively. The optical responses were also illustrated by (TD)DFT calculation; the OFF-ON emission of dye 1c was mainly controlled by the PET process{,} and both PET and ICT processes were found between the aniline parts and the chromenylium-indole parts in dyes 1a-b.}, author = {Xiao, Jin-Wei and Zhu, Wei-Jin and Sun, Ru and Xu, Yu-Jie and Ge, Jian-Feng}, date-added = {2018-03-02 08:06:04 +0000}, date-modified = {2018-03-02 08:06:14 +0000}, doi = {10.1039/C6RA19831G}, issue = {101}, journal = {RSC Adv.}, pages = {98985--98993}, publisher = {The Royal Society of Chemistry}, title = {Evaluation of electron or charge transfer processes between chromenylium-based fluorophores and protonated-deprotonated aniline}, url = {http://dx.doi.org/10.1039/C6RA19831G}, volume = {6}, year = {2016}, bdsk-url-1 = {http://dx.doi.org/10.1039/C6RA19831G}} @article{Che16, abstract = {Hydrogen sulfide (H2S) and sulfite (SO32-) are two important sulfur-containing species that play different and important roles in industrial and biological processes. Accordingly{,} the development of efficient methods for simple{,} rapid{,} sensitive and selective monitoring of H2S and SO32- is of the utmost importance in both environmental and biological sciences. In this study{,} we developed a new dual functional probe NIR-DNP for discriminative detection of H2S and SO32-. This probe can sense H2S and SO32- via two different approaches{,} a significant near-infrared fluorescence enhancement and color change from purple to cyan induced by H2S as well as a visible color change from purple to colorless caused by SO32-. The detection limits of the probe NIR-DNP for H2S and SO32- in aqueous solutions were 36.53 nM and 33.33 nM{,} respectively. Competitive experiments demonstrated that the probe NIR-DNP had a high fluorescence selectivity for H2S and excellent colorimetric selectivity for SO32- over other analytes. The sensing mechanism of the probe toward H2S and SO32- was based on the H2S-induced thiolysis of dinitrophenyl ether and SO32--induced nucleophilic addition{,} respectively. Further investigation showed that the probe NIR-DNP could be used to develop an easy-to-prepare and easy-to-detect paper-based test strip for cheap and effective detection of SO32-. Also{,} the probe NIR-DNP has the potential to image exogenous and endogenous H2S in living cells.}, author = {Chen, Sheng and Ma, Chao and Yuan, Mao-Sen and Wang, Wenji and Wang, Dong-En and Chen, Shu-Wei and Wang, Jinyi}, date-added = {2018-03-02 08:04:03 +0000}, date-modified = {2018-03-02 08:05:07 +0000}, doi = {10.1039/C6RA15065A}, issue = {88}, journal = {RSC Adv.}, pages = {85529--85537}, publisher = {The Royal Society of Chemistry}, title = {A dual functional probe: sensitive fluorescence response to H2S and colorimetric detection for SO32-}, url = {http://dx.doi.org/10.1039/C6RA15065A}, volume = {6}, year = {2016}, bdsk-url-1 = {http://dx.doi.org/10.1039/C6RA15065A}} @article{Zho17, author = {Zhou, Liyi and Wang, Qianqian and Tan, Yi and Lang, Matthew J. and Sun, Hongyan and Liu, Xiaogang}, date-added = {2018-03-02 07:58:37 +0000}, date-modified = {2018-03-02 07:58:45 +0000}, doi = {10.1002/chem.201701365}, issn = {1521-3765}, journal = {Chem.

In contradistinction to ``classical'' diagnostic imaging, it sets forth to probe the molecular abnormalities that are the basis of disease rather than to image the end effects of these molecular alterations. While the underlying biology represents a new arena for many radiologists, concomitant efforts such as development of novel agents, signal amplification strategies, and imaging technologies clearly dovetail with prior research efforts of our specialty. Radiologists will play a leading role in directing developments of this embryonic but burgeoning field. This article presents some recent developments in molecular sciences and medicine and shows how imaging can be used, at least experimentally, to assess specific molecular targets. In the future, specific imaging of such targets will allow earlier detection and characterization of disease, earlier and direct molecular assessment of treatment effects, and a more fundamental understanding of the disease process. }, author = {Ralph Weissleder and Umar Mahmood}, date-added = {2018-02-15 08:46:57 +0000}, date-modified = {2018-06-14 10:21:54 +0000}, doi = {10.1148/radiology.219.2.r01ma19316}, eprint = {https://doi.org/10.1148/radiology.219.2.r01ma19316}, journal = {Radiology}, number = {2}, pages = {316--333}, title = {Molecular Imaging}, url = {https://doi.org/10.1148/radiology.219.2.r01ma19316}, volume = {219}, year = {2001}, bdsk-url-1 = {https://doi.org/10.1148/radiology.219.2.r01ma19316}} @article{Ing07, author = {James Inglese and Ronald L.

To account for systematic errors found in the calculation of dissociation energies{,} an empirical correction applied to the zeroth-order Hamiltonian{,} called the IPEA shift{,} was introduced in 2004. The errors were attributed to an unbalanced description of open-shell versus closed-shell electronic states and is believed to also lead to an underestimation of excitation energies. Here we show that the use of the IPEA shift is not justified and the IPEA should not be used to calculate excited states{,} at least for organic chromophores. This conclusion is the result of three extensive analyses. Firstly{,} we survey the literature for excitation energies of organic molecules that have been calculated with the unmodified CASPT2 method. We find that the excitation energies of 356 reference values are negligibly underestimated by 0.02 eV. This value is an order of magnitude smaller than the expected error based on the calculation of dissociation energies. Secondly{,} we perform benchmark full configuration interaction calculations on 137 states of 13 di- and triatomic molecules and compare the results with CASPT2. Also in this case{,} the excited states are underestimated by only 0.05 eV. Finally{,} we perform CASPT2 calculations with different IPEA shift values on 309 excited states of 28 organic small and medium-sized organic chromophores. We demonstrate that the size of the IPEA correction scales with the amount of dynamical correlation energy (and thus with the size of the system){,} and gets immoderate already for the molecules considered here{,} leading to an overestimation of the excitation energies. It is also found that the IPEA correction strongly depends on the size of the basis set.

The low energy absorption band{,} assigned to the ([small pi]*) ? 7b2(nN) (11B1 ? 11A1) transition{,} at 3.85(4) eV and the vibrational progressions superimposed upon it have been observed for the first time{,} due to the availability of a high-resolution photon beam (0.075 nm){,} corresponding to 3 meV at the midpoint of the energy range studied. Vibronic coupling has been shown to play an important role dictating the nature of the observed excited states{,} especially for the lowest 1B1 state. The 21B1 state is proposed to have its origin at 7.026 eV according to the vibrational excitation reported in this energy region (7.8-8.4 eV). New experimental evidence of 41A1 state with a maximum cross section at 8.800 eV is supported by previous ab initio quantum chemical calculations. Rydberg series have been assigned converging to the three lowest ionisation energy limits{,} 9.32 eV (2B2){,} 10.41 eV (2B1) and 11.1 eV (2A1 + 2A2) with new members reported for the first time and classified according to the magnitude of the quantum defects ([small delta]).

The fission of a singlet to triplet in it has been expected to elevate the quantum efficiency of organic solar cells. However{,} the quantum efficiency is still very low and the fission process is still under debate. Controversies also exist on the energies of the singlet and triplet states in acene. Using the many-body Green{'}s function theory{,} which includes the GW method and Bethe-Salpeter equation (BSE){,} we compared the electronic excited states of several kinds of acene molecules (naphthalene to pentacene) at geometries optimized by different approaches. The energies of both the singlet and triplet depend strongly on the geometries of the molecules and their stacking. The non-negligible contribution from the resonant and anti-resonant transition coupling can cause large errors of the Tamm-Dancoff approximation{,} and the full BSE is required to get accurate results which are consistent with experiments. We found that accurate ionization energies and exciton energies can only be obtained when the geometries optimized by the Hartree-Fock approach are used. Singlet fission may be realized in isolated molecules{,} clusters{,} and surfaces{,} but it is hard in perfect pentacene crystals energetically.

PDT uses photosensitizers (PSs, non-toxic dyes) that are activated by absorption of visible light to initially form the excited singlet state, followed by transition to the long-lived excited triplet state. This triplet state can undergo photochemical reactions in the presence of oxygen to form reactive oxygen species (including singlet oxygen) that can destroy cancer cells, pathogenic microbes and unwanted tissue. The dual-specificity of PDT relies on accumulation of the PS in diseased tissue and also on localized light delivery. Tetrapyrrole structures such as porphyrins, chlorins, bacteriochlorins and phthalocyanines with appropriate functionalization have been widely investigated in PDT, and several compounds have received clinical approval. Other molecular structures including the synthetic dyes classes as phenothiazinium, squaraine and BODIPY (boron-dipyrromethene), transition metal complexes, and natural products such as hypericin, riboflavin and curcumin have been investigated. Targeted PDT uses PSs conjugated to antibodies, peptides, proteins and other ligands with specific cellular receptors. Nanotechnology has made a significant contribution to PDT, giving rise to approaches such as nanoparticle delivery, fullerene-based PSs, titania photocatalysis, and the use of upconverting nanoparticles to increase light penetration into tissue.

However, the intrinsic chemical instability and self-aggregation properties of \{NIR\} dyes in physiological condition limit their widely applications in the pre-clinic study in living animals. Squaraine dyes are among the most promising \{NIR\} fluorophores with high absorption coefficiencies, bright fluorescence and photostability. By introducing dicyanovinyl groups into conventional squaraine (SQ) skeleton. These acceptor-substituted \{SQ\} dyes not only show superior \{NIR\} fluorescence properties (longer wavelength, higher quantum yield) but also exhibit more chemical robustness. In this work, we demonstrated highly stable and biocompatible supramolecular adducts of \{SQ\} and the natural carrier protein, i.e., bovine serum albumin (BSA) (SQ⊂BSA) for tumor targeted imaging and photothermal therapy in vivo. \{SQ\} was selectively bound to \{BSA\} hydrophobic domain via hydrophobic and hydrogen bonding interactions with up to 80-fold enhanced fluorescence intensity. By covalently conjugating target ligands to BSA, the SQ⊂BSA was capable of targeting tumor sites and allowed for monitoring the time-dependent biodistribution of SQ⊂BSA, which consequently determined the protocol of photothermal therapy in vivo. We envision that this supramolecular strategy for selectively binding functional imaging agents and/or drugs into human serum albumin might potentially utilize in the preclinical and even clinic studies in the future. }, author = {Fu-Ping Gao and Yao-Xin Lin and Li-Li Li and Ya Liu and Ulrich Mayerh{\"o}ffer and Peter Spenst and Ji-Guo Su and Jing-Yuan Li and Frank W{\"u}rthner and Hao Wang}, date-added = {2016-10-02 17:14:00 +0000}, date-modified = {2016-10-08 17:40:47 +0000}, doi = {http://dx.doi.org/10.1016/j.biomaterials.2013.10.039}, issn = {0142-9612}, journal = {Biomaterials}, keywords = {Photothermal therapy}, number = {3}, pages = {1004--1014}, title = {Upramolecular Adducts of Squaraine and Protein for Non- Invasive Tumor Imaging and Photothermal Therapy in Vivo}, url = {http://www.sciencedirect.com/science/article/pii/S0142961213012696}, volume = {35}, year = {2014}, bdsk-url-1 = {http://www.sciencedirect.com/science/article/pii/S0142961213012696}, bdsk-url-2 = {http://dx.doi.org/10.1016/j.biomaterials.2013.10.039}} @article{Mor01, abstract = {An organic light-emitting diode (OLED) with a squarylium dye-doped aluminium quinoline (Alq3) emission layer prepared by vapor deposition method has a pure red emission.

Cancer \{NIR\} molecular imaging relies greatly on the development of stable, highly specific and sensitive molecular probes. Organic dyes have shown promising clinical implications as non-targeting agents for optical imaging in which indocyanine green has long been implemented in clinical use. Recently, significant progress has been made on the development of unique \{NIR\} dyes with tumor targeting properties. Current ongoing design strategies have overcome some of the limitations of conventional \{NIR\} organic dyes, such as poor hydrophilicity and photostability, low quantum yield, insufficient stability in biological system, low detection sensitivity, etc. This potential is further realized with the use of these \{NIR\} dyes or \{NIR\} dye-encapsulated nanoparticles by conjugation with tumor specific ligands (such as small molecules, peptides, proteins and antibodies) for tumor targeted imaging. Very recently, natively multifunctional \{NIR\} dyes that can preferentially accumulate in tumor cells without the need of chemical conjugation to tumor targeting ligands have been developed and these dyes have shown unique optical and pharmaceutical properties for biomedical imaging with superior signal-to-background contrast index. The main focus of this article is to provide a concise overview of newly developed \{NIR\} dyes and their potential applications in cancer targeting and imaging. The development of future multifunctional agents by combining targeting, imaging and even therapeutic routes will also be discussed. We believe these newly developed multifunctional \{NIR\} dyes will broaden current concept of tumor targeted imaging and hold promise to make an important contribution to the diagnosis and therapeutics for the treatment of cancer. }, author = {Shenglin Luo and Erlong Zhang and Yongping Su and Tianmin Cheng and Chunmeng Shi}, date-added = {2016-10-02 17:00:08 +0000}, date-modified = {2016-10-08 17:40:29 +0000}, doi = {http://dx.doi.org/10.1016/j.biomaterials.2011.06.024}, issn = {0142-9612}, journal = {Biomaterials}, keywords = {Multifunctional agents}, number = {29}, pages = {7127--7138}, title = {A Review of NIR Dyes in Cancer Targeting and Imaging}, url = {http://www.sciencedirect.com/science/article/pii/S0142961211006892}, volume = {32}, year = {2011}, bdsk-file-1 = {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}, bdsk-url-1 = {http://www.sciencedirect.com/science/article/pii/S0142961211006892}, bdsk-url-2 = {http://dx.doi.org/10.1016/j.biomaterials.2011.06.024}} @article{Sre08, abstract = {This feature article highlights the recent developments in the field of squaraine chemistry.

The selective detection of Hg2+ with the symmetrical-squaraine unit gave rise to a significant bathochromic shift toward the \{NIR\} region (λmax 697--840 nm in CH3CN). The absorption studies also indicate a high affinity of Hg2+ toward the formation of 2:1 complexes, which is in well understanding with the observational consequences. Fluorescence studies experimentally proved that only 640 nm absorption peak is responsible for the emission peak at 683 nm. A recognition mechanism based on the binding mode is proposed by means of absorption changes, 1H \{NMR\} titration experiments, FT-IR study and theoretical calculations. }, author = {Boddu Ananda Rao and Hyungjoo Kim and Young-A.

The interaction of these water soluble dyes with biological objects was studied. It was found, that the addition of enzyme gialuronidaze (64 units) to water solution of dye II, at constant concentration (2×10--6 M) of dye, leads to the drop of absorptive and fluorescent abilities of solution and to the broadening of absorption spectrum. The addition of this enzyme to water solution of dye \{III\} leads to the appearance of a new emission band at λmax=702 nm in fluorescence spectrum and to the intensification of emission on this band at further increase of enzyme concentration in the solution.

Congreve et al. (p. 334) have developed a method to harvest the excess energy in carbon-based absorbers through a process termed {\textquotedblleft}singlet fission.{\textquotedblright} In this process, high-energy photons propel two current carriers, rather than just one, by populating a singlet state that spontaneously divides into a pair of triplet states. Although it works in a functioning organic solar cell, the efficiency needs improving.Singlet exciton fission transforms a molecular singlet excited state into two triplet states, each with half the energy of the original singlet. In solar cells, it could potentially double the photocurrent from high-energy photons. We demonstrate organic solar cells that exploit singlet exciton fission in pentacene to generate more than one electron per incident photon in a portion of the visible spectrum. Using a fullerene acceptor, a poly(3-hexylthiophene) exciton confinement layer, and a conventional optical trapping scheme, we show a peak external quantum efficiency of (109 {\textpm} 1)\% at wavelength λ = 670 nanometers for a 15-nanometer-thick pentacene film. The corresponding internal quantum efficiency is (160 {\textpm} 10)\%.

The origin band of acrolein is predissociated to the extent that the J-atructure is so much broadened as to be unobserved. From the rotational structure which is observed, it can be deduced that an increase of 3$\,^{\circ}$ in the ∠CCC and ∠CCO is most likely to occur in the excited state. In the vibrational structure, four members of a progression m a vibration with a frequency of about 1270 cm--1 are active. This vibration has long been attributed to a CO stretching mode and an increase of the CO and C=C bond lengths by 0̃·1 {\AA} coupled with a similar decrease in the C-C bond length is proposed to account for this progression, the strong activity of the CC stretching mode and the change in IA. Another weaker electronic system whose origin band is at about 4059 {\AA} has been photographed. The bands are probably hybrids with the transition moment in the plane of the molecule.

Less fluorescence quantum efficiencies and short fluorescence lifetime in the solid state are the shortcomings of the existing ESIPT solid state emitters. Designing of ESIPT chromophores with high fluorescence quantum efficiencies and a long fluorescence lifetime in the solid state is a challenging issue because of the unclear mechanism of the solid state emitters in the excited state.

In dry, non-polar solvents,only a single fluorescence band is observed, in the blue---green range, and is attributed to the tautomer produced by the shift of a hydrogen atom along the intramolecular hydrogen bond joining the phenolic oxygen and the imino N atom. In weak hydrogen-bonding solvents an additional UV (approximately 350 nm) band can be detected in both families of dyes. This is due to a small fraction of ground state open-enol form, which does not yield the excited state phototautomerization because the intramolecular hydrogen bond is missing.

The effects of substitution and intramolecular charge transfer on linear and nonlinear optical absorptions (especially two photon absorption) of these \{BODIPY\} derivatives were investigated. Drastic spectral changes of aza-BODIPY compounds containing hydroxy group were observed in linear absorption spectra depending on basicity of solution. New bands in linear absorption spectra of phenolate form of these compounds appeared bellow 500 nm and above 700 nm in \{THF\} solution. These findings were caused by occurrence of the intramolecular charge transfer state in the phenolate form. Ultrafast pump probe spectroscopy experiments revealed that phenolic form shows only bleaching signal around 600 nm. On the other hand, the phenolate form showed fast growing nonlinear absorption signals bellow 500 nm and above 700 nm regions in addition to the bleaching signal around 600 nm. Intramolecular charge transfer state occurs above 700 nm and the lifetime of this state is found on the order of ultrafast time scales. Since the excitation of the fluorescence experiments is at 600 nm there is no fluorescence signal due to the relaxation of the energy through intramolecular charge transfer state. Aza-BODIPY compounds containing methoxy group did not show any two photon absorption properties due to weak electron-donating strength of methoxy group while aza-BODIPY compounds containing hydroxyl showed two photon absorption properties in wide spectral range (1200--1450 nm).

Their synthesis is partly based on classical methodologies such as Pechmann reaction or Knoevenagel condensation{,} but it also sparked the discovery of completely new pathways. In very recent years so-called vertically expanded coumarins were synthesized{,} effectively expanding the portfolio of existing architectures. A subtle relationship exists between the structure of fused coumarins and their optical properties. Although absorption of UV-radiation and light is a unifying theme among these [small pi]-expanded coumarins{,} the fluorescence properties strongly depend on the structure. The mode of fusion{,} the type of additional ring and the presence of electron-donating and electron-withdrawing substituents all influence the photophysical parameters. Recent advances made it possible to modulate their absorption from 300 nm to 550 nm{,} resulting in new coumarins emitting orange light. This review serves as a guide through both synthesis strategies and structure-property relationship nuances. Strong intramolecular charge-transfer character made it possible to reach suitable values of two-photon absorption cross-section.

In the cases of Acridine Orange a second chemometric approach has been used as a reference. It is based on a decomposition of the recorded spectra into a product of target and projection matrices using non iterative partial least squares (NIPALS). The matrices are then rotated to give the correct concentrations, spectral profiles of the components and the equilibrium constant. The dimeric constants determined by the two methods were in excellent agreement, evidencing the accuracy of the analysis. From the calculated dimeric constant and monomer and dimer spectra, the structures of the dimeric forms of the studied dyes are estimated. }, author = {L. Antonov and G. Gergov and V. Petrov and M.

In this context, theoretical studies can be helpful, and as such, computational spectroscopy is rapidly evolving from a highly specialized research field toward a versatile and widespread tool. However, in the case of electronic spectra (e.g. UV/Vis, circular dichroism, photoelectron, and X-ray spectra), the most commonly used methods still rely on the computation of vertical excitation energies, which are further convoluted to simulate line shapes. Such treatment completely neglects the influence of nuclear motions, despite the well-recognized notion that a proper account of vibronic effects is often mandatory to correctly interpret experimental findings. Development and validation of improved models rooted into density functional theory (DFT) and its time-dependent extension (TD-DFT) is of course instrumental for the optimal balance between reliability and favorable scaling with the number of electrons. However, the implementation of easy-to-use and effective procedures to simulate vibrationally resolved electronic spectra, and their availability to a wide community of users, is at least equally important for reliable simulations of spectral line shapes for compounds of biological and technological interest. Here, such an approach has been applied to the study of the UV/Vis spectra of chlorophyll a. The results show that properly tailored approaches are feasible for state-of-the-art computational spectroscopy studies, and allow, with affordable computational resources, vibrational and environmental effects on the spectral line shapes to be taken into account for large systems.}, author = {Barone, Vincenzo and Biczysko, Malgorzata and Borkowska-Panek, Monika and Bloino, Julien}, date-added = {2015-08-19 09:06:58 +0000}, date-modified = {2015-08-19 09:07:01 +0000}, doi = {10.1002/cphc.201402300}, issn = {1439-7641}, journal = {ChemPhysChem}, keywords = {chlorophyll, environmental effects, line shapes, UV/Vis spectra, vibronic effects}, number = {15}, pages = {3355--3364}, publisher = {WILEY-VCH Verlag}, title = {A Multifrequency Virtual Spectrometer for Complex Bio-Organic Systems: Vibronic and Environmental Effects on the UV/Vis Spectrum of Chlorophyll a}, url = {http://dx.doi.org/10.1002/cphc.201402300}, volume = {15}, year = {2014}, bdsk-url-1 = {http://dx.doi.org/10.1002/cphc.201402300}} @article{Bai13, author = {Baiardi, Alberto and Bloino, Julien and Barone, Vincenzo}, date-added = {2015-08-19 08:51:20 +0000}, date-modified = {2015-08-19 08:51:31 +0000}, doi = {10.1021/ct400450k}, eprint = {http://dx.doi.org/10.1021/ct400450k}, journal = {J.

The results show that the algebraic diagrammatic construction method to second order (ADC(2)) provides excellent possibilities for reliable calculations of CT states. Significant improvements in the accuracy of the computed transition energies are obtained by using the scaled opposite-spin (SOS) variant of ADC(2). Solvent effects were examined on the basis of the conductor-like screening model (COSMO) which has been implemented recently in the ADC(2) method. The dielectric constant and the refractive index of dichloromethane have been chosen in the COSMO calculations to compare with experimental solvatochromic effects. The computation of optimized ground state geometries and enthalpies of formation has been performed at the second-order Moller-Plesset perturbation theory (MP2) level. By comparison with experimental data and with high-level coupled-cluster methods including explicitly correlated (F12) wave functions{,} the importance of the SOS approach is demonstrated for the ground state as well. In the benzene-TCNE complex{,} the two lowest electronic excitations are of CT character whereas in the naphthalene and anthracene TCNE complexes three low-lying CT states are observed. As expected{,} they are strongly stabilized by the solvent. Geometry optimization in the lowest excited state allowed the calculation of fluorescence transitions. Solvent effects lead to a zero gap between S1 and S0 for the anthracene-TCNE complex. Therefore{,} in the series of benzene-TCNE to anthracene a change from a radiative to a nonradiative decay mechanism to the ground state is to be expected.}, author = {Aquino, Adelia A.

In this work, we address the question why doubly excited states play a role in the low-energy region of the optical spectrum of molecular systems at all, since from a naive point of view one would expect their excitation energy approximately twice as large as the one of the corresponding single excitation. Furthermore, we show that extended-ADC(2) is well suited for the balanced calculation of the low-lying excited 2 1 A g - , 1 1 B u - and 1 1 B u + states of long all-trans polyenes, which are known to possess substantial double excitation character. A careful re-investigation of the performance of \{TDDFT\} calculations for these states reveals that the previously reported good performance for the 2 1 A g - state relies heavily on fortuitous cancellation of errors. Finally, the title question is answered such that for short polyenes the lowest excited 2 1 A g - and 1 1 B u - states can clearly be classified as doubly excited, whereas the 1 1 A g - ground state is essentially represented by the (ground-state) \{HF\} determinant. For longer polyenes, in addition to increasing double excitation contributions in the 2 1 A g - and 1 1 B u - states, the ground state itself aquires substantial double excitation character (45% in C22H24), so that the transition from the ground state to these excited states should not be addressed as the excitation of two electrons relative to the 1 1 A g - ground state. }, author = {Jan Hendrik Starcke and Michael Wormit and Jochen Schirmer and Andreas Dreuw}, date-added = {2015-06-25 12:20:40 +0000}, date-modified = {2015-06-25 12:20:55 +0000}, doi = {http://dx.doi.org/10.1016/j.chemphys.2006.07.020}, issn = {0301-0104}, journal = {Chem.

The originality of the system stems from the tunability of the photoreaction quantum yields and conversion yields as a function of the electronic structure. The latter could be varied by modifying the electron-donating character of the DTE-end substituents La-da-d (o{,}o) (a{,} D = H; b{,} D = OMe; c{,} D = NMe2; d{,} D = NBu2) and/or the Lewis character of the metal ion center Laa--ddZnX2 (o{,}o) (La-ca-c{,} X = OAc; Lddd{,} X = Cl). The orbital description of the doubly-open form (o{,}o) and half-closed form (o{,}c) predicts that double closure to the form (c{,}c) would occur using UV irradiation. Photokinetic studies on the complete series demonstrate that photocyclization proceeds following a sequential ring closure mechanism. They clearly point out distinct quantum yields for the first and second ring closures{,} the latter being characterized by a significantly lower value. Dramatic decrease in both the quantum yields of the ring-closure and ring-opening processes is demonstrated for the complex LddZnCl22 exhibiting the strongest charge-transfer character in the series investigated. These studies show that this series of DTE derivatives provides an efficient strategy to tune the photochromic properties through the combination of the electron-donor and electron-acceptor (D-A) groups.}, author = {Ordronneau, Lucie and Aubert, Vincent and Metivier, Remi and Ishow, Elena and Boixel, Julien and Nakatani, Keitaro and Ibersiene, Fatima and Hammoutene, Dalila and Boucekkine, Abdou and Le Bozec, Hubert and Guerchais, Veronique}, date-added = {2015-05-19 12:04:29 +0000}, date-modified = {2015-05-19 12:04:32 +0000}, doi = {10.1039/C2CP23333A}, issue = {8}, journal = {Phys.

We have employed CASSCF{,} MS-CASPT2{,} RI-ADC(2){,} OM2/MRCI{,} DFT{,} and TDDFT methods to study the mechanistic photochemistry of 2-phenylphenol{,} for which such an ESIPT has been observed experimentally. According to static electronic structure calculations{,} irradiation of 2-phenylphenol populates the bright S1 state{,} which has a rather flat potential in the Franck-Condon region (with a shallow enol minimum at the CASSCF level) and may undergo an essentially barrierless ESIPT to the more stable S1 keto species. There are two S1/S0 conical intersections that mediate relaxation to the ground state{,} one in the enol region and one in the keto region{,} with the latter one substantially lower in energy. After S1 [rightward arrow] S0 internal conversion{,} the transient keto species can return back to the S0 enol structure via reverse ground-state hydrogen transfer in a facile tautomerization. This mechanistic scenario is verified by OM2/MRCI-based fewest-switches surface-hopping simulations that provide detailed dynamic information. In these trajectories{,} ESIPT is complete within 118 fs; the corresponding S1 excited-state lifetime is computed to be 373 fs in vacuum. Most of the trajectories decay to the ground state via the S1/S0 conical intersection in the keto region (67%){,} and the remaining ones via the enol region (33%). The combination of static electronic structure computations and nonadiabatic dynamics simulations is expected to be generally useful for understanding the mechanistic photophysics and photochemistry of molecules with intramolecular hydrogen bonds.}, author = {Xia, Shu-Hua and Xie, Bin-Bin and Fang, Qiu and Cui, Ganglong and Thiel, Walter}, date-added = {2015-04-20 14:12:36 +0000}, date-modified = {2015-04-20 14:12:41 +0000}, doi = {10.1039/C5CP00101C}, issue = {15}, journal = {Phys.

These compounds exhibit fluorosolvatochromism, namely the emission band is red shifted with increasing solvent polarity. Moreover, the absorption and emission properties of the styryl derivatives change drastically upon acidification, as the protonation of the nitrogen atoms of the imidazo[1,2-a]pyridine ring increases the donor-acceptor interplay of the π system. }, author = {Zeynel Sefero{\u g}lu and Heiko Ihmels and Ertan {\c S}ahin}, date-added = {2015-03-19 08:03:13 +0000}, date-modified = {2015-06-23 11:20:54 +0000}, doi = {http://dx.doi.org/10.1016/j.dyepig.2014.09.016}, issn = {0143-7208}, journal = {Dyes Pigm.}, keywords = {Fluorosolvatochromic dyes}, pages = {465--473}, title = {Synthesis and photophysical properties of fluorescent arylstyrylimidazo[1,2-a]pyridine-based donor-acceptor chromophores}, url = {http://www.sciencedirect.com/science/article/pii/S0143720814003751}, volume = {113}, year = {2015}, bdsk-url-1 = {http://www.sciencedirect.com/science/article/pii/S0143720814003751}, bdsk-url-2 = {http://dx.doi.org/10.1016/j.dyepig.2014.09.016}} @inbook{Reb13, author = {Rebolini, E. and Toulouse, J. and Savin, A.}, date-added = {2015-03-18 15:33:28 +0000}, date-modified = {2015-03-18 15:36:06 +0000}, editor = {Swapan Kumar Ghosh and Pratim Kumar Chattaraj}, pages = {367--390}, publisher = {CRC Press}, title = {Concepts and Methods in Modern Theoretical Chemistry: Electronic Structure and Reactivity}, year = {2013}} @article{Von96, author = {von Barth, Ulf and Holm, Bengt}, date-added = {2015-03-16 19:30:49 +0000}, date-modified = {2015-03-16 19:31:02 +0000}, doi = {10.1103/PhysRevB.54.8411}, issue = {12}, journal = {Phys.

Herein we demonstrate that replacing thiophene with furan in a phthalimide based molecular semiconductor results in a complete loss of electron mobility when evaluated using organic thin film transistors (OTFTs). Although optical, electronic, thermal, and structural characterization show subtle effects substituting furan for thiophene, theoretical dimer modeling employing the respective single crystal structures of the two molecules reveals a loss of degeneracy between the lowest unoccupied molecular orbital (LUMO) and LUMO+1 molecular orbitals in the bifuran-containing molecule. These results demonstrate that minor changes to molecular structure can result in large differences in device performance. }, author = {Arthur D. Hendsbee and Jon-Paul Sun and Theresa M.

Excitation energies to the S(1) (ππ*) and S(2) (πσ*) states are obtained by quantum chemical calculations at the MP2 and CC2 level using the aug-cc-pVDZ basis set for the ground-state and the S(1) optimized geometries. The observed lifetimes and the energy gaps between the ππ* and πσ* states show a good correlation, the lifetime being shorter for a smaller energy gap.

After testing several active spaces and basis sets, a CAS (14,12) active space together with an ANO-S basis set was found an appropriate choice to describe the vertical singlet and triplet electronic states of APO. Unfortunately, TD-DFT and CC2 methods cannot reproduce the MS-CASPT2 and experimental spectrum. Our MS-CASPT2//CASSCF(14,12)/ANO-S calculations predict a predominant pi*(OO)sigma*(OO) character for the lowest singlet excited state S(1) at 3.85 eV. Accordingly, the lowest singlet state of APO should be responsible for homolysis of the endoperoxide group. The next two absorbing excited states, experimentally proposed to be responsible for singlet oxygen production and therefore connected to the biological interest of APO, have been computed vertically at 4.34 and 4.59 eV and assigned to pi(CC)pi*(CC) and pi*(OO)pi*(CC) transitions, respectively. The vertical triplet electronic spectrum follows the singlet vertical spectrum ordering. The high density of triplet and singlet excited states of different nature within few eV points to the possibility of intersystem crossings between potential energy surfaces of different multiplicity.}, author = {Corral, In{\'e}s and Gonz{\'a}lez, Leticia}, date-added = {2015-02-08 17:56:59 +0000}, date-modified = {2015-02-08 17:57:09 +0000}, doi = {10.1002/jcc.20949}, institution = {Institut f{\"u}r Physikalische Chemie, Friedrich-Schiller-Universit{\"a}t Jena, Helmholtzweg 4, 07743 Jena, Germany.}, journal = {J.

Using the recently developed unrestricted algebraic-diagrammatic construction scheme of second order perturbation theory and the equation-of-motion coupled-cluster method, the vertical excitation energies, their corresponding oscillator strengths, and the nature of the wave functions of the lowest excited electronic states of the radicals are calculated and analyzed in detail. For the polyenyl radicals two one-photon allowed states are found as D(1) and D(4) states, with two symmetry-forbidden D(2) and D(3) states in between, while in the polyene radical cations D(1) and D(2) are allowed and D(3) is forbidden. The order of the states is conserved with increasing chain length. It is found that all low-lying excited states exhibit a significant but similar amount of doubly excited configuration in their wave functions of 15\%-20\%.

Both molecules exhibit the same 'fluorescent backbone', but due to the additional phenyl groups, the backbone of Rub is twisted, whereas it is planar for Tc. In agreement with earlier investigations, optical spectroscopy of the respective solutions reveals that the S 0 →S 1 transition in Rub is red-shifted with respect to Tc by ~2000 cm --1 and that Rub exhibits a considerably larger Stokes shift. In order to unravel the physical origin of these differences, we have performed a detailed normal coordinate analysis and frequency calculations using density functional theory (DFT) in conjunction with linear response time-dependent DFT (TD-DFT) energy scan calculations. The calculations yield dimensionless normal coordinate displacements of the excited-state origin that were employed for the calculation of the vibrational finestructure of the absorption and fluorescence spectra of Tc and Rub. The purely theoretical displacements were subsequently refined through fitting to the experimental spectra using the time-dependent theory of electronic spectroscopy. The analysis reveals that the ~2000 cm --1 red shift of the 0--0 vibronic band of Rub relative to Tc is mainly caused by the inductive effect of the phenyl substituents that leads to destabilization of the donor molecular orbital (MO) (the highest occupied molecular orbital (HOMO)). The large Stokes shift of 820 cm --1 observed for Rub is found to originate mainly from unresolved vibrational progressions involving low-frequency modes that are characterized by appreciable displacements in the excited state. The analysis shows that the spectra of Rub are strongly subject to temperature induced broadening, whereas for Tc this is much less significant.}, author = {T Petrenko and O Krylova and F Neese and M Sokolowski}, date-added = {2015-02-05 09:57:03 +0000}, date-modified = {2015-02-05 09:57:12 +0000}, journal = {New.

Two formalisms exist to compute excited state energies with polarizable solvation models: state-specific (SS) and linear-response (LR). The former more accurately describes the solute--solvent polarization in the excited state, but is computationally intensive. The \{LR\} formalism is efficient, but lacks proper relaxation effects. An approximate method, called corrected-LR (cLR), was originally formulated in the context of time-dependent density functional theory and the polarizable continuum model of solvation (PCM), and was shown to be able to recover most of the relaxation contributions of the \{SS\} formalism at a cost similar to LR. We have expanded the cLR idea to \{CC\} theory, and introduced an extra approximation that further reduces the computational effort with negligible loss of accuracy. The test cases reported in this contribution clearly show that the cLR-CC-PCM method is able to estimate transition energies in very close agreement with the \{SS\} formalism at a cost that is similar (in fact, slightly smaller) than the \{LR\} formalism. The average SS--LR difference is of the order of 0.10--0.20 eV for nonequilibrium calculations, and 0.30--0.55 eV for equilibrium calculations. The SS--cLR average difference is, on the other hand, 0.01--0.02 eV for nonequilibrium calculations, and 0.05--0.15 eV for equilibrium calculations. Therefore, the cLR approach is a promising alternative for computing excited state energies in solution with computationally intensive \{CC\} methods. }, author = {Marco Caricato}, date-added = {2015-01-23 13:08:06 +0000}, date-modified = {2021-04-14 16:06:29 +0200}, doi = {http://dx.doi.org/10.1016/j.comptc.2014.02.001}, issn = {2210-271X}, journal = {Comput.

The first approach employs two parameters to scale the two spin components of the direct term of CIS(D), starting from the two-parameter spin-component scaled (SCS) MP2 ground state, and is termed SCS--CIS(D). An efficient resolution-of-the-identity (RI) implementation of this approach is described. The second approach employs a single parameter to scale only the opposite-spin direct term of CIS(D), starting from the one-parameter scaled opposite-spin (SOS) MP2 ground state, and is called SOS--CIS(D). By utilizing auxiliary basis expansions and a Laplace transform, a fourth-order algorithm for SOS--CIS(D) is described and implemented. The parameters that describe SCS--CIS(D) and SOS--CIS(D) are optimized based on a training set that includes valence excitations of various organic molecules and Rydberg transitions of water and ammonia, and they significantly improve upon CIS(D) itself. The accuracy of the two methods is found to be comparable. This arises from a strong correlation between the same-spin and the opposite-spin portions of the excitation energy terms. The methods are successfully applied to the zincbacteriochlorin--bacteriochlorin charge-transfer transition, for which time-dependent density functional theory, with presently available exchange-correlation functionals, is known to fail. The methods are also successfully applied to describe various electronic transitions outside of the training set. The efficiency of the SOS--CIS(D) and the auxiliary basis implementation of CIS(D) and SCS--CIS(D) are confirmed with a series of timing tests. }, author = {Rhee, Young Min and Head-Gordon, Martin}, date-added = {2014-11-24 15:19:48 +0000}, date-modified = {2021-01-28 14:54:55 +0100}, doi = {10.1021/jp068409j}, eprint = {http://dx.doi.org/10.1021/jp068409j}, journal = {J.

The excitation energies calculated by \{CC2\} are significantly overestimated by 0.42--0.59 eV because of the substantial contributions of double excitation levels to excited states (>10%). However, the calculated \{XMCQDPT2\} excitation energies agree well with experimental ones within the accuracy 0.11--0.20 eV. The very low lasing efficiency (7.8--8.4%) of 4PhDPM compound was explained by the T1 → T4 and T1 → T5 reabsorptions at \{XMCQDPT2\} level of theory. The molecular photonics of pyrromethenes are studied using a combination of the first-principle and semi-empirical calculations. The main mechanism for the deactivation of the energy of the first singlet excited electronic state is the radiative electronic transition for DPMI, DPMII, \{PM567\} and 4PhDPM compounds. Also, the main mechanism for the quenching of fluorescence in considered complexes (except \{DPMII\} compound) is the internal conversion. The processes of the internal conversion and intersystem crossing compete with each other in \{DPMII\} compound. The measured and calculated fluorescence quantum yields agree well for all considered molecules. }, author = {R.R. Valiev and A.N. Sinelnikov and Y.V. Aksenova and R.T. Kuznetsova and M.B.

Four of these materials{,} viz. [small alpha]-[(4{,}5-dihydro-4{,}4-dimethyl-2-oxazolyl)methylene]benzenemethanol (3a){,} [small alpha]-[(4{,}5-dihydro-4{,}4-dimethyl-2-oxazolyl)methylene]-(4-nitrobenzene)methanol (3b){,} 1-(4{,}5-dihydro-4{,}4-dimethyl-2-oxazolyl)-3{,}3-dimethyl-1-buten-2-ol (3d) and (E)-1-phenyl-2-((3aR)-3{,}3a{,}8{,}8a-tetrahydro-2H-indeno[1{,}2-d]oxazol-2-ylidene)ethanone (3f) have been characterised in the solid-state by single crystal X-ray diffraction studies. These data represent the first solid-state structural studies of this class of compounds and details the first synthesis and full characterisation of chiral derivative 3f. All four of these materials are shown to exist in the solid phase in the enamine tautomeric form (e.g.{,} 3a is best described as 2-[4{,}4-dimethyl-2-oxazolidinylidene]-1-phenylethanone) and it is suggested (NMR{,} IR) that this isomeric form is likely also retained in solution (e.g.{,} CDCl3) as the more stable isomer. An investigation of the relative gas phase stabilities of the three possible (i.e.{,} the (Z)-enol{,} keto and enamine) isomers of all five compounds by DFT at the B3LYP/6-311G(d) level of theory confirms the latter as the most stable form. The energy differences between the enamine and keto tautomers have been calculated to be the lowest for derivative 3d. These results are compared and contrasted with the previously reported NMR studies of such compounds which have identified the keto form as being a minor (albeit solution) tautomer. Equilibrium solution tautomer distributions for 3d are found to be solvent dependent. The protonated form of 3a{,} isolated as the HSO4- salt (i.e.4a){,} has been further characterised in the solid state by single crystal X-ray diffraction. These data represent the first example of a protonated oxazoline to be structurally elucidated and confirms that upon protonation{,} the keto (oxazoline) tautomer is the energetically favoured form in the solid-state. This observation is further supported by DFT studies for the gas phase protonated forms of such materials. Further DFT (B3LYP/6-311G(d)) calculations employing the SM8 or SMD solvation models were then applied to address the observed solution isomeric distribution for 3d; these results corroborate the gas phase theoretical treatment and also yield values that predict the higher solution stability of the enamine form as observed{,} although they fail to account for the existence of the keto form as a minor solution state tautomer. To access the availability of an enol-form{,} via hypothetical de-protonation to the enolate{,} compound 3a was treated with hydrated Cu(NO3)2 in EtOH solution. The resulting isolated green-coloured product (5){,} the first metal derivative of this entire class of ligands{,} is best described (IR{,} X-ray diffraction) as a coordinated enolate complex{,} i.e.{,} Cu(3a-H)2. Complex 5 crystallizes in the P21/c space group with four molecules in the unit cell. The coordination geometry around the formal Cu2+ metal centre is determined to be highly distorted square planar in nature ([small tau]4 = 0.442). TD-DFT is used to give a reasonable explanation for the intensity of the absorbance band observed in the visible region for solutions of 5.

The selected protocol accounts for the impact of solvation using a corrected linear-response continuum approach and vibrational corrections through calculations of the zero-point energies of both ground and excited-states and provides basis set converged data thanks to the systematic use of diffuse-containing atomic basis sets at all computational steps. It turns out that an optimally tuned long-range corrected hybrid form of the Perdew--Burke--Ernzerhof functional, LC-PBE*, delivers both the smallest mean absolute error (0.20 eV) and standard deviation (0.15 eV) of all tested approaches, while the obtained correlation (0.93) is large but remains slightly smaller than its M06-2X counterpart (0.95). In addition, the efficiency of two other recently developed exchange-correlation functionals, namely SOGGA11-X and ωB97X-D, has been determined in order to allow more complete comparisons with previously published data. }, author = {Jacquemin, Denis and Moore, Barry and Planchat, Aur{\'e}lien and Adamo, Carlo and Autschbach, Jochen}, date-added = {2014-07-15 07:44:41 +0000}, date-modified = {2014-07-15 08:10:33 +0000}, doi = {10.1021/ct5000617}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct5000617}, journal = {J.

Solvent effects are further analyzed by means of a polarizable continuum model. A total of 15 organic chromophores (including both small molecules and larger push--pull systems) are considered as prototypes of n → π* and π → π* singlet excitations. Our analysis allows to point out specific correlations between the accuracy of the various functionals and the type of excitation and/or the type of chemical bonds involved. We find that while the best ground-state geometries are obtained with PBE0 and B3LYP, CAM-B3LYP yields the most accurate description of electronic and geometrical characteristics of excited states, both in gas-phase and in solution. }, author = {Guido, Ciro A. and Knecht, Stefan and Kongsted, Jacob and Mennucci, Benedetta}, date-added = {2014-06-19 07:38:28 +0000}, date-modified = {2014-06-19 07:38:37 +0000}, doi = {10.1021/ct400021c}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct400021c}, journal = {J.

In contrast to the CASSCF photoisomerization mechanism of bond inversion followed by torsion around formal double bonds, we find that the other approaches predict an initial skeletal relaxation which does not lead to bond inversion but to a rather flexible retinal chromophore with longer bonds and with the bond-length pattern of the ground state being partly preserved. The relaxation proceeds then preferentially via partial torsion around formal single bonds and does not reach a conical intersection region. Our findings are compatible with solution experiments which point to the existence of multiple minima and relaxation pathways, some of which are nonreactive, do not lead to photoproducts via conical intersection, and are dominant in solution. Our results also demonstrate the importance of a balanced description of dynamical and static correlation in the excited-state gradients and raise serious concerns on the common use of the CASSCF method to investigate structural properties of photoexcited retinal systems. }, author = {Valsson, Omar and Filippi, Claudia}, date-added = {2014-06-19 06:52:39 +0000}, date-modified = {2014-06-19 06:52:46 +0000}, doi = {10.1021/ct900692y}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct900692y}, journal = {J.

It is based on the evolution of the emission spectrum observed by UV--vis pump--probe absorption measurements with a cross correlation of 35 fs. The rise of the emission is delayed by 33 fs and reveals the time the wave packet needs to evolve along the reaction coordinate. Four decisive molecular motions and their role during the process are identified by the frequencies and phases extracted from the oscillatory signal contributions. A novel model is developed that describes the ESIPT as a ballistic wave packet motion consisting of three major components:  First, the H-chelate ring contracts by in-plane bending of the whole molecule, resulting in an acceleration along the corresponding normal mode. The time scale of the motion is given by the inertia of the participating atoms. When the ON distance is sufficiently shortened, the electronic configuration changes, new bonds are formed, and a new equilibrium geometry results. The molecule is now displaced with respect to this geometry and begins to oscillate in those modes that have large projections on the displacement. The proton is shifted passively toward the nitrogen by the initial contraction of the ring and stays there because of the electronic configuration change. }, author = {Lochbrunner, Stefan and Wurzer, Alexander J. and Riedle, Eberhard}, date-added = {2014-05-20 09:11:40 +0000}, date-modified = {2014-05-20 09:11:46 +0000}, doi = {10.1021/jp035203z}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp035203z}, journal = {J.

In all the studied cases, the fluorescence decay kinetics of both short-wavelength normal (N*) and long-wavelength tautomer (T*) bands can be characterized by the same two lifetime components, which are constant over the all wavelength range of the emission. In the meantime, the preexponential factor of the short-lifetime component changes its sign, being positive for the N* and negative for the T* emission band. Moreover, the two preexponential factors of the T* emission decay are the same in magnitude but opposite in sign. These features are characteristic of a fast reversible two-state ESIPT reaction. Reconstruction of time-resolved spectra allows observing the evolution of these spectra with the appearance, rapid growth, and stabilization (in less than 200 ps) of the relative intensities of the two emission bands. A detailed kinetic model was applied for the analysis of these data, which involved the determination of radiative and nonradiative decay rate constants of both N* and T* forms and of forward and reverse rate constants for transitions between them. We show that ESIPT reaction in the studied conditions occurs on the scale of tens of picoseconds and thus is uncoupled with dielectric relaxations in the solvent occurring at subpicosecond times. Moreover, the radiative and nonradiative deactivation processes were found to be much slower than the ESIPT reaction, suggesting that the relative intensities of the two emission bands are mainly governed by the ESIPT equilibrium. Therefore, both electrochromic and solvatochromic effects on the relative intensities of the two emission bands in 4`-(dialkylamino)-3-hydroxyflavones result from the shifts in the ESIPT equilibrium.}, author = {Shynkar, Vasyl V. and Mely, Yves and Duportail, Guy and Piemont, Etienne and Klymchenko, Andrey S. and Demchenko, Alexander P.}, date-added = {2014-05-20 06:43:27 +0000}, date-modified = {2014-05-20 06:43:31 +0000}, doi = {10.1021/jp035855n}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp035855n}, journal = {J.

The focus was on substituents that change the distribution of electronic density on the chromophore and their influence on these reaction rates. Shpol'skii spectroscopy was applied for comparative studies of three compounds:  3HF, 3-hydroxy-4`-methoxyflavone (3HF-4`OMe), and 2-furyl-3-hydroxychromone (3HC--F). By comparing the spectral bandwidths with those of deuterated analogues, we could distinguish the lifetime broadening components in the high-resolution excitation and emission spectra, from which the time constants of the ESIPT and BPT reactions were calculated. The time constants for the ESIPT reaction were 0.093 ps for 3HF, 0.21 ps for 3HF-4`OMe, and slower than 0.6 ps for 3HC--F. For the same compounds, the BPT rates were 0.21, 0.47, and >2 ps, respectively. No change in bandwidth was observed over the temperature range 4--20 K, in agreement with a tunneling mechanism. Estimates for the barrier heights and proton-transfer distances are given. In addition, a systematic change in O--H bond strengths between ground and excited states was calculated from the isotope effect, observed as the shifts of the 0--0 bands in the excitation and emission spectra upon deuteration. The substantial effect of electron donating substituents on the rates of ESIPT and BPT reactions is in agreement with these changes.}, author = {Bader, Arjen N. and Pivovarenko, Vasyl G. and Demchenko, Alexander P. and Ariese, Freek and Gooijer, Cees}, date-added = {2014-05-20 06:43:00 +0000}, date-modified = {2014-05-20 06:43:09 +0000}, doi = {10.1021/jp048925e}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp048925e}, journal = {J.

The dual fluorescence observed for 5-methylsalicylic acid (5-MeSA) in alkane solutions has been attributed for its blue part to the excited tautomer resulting from the intramolecular proton-transfer process and for its UV component to the dimer. A single fluorescence emission peaking at 400 nm is observed in alkane solutions of 5-methoxysalicylic acid (5-MeOSA). In the presence of proton acceptors such as diethyl ether, the 5-MeSA solution emits only in the blue region while 5-MeOSA exhibits two fluorescence bands at 400 and 475 nm. This behavior shows that the ESIPT process is promoted by complexation with proton-accepting molecules. In the supersonic expansion, the excitation and dispersed emission spectra of 5-MeSA are very similar to those previously observed for unsubstituted salicylic acid and show that the ESIPT mechanism takes place without barrier, in agreement with the model of a distorted potential surface in the excited state. In contrast, the 5-MeOSA excitation and dispersed fluorescence spectra present a mirror-image relationship that indicates that the molecule keeps a similar geometry in the ground and excited state. In this case the ESIPT reaction is prevented. Complexation with diethyl ether and acetone does not give rise to a dual fluorescence as in solutions but results in a broad emission extending toward the visible. This result may be explained by a modification of the excited potential energy surface along the tautomerization coordinate without introducing an energy barrier in the proton-transfer reaction. }, author = {Lahmani, F. and Zehnacker-Rentien, A.}, date-added = {2014-05-20 06:37:22 +0000}, date-modified = {2014-05-20 06:37:27 +0000}, doi = {10.1021/jp9712516}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp9712516}, journal = {J.

The role of proton in the course of proton transfer, whether it is active or passive, has been the subject of intense investigations. Here we demonstrate the active role of proton in the excited state intramolecular proton transfer (ESIPT) of 10-hydroxybenzo[h]quinoline (HBQ). The ESIPT of HBQ proceeds in 12 $\pm$ 6 fs, and the rate is slowed down to 25 $\pm$ 5 fs for DBQ where the reactive hydrogen is replaced by deuterium. The results are consistent with the ballistic proton wave packet transfer within the experimental uncertainty. This ultrafast proton transfer leads to the coherent excitation of the vibrational modes of the product state. In contrast, ESIPT of 2-(2′-hydroxyphenyl)benzothiazole (HBT) is much slower at 62 fs and shows no isotope dependence implying complete passive role of the proton. }, author = {Lee, Junghwa and Kim, Chul Hoon and Joo, Taiha}, date-added = {2014-02-04 17:06:08 +0000}, date-modified = {2014-02-04 17:06:11 +0000}, doi = {10.1021/jp311884b}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp311884b}, journal = {J.

In contrast to the native GFP core, 4-(4-hydroxybenzylidene)-1,2-dimethyl-1H-imidazol-5(4H)-one (p-HBDI), which requires hydrogen-bonding relay to accomplish proton transfer in vivo, o-HBDI possesses a seven-membered-ring intramolecular hydrogen bond and thus provides an ideal system for mimicking an intrinsic proton-transfer reaction. Upon excitation, ESIPT takes place in o-HBDI, resulting in a ∼600 nm proton-transfer tautomer emission. The o-HBDI tautomer emission, resolved by fluorescence upconversion, is comprised of an instantaneous rise to a few hundred femtosecond oscillation in the early relaxation stage. Frequency analysis derived from ultrashort pulse gives two low-frequency vibrations at 115 and 236 cm--1, corresponding to skeletal deformation motions associated with the hydrogen bond. The results further conclude that ESIPT in o-HBDI is essentially triggered by low-frequency motions and may be barrierless along the reaction coordinate. Femtosecond UV/vis transient absorption spectra also provide supplementary evidence for the structural evolution during the reaction. In CH3CN, an instant rise of a 530 nm transient is resolved, which then undergoes 7.8 ps decay, accompanied by the growth of a rather long-lived 580 nm transient species. It is thus concluded that following ESIPT the cis-proton transfer isomer undergoes cis--trans-isomerization. The results of viscosity-dependent dynamics are in favor of the one-bond-flip mechanism, which is in contrast to the volume-conserving isomerization behavior for cis-stilbene and p-HBDI. Further confirmation is given by the picosecond--femtosecond transient IR absorption spectra, where several new and long-lived IR bands in the range of 1400--1500 cm--1 are assigned to the phenyl in-plane breathing motions of the trans-proton transfer tautomer. Monitored by the nanosecond transient absorption, the 580 nm transient undergoes a ∼7.7 μs decay constant, accompanied by the growth of a new ∼500 nm band. The latter is assigned to a deprotonated tautomer species, which then undergoes the ground-state reverse proton recombination to the original o-HBDI in ∼50 μs, achieving an overall, reversible proton transfer cycle. This assignment is unambiguously supported by pump--probe laser induced fluorescence studies. On these standpoints, a comparison of photophysical properties among o-HBDI, p-HBDI, and wild-type GFP is discussed in detail. }, author = {Hsieh, Cheng-Chih and Chou, Pi-Tai and Shih, Chun-Wei and Chuang, Wei-Ti and Chung, Min-Wen and Lee, Junghwa and Joo, Taiha}, date-added = {2014-02-04 17:04:58 +0000}, date-modified = {2014-02-04 17:05:03 +0000}, doi = {10.1021/ja107945m}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ja107945m}, journal = {J.

Tinuvin P (TIN P, 11a) and six other HBzTs, with no substituent in the 3`-position ortho to the hydroxy function, show pronounced phosphorescence already in the dark (at 77 K in a polar glass). Upon irradiation, the phosphorescence intensity rises further until an equilibrium value is attained (up to 1.5 fold the dark value). A kinetic model is given which excellently reproduces this phosphorescence evolution:  it demonstrates phosphorescence to arise from open conformers where the IMHB has been broken. Phosphorescence excitation spectra match the absorption spectra of the open conformer and also that of the O-methyl homologue 11A which cannot form an IMHB. Fluorescence spectra likewise prove the equilibrium between the closed and open conformer for these HBzTs. In unpolar glasses as well as in the crystalline state, TIN P displays a long-wavelength (red) fluorescence (with an enormous Stokes shift of ∼10.000 cm-1) which is associated with the excited singlet state of the closed form after proton transfer within the IMHB, S1`(C). In polar matrixes, on the other hand, a blue fluorescence is observed (with a regular Stokes shift) for all those HBzTs which have no 3`-substituent shielding the IMHB against being opened by the polar solvent. This blue fluorescence, just as the characteristic phosphorescence evolution for these compounds, is associated with the open conformer. For HBzTs with an (alkyl) group ortho to the bridging OH group, however, a long-wavelength (red) fluorescence is again observed. The shielding effect of the 3`-substituent shows a fine gradation, cumyl ≥ 1,1,3,3-tetramethylbutyl (isooctyl) > t-butyl ≥ methyl. }, author = {Fluegge, Anja P. and Waiblinger, Frank and Stein, Martin and Keck, Juergen and Kramer, Horst E.

DFT calculations indicate the different association abilities of the dyes and the enhancement of ICT upon addition of the metal cations. }, author = {Feng, Xin Jiang and Tian, Pin Zhan and Xu, Zheng and Chen, Shao Fu and Wong, Man Shing}, date-added = {2014-02-04 12:31:52 +0000}, date-modified = {2014-02-04 12:33:13 +0000}, doi = {10.1021/jo401808c}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jo401808c}, journal = {J.

Kohn--Sham density functional theory (DFT) is used to calculate both ground (So) and first excited (S1) states using the maximum overlap method to obtain the S1 state. This approach gives ground and excited state structures in good agreement with structures found using multiconfigurational perturbation theory (CASPT2). Application of a post-self-consistent field spin-purification relationship also yields transition energies in agreement with CASPT2 and available experimental data. Spectral bands were simulated using many structures taken from ab initio molecular dynamics simulations of the ground and first excited states. In these simulations, DFT is used for BODIPY, and in the condensed phase simulations the water molecules are treated classically. The resulting spectra show a blue shift of 0.3 eV in both absorption and emission bands in water compared to the gas phase. A Stokes shift of about 0.1 eV is predicted, and the width of the emission band in solution is significantly broader than the absorption band. These results are consistent with experimental data for BODIPY and closely related dyes, and demonstrate how both absorption and emission spectra in solution can be simulated using a quantum mechanical treatment of the electronic structure of the solute. }, author = {Briggs, Edward A. and Besley, Nicholas A. and Robinson, David}, date-added = {2013-12-31 12:22:48 +0000}, date-modified = {2013-12-31 12:23:38 +0000}, doi = {10.1021/jp312229b}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp312229b}, journal = {J.

Although these two heme dioxygenases were discovered more than 40 years ago, their reaction mechanisms were still poorly understood. Encouraged by recent X-ray crystal structures, new mechanistic pathways were proposed. We performed ONIOM(B3LYP:Amber) calculations with explicit consideration of the protein environment to study various possible reaction mechanisms for bacterial TDO. The ONIOM calculations do not support the proposed mechanisms (via either formation of the dioxetane intermediate or Criegee-type rearrangement); a mechanism that is exceptional in the hemes emerges. It starts with (1) direct radical addition of a ferric-superoxide intermediate with C2 of the indole of Trp, followed by (2) ring-closure via homolytic O-O cleavage to give epoxide and ferryl-oxo (Cpd II) intermediates, (3) acid-catalyzed regiospecific ring-opening of the epoxide, (4) oxo-attack, and (5) finally C-C bond cleavage concerted with back proton transfer. The involvement of dual oxidants, ferric-superoxide and ferryl-oxo (Cpd II) intermediates, is proposed to be responsible for the dioxygenase reactivity in bacterial TDO. In particular, the not-well-recognized ferric-superoxide porphyrin intermediate is found to be capable of reacting with pi-systems via direct radical addition, an uncommon dioxygen activation in the hemes.

We use a recently developed quantum-mechanics/molecular mechanics (QM/MM) method that allows us to account for pigment-protein interactions at atomic detail in site energies, transition dipole moments, and electronic couplings. In addition, conformational flexibility of the pigment-protein complex is accounted for through molecular dynamics (MD) simulations. We find that conformational disorder largely smoothes the large energetic differences predicted from the crystal structure between the pseudosymmetric pairs PEB50/61C-PEB50/61D and PEB82C-PEB82D. Moreover, we find that, in contrast to chlorophyll-based photosynthetic complexes, pigment composition and conformation play a major role in defining the energy ladder in the PE545 complex, rather than specific pigment-protein interactions. This is explained by the remarkable conformational flexibility of the eight bilin pigments in PE545, characterized by a quasi-linear arrangement of four pyrrole units. The MD-QM/MM site energies allow us to reproduce the main features of the spectra, and minor adjustments of the energies of the three red-most pigments DBV19A, DBV19B, and PEB82D allow us to model the spectra of PE545 with a similar quality compared to our original model (model E from Novoderezhkin et al. Biophys. J.2010, 99, 344), which was extracted from the spectral and kinetic fit. Moreover, the fit of the transient absorption kinetics is even better in the new structure-based model. The largest difference between our previous and present results is that the MD-QM/MM calculations predict a much smaller gap between the PEB50/61C and PEB50/61D sites, in better accord with chemical intuition. We conclude that the current adjusted MD-QM/MM energies are more reliable in order to explore the spectral properties and energy transfer dynamics in the PE545 complex.}, author = {Curutchet, Carles and Novoderezhkin, Vladimir I. and Kongsted, Jacob and Mu{\~n}oz-Losa, Aurora and {van Grondelle}, Rienk and Scholes, Gregory D. and Mennucci, Benedetta}, date-added = {2013-12-18 20:29:11 +0000}, date-modified = {2016-10-08 17:33:03 +0000}, doi = {10.1021/jp305033d}, institution = {Departament de Fisicoqu{\'\i}mica, Facultat de Farm{\`a}cia, Universitat de Barcelona, Av.

Here we present a novel multiscale QM/continuum approach which can both treat MNP-solvent-mediated EET and take into account the effects of the MNPs in all the photophysical processes into play (absorption and emission), including the competitive energy transfer from the molecular systems to the metal. By applying such a unified theoretical framework, we show that the excitonic interactions in stacked dimers are generally reduced by the presence of MNPs. In contrast, for setups in which the two transferring moieties are separated by the MNPs, the presence of the metal results in a direct enhancement of the coupling but, when the competing process of quenching by the MNP is also considered, the final effect is almost invariably a reduction of the efficiency of the EET process. Only for particular donor-MNP-acceptor setups, the model shows that waveguide-like behavior can be obtained, in these cases the excitation energy of the donor can be transferred to the acceptor over distances much longer than those allowed by the conventional F{\"o}rster mechanism.}, author = {Angioni, Ambra and Corni, Stefano and Mennucci, Benedetta}, date-added = {2013-12-18 20:29:01 +0000}, date-modified = {2013-12-18 20:29:01 +0000}, doi = {10.1039/c2cp44010e}, institution = {Dipartimento di Chimica e Chimica Industriale, University of Pisa, Via Risorgimento 35, 56126 Pisa, Italy.}, journal = {Phys Chem Chem Phys}, language = {eng}, medline-pst = {ppublish}, month = {Mar}, number = {9}, pages = {3294--3303}, pmid = {23361439}, title = {Can we control the electronic energy transfer in molecular dyads through metal nanoparticles?

In the first coupling method we perform a single quantum-mechanical (QM) calculation to characterize the excited state behavior, specifically the transition dipole moment, of the fluorescent probe, which is then mapped onto the configuration space sampled by MD. We then utilize these transition dipoles within the ideal dipole approximation (IDA) to determine the electronic coupling between the probes that mediates the transfer of energy. In the second method we perform a QM calculation on each snapshot and use the complete transition densities to calculate the electronic coupling without need for the IDA. The resulting coupling trajectories are then sampled using three methods ranging from an independent sampling of each trajectory point (the independent snapshot method) to a Markov chain treatment that accounts for the dynamics of the coupling in determining effective rates. The results show that the IDA significantly overestimates the energy transfer rate (by a factor of 2.6) during the portions of the trajectory in which the probes are close to each other. Comparison of the sampling methods shows that the Markov chain approach yields more realistic observables at both high and low FRET efficiencies. Differences between the three sampling methods are discussed in terms of the different mechanisms for averaging over structural dynamics in the system. Convergence of the Markov chain method is carefully examined. Together, the methods for estimating coupling and for sampling the coupling provide a mechanism for directly connecting the structural dynamics modeled by MD with fluorescence observables determined through FRET experiments.}, author = {Speelman, Amy L. and Mu{\~n}oz-Losa, Aurora and Hinkle, Katie L. and VanBeek, Darren B. and Mennucci, Benedetta and Krueger, Brent P.}, date-added = {2013-12-18 20:28:40 +0000}, date-modified = {2013-12-18 20:28:40 +0000}, doi = {10.1021/jp1095344}, institution = {Department of Chemistry, Hope College, Holland, Michigan 49423, United States.}, journal = JPCA, keywords = {Fluorescence; Fluorescent Dyes, chemistry; Models, Chemical; Models, Molecular; Molecular Dynamics Simulation; Muramidase, chemistry/metabolism; Quantum Theory}, language = {eng}, medline-pst = {ppublish}, month = {Apr}, number = {16}, pages = {3997--4008}, pmid = {21417498}, title = {Using molecular dynamics and quantum mechanics calculations to model fluorescence observables.}, url = {http://dx.doi.org/10.1021/jp1095344}, volume = {115}, year = {2011}, bdsk-url-1 = {http://dx.doi.org/10.1021/jp1095344}} @article{Hoe11, abstract = {F{\"o}rster Resonance Energy Transfer (FRET) experiments probe molecular distances via distance dependent energy transfer from an excited donor dye to an acceptor dye. Single molecule experiments not only probe average distances, but also distance distributions or even fluctuations, and thus provide a powerful tool to study biomolecular structure and dynamics. However, the measured energy transfer efficiency depends not only on the distance between the dyes, but also on their mutual orientation, which is typically inaccessible to experiments. Thus, assumptions on the orientation distributions and averages are usually made, limiting the accuracy of the distance distributions extracted from FRET experiments. Here, we demonstrate that by combining single molecule FRET experiments with the mutual dye orientation statistics obtained from Molecular Dynamics (MD) simulations, improved estimates of distances and distributions are obtained. From the simulated time-dependent mutual orientations, FRET efficiencies are calculated and the full statistics of individual photon absorption, energy transfer, and photon emission events is obtained from subsequent Monte Carlo (MC) simulations of the FRET kinetics. All recorded emission events are collected to bursts from which efficiency distributions are calculated in close resemblance to the actual FRET experiment, taking shot noise fully into account. Using polyproline chains with attached Alexa 488 and Alexa 594 dyes as a test system, we demonstrate the feasibility of this approach by direct comparison to experimental data. We identified cis-isomers and different static local environments as sources of the experimentally observed heterogeneity. Reconstructions of distance distributions from experimental data at different levels of theory demonstrate how the respective underlying assumptions and approximations affect the obtained accuracy.

Characterization of electron transfer (ET) and excitation energy transfer (EET) rates are essential for a full understanding of, for instance, biological systems (such as respiration and photosynthesis) and opto-electronic devices (which interconvert electric and light energy). In this Account, we examine one of the parameters, the electronic coupling factor, for which reliable values are critical in determining transfer rates. Although ET and EET are different processes, many strategies for calculating the couplings share common themes. We emphasize the similarities in basic assumptions between the computational methods for the ET and EET couplings, examine the differences, and summarize the properties, advantages, and limits of the different computational methods. The electronic coupling factor is an off-diagonal Hamiltonian matrix element between the initial and final diabatic states in the transport processes. ET coupling is essentially the interaction of the two molecular orbitals (MOs) where the electron occupancy is changed. Singlet excitation energy transfer (SEET), however, contains a Frster dipole-dipole coupling as its most important constituent. Triplet excitation energy transfer (TEET) involves an exchange of two electrons of different spin and energy; thus, it is like an overlap interaction of two pairs of MOs. Strategies for calculating ET and EET couplings can be classified as (1) energy-gap-based approaches, (2) direct calculation of the off-diagonal matrix elements, or (3) use of an additional operator to describe the extent of charge or excitation localization and to calculate the coupling value. Some of the difficulties in calculating the couplings were recently resolved. Methods were developed to remove the nondynamical correlation problem from the highly precise coupled cluster models for ET coupling. It is now possible to obtain reliable ET couplings from entry-level excited-state Hamiltonians. A scheme to calculate the EET coupling in a general class of systems, regardless of the contributing terms, was also developed. In the past, empirically derived parameters were heavily invoked in model description of charge and excitation energy drifts in a solid-state device. Recent advances, including the methods described in this Account, permit the first-principle quantum mechanical characterization of one class of the parameters in such descriptions, enhancing the predictive power and allowing a deeper understanding of the systems involved.}, author = {Hsu, Chao-Ping}, date-added = {2013-12-18 20:21:10 +0000}, date-modified = {2013-12-18 20:21:10 +0000}, doi = {10.1021/ar800153f}, institution = {Institute of Chemistry, Academia Sinica, 128 Section 2 Academia Road, Nankang, Taipei 115, Taiwan. cherri@sinica.edu.tw}, journal = {Acc Chem Res}, keywords = {Algorithms; Electron Transport; Electrons; Energy Transfer; Solvents, chemistry}, language = {eng}, medline-pst = {ppublish}, month = {Apr}, number = {4}, pages = {509--518}, pii = {10.1021/ar800153f}, pmid = {19215069}, title = {The electronic couplings in electron transfer and excitation energy transfer.}, url = {http://dx.doi.org/10.1021/ar800153f}, volume = {42}, year = {2009}, bdsk-url-1 = {http://dx.doi.org/10.1021/ar800153f}} @article{Sch05, author = {Schr{\"o}der, G.F. and Alexiev, U. and Grubm{\"u}ller, H.}, date-added = {2013-12-18 20:20:34 +0000}, date-modified = {2013-12-18 20:20:47 +0000}, journal = {Biophys.

The best results were obtained at the scalar relativistic ZORA level for the largest model in conjunction with explicit modeling of the protein environment through the QM/MM procedure, which is also considered to be the highest level of theory used in this work. The protein effects beyond the second coordination sphere were found to be quite substantial (up to 30% changes on some properties), and were found to require an explicit treatment of the protein beyond the second coordination sphere. In addition, the embedding water cage was found to have a nonnegligible influence on the calculated spectroscopic data, which is of the same order as the influence of the protein backbone charges. However, while qualitatively satisfactory, the errors in the calculated spectroscopic parameters are still substantial, and can all be traced back to the fact that the linear-response of the presently available functionals is ``too stiff'' with respect to the external perturbations at least for the model systems studied here. Ligand field-based approaches are used to correct for systematic errors in the DFT procedures. As a consequence, we propose a new breakdown of the copper hyperfine interaction into Fermi-contact, spin-dipolar and spin-orbit contributions.}, author = {Sinnecker, Sebastian and Neese, Frank}, date-added = {2013-12-18 13:01:54 +0000}, date-modified = {2013-12-18 13:01:54 +0000}, journal = JCC, number = {12}, pages = {1463--1475}, publisher = {Wiley Online Library}, title = {QM/MM calculations with DFT for taking into account protein effects on the EPR and optical spectra of metalloproteins.

Quantum mechanical methods can accurately simulate these processes, but they require considerably greater computational resources. Because electronic changes typically occur in a limited part of the system, such as the solute in a molecular solution or the substrate within the active site of enzymatic reactions, researchers can limit the quantum computation to this part of the system. Researchers take into account the influence of the surroundings by embedding this quantum computation into a calculation of the whole system described at the molecular mechanical level, a strategy known as the mixed quantum mechanics/molecular mechanics (QM/MM) approach. The accuracy of this embedding varies according to the types of interactions included, whether they are purely mechanical or classically electrostatic. This embedding can also introduce the induced polarization of the surroundings. The difficulty in QM/MM calculations comes from the splitting of the system into two parts, which requires severing the chemical bonds that link the quantum mechanical subsystem to the classical subsystem. Typically, researchers replace the quantoclassical atoms, those at the boundary between the subsystems, with a monovalent link atom. For example, researchers might add a hydrogen atom when a C-C bond is cut. This Account describes another approach, the Local Self Consistent Field (LSCF), which was developed in our laboratory. LSCF links the quantum mechanical portion of the molecule to the classical portion using a strictly localized bond orbital extracted from a small model molecule for each bond. In this scenario, the quantoclassical atom has an apparent nuclear charge of +1. To achieve correct bond lengths and force constants, we must take into account the inner shell of the atom: for an sp(3) carbon atom, we consider the two core 1s electrons and treat that carbon as an atom with three electrons. This results in an LSCF+3 model. Similarly, a nitrogen atom with a lone pair of electrons available for conjugation is treated as an atom with five electrons (LSCF+5). This approach is particularly well suited to splitting peptide bonds and other bonds that include carbon or nitrogen atoms. To embed the induced polarization within the calculation, researchers must use a polarizable force field. However, because the parameters of the usual force fields include an average of the induction effects, researchers typically can obtain satisfactory results without explicitly introducing the polarization. When considering electronic transitions, researchers must take into account the changes in the electronic polarization. One approach is to simulate the electronic cloud of the surroundings by a continuum whose dielectric constant is equal to the square of the refractive index. This Electronic Response of the Surroundings (ERS) methodology allows researchers to model the changes in induced polarization easily. We illustrate this approach by modeling the electronic absorption of tryptophan in human serum albumin (HSA).}, author = {Monari, Antonio and Rivail, Jean-Louis and Assfeld, Xavier}, date-added = {2013-12-18 12:30:15 +0000}, date-modified = {2017-08-22 16:31:46 +0000}, doi = {10.1021/ar300278j}, institution = {Th{\'e}orie Mod{\'e}lisation Simulation, Universit{\'e} de Lorraine, SRSMC UMR 7565, Vand{\oe}uvre-l{\`e}s-Nancy F-54506, France.}, journal = {Acc.

Generally these SLBOs are derived from localized bond orbitals (LBOs) that undergo tails deletion, resulting in a nonpredictable change of their properties. An alternative set of SLBOs is provided by the extremely localized molecular orbitals (ELMOs) approach, where the orbitals are rigorously localized on some prefixed atoms without tails on the other atoms of the molecule. A comparative study of SLBOs arising from various localization schemes and ELMOs is presented to test the reliability and the transferability of these functions within the Local Self-Consistent Field (LSCF) framework. Two types of chemical bonds were considered: C--C and C--O single bonds. The localized functions are obtained on the ethane and the methanol molecules, and are tested on beta-alanine and diethyl ether molecules. Moreover, the various protonation forms of beta-alanine have been investigated to illustrate how well the polarity variation of the chemical bond can be handled throughout a chemical process. At last, rotation energy profiles around C--C and C--O bonds are reproduced for butane and fluoromethanol. Energetic, geometric, as well as electronic factors all indicate that ELMO functions are much more transferable from one molecule to another, leading to results closer to the usual SCF reference than any other calculations involving any other localized orbitals.

Thus far, ruthenium(II) bipyridyl complexes have proven to be the most efficient TiO2 sensitizers in dye-sensitized solar cells. However, a gradual increment in the highest power conversion efficiency has been recognized in the past decade. More importantly, considering that ruthenium is a rare metal, novel dyes without metal or using inexpensive metal are desirable for highly efficient dye-sensitized solar cells. Large π-aromatic molecules, such as porphyrins, phthalocyanines, and perylenes, are important classes of potential sensitizers for highly efficient dye-sensitized solar cells, owing to their photostability and high light-harvesting capabilities that can allow applications in thinner, low-cost dye-sensitized solar cells. Porphyrins possess an intense Soret band at 400 nm and moderate Q bands at 600 nm. Nevertheless, the poor light-harvesting properties relative to the ruthenium complexes have limited the cell performance of porphyrin-sensitized TiO2 cells. Elongation of the π conjugation and loss of symmetry in porphyrins cause broadening and a red shift of the absorption bands together with an increasing intensity of the Q bands relative to that of the Soret band. On the basis of the strategy, the cell performance of porphyrin-sensitized solar cells has been improved intensively by the enhanced light absorption. Actually, some push--pull-type porphyrins have disclosed a remarkably high power conversion efficiency (6--7%) that was close to that of the ruthenium complexes. Phthalocyanines exhibit strong absorption around 300 and 700 nm and redox features that are similar to porphyrins. Moreover, phthalocyanines are transparent over a large region of the visible spectrum, thereby enabling the possibility of using them as ``photovoltaic windows''. However, the cell performance was poor, owing to strong aggregation and lack of directionality in the excited state. Novel unsymmetrical zinc phthalocyanine sensitizers with ``push'' and ``pull'' groups have made it possible to reduce the aggregation on a TiO2 surface, tune the level of the excited state, and strengthen the electronic coupling between the phthalocyanine core and the TiO2 surface. As a result, the power conversion efficiency of up to 3.5% has been achieved. Perylenes are well-known as chemically, thermally, and photophysically stable dyes and have been used in various optical devices and applications. Nevertheless, the power conversion efficiency remained low compared to other organic dyes. The origin of such limited cell performance is the poor electron-donating abilities of the perylenes, which makes it difficult to inject electrons from the excited singlet state of the perylenes to the conduction band of the TiO2 electrode efficiently. Strongly electron-donating perylene carboxylic acid derivatives with amine substituents at their perylene core have allowed us to increase the power conversion efficiency of up to ∼7% in perylene-sensitized solar cells. The efficiency of large π-aromatic molecule-sensitized solar cells could be improved significantly if the dyes with larger red and near-infrared absorption could be developed. }, author = {Imahori, Hiroshi and Umeyama, Tomokazu and Ito, Seigo}, date-added = {2013-12-17 08:28:59 +0000}, date-modified = {2018-06-14 10:21:20 +0000}, doi = {10.1021/ar900034t}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ar900034t}, journal = {Acc.

The cells were characterized by several techniques, including spectral response measurements, photovoltage decay transients, intensity modulated photovoltage spectroscopy (IMVS), and charge extraction. The differences in apparent electron lifetime observed for cells fabricated using the three dyes are attributed in part to changes in the surface dipole potential at the TiO2/spiro-MeOTAD interface, which shift the TiO2 conduction band energy relative to the Fermi level of the HTM. These energy shifts influence both the open circuit voltage (as a result of changes in free electron density) and the short circuit current (as a consequence of changes in the overlap between the dye LUMO level and the conduction band). A self-consistent approach was used to derive the positions of the conduction band relative to the spiro-MeOTAD redox Fermi level for cells fabricated using the three dyes. The analysis also provided estimates of the free electron lifetime in spiro-MeOTAD cells. In order to evaluate the possible contribution of the adsorbed dyes to the observed changes in surface dipole potential, their dipole moments were estimated using ab initio density functional theory (DFT) calculations. Comparison of the calculated dipole contributions with the experimentally measured shifts in conduction band energy revealed that other factors such as proton adsorption may be predominant in determining the surface dipole potential. }, author = {Howie, Wendy H. and Claeyssens, Frederik and Miura, Hidetoshi and Peter, Laurence M.}, date-added = {2013-12-17 08:28:21 +0000}, date-modified = {2013-12-17 08:28:30 +0000}, doi = {10.1021/ja076525+}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ja076525%2B}, journal = {J.

In particular, they should be designed to control the electron-transfer processes that ensure efficient dye-regeneration and prevent undesired electron recombination. In this article, the electronic and steric properties of a fluorene donor are engineered to meet all these requirements. This elegant donor is featured along with a cyclopentadithiophene bridge and a cyanoacrylic acid acceptor in JF419. A thorough comparison with Y123 and C218 demonstrates the relevance of the design. Relative to conventional donors, the fluorene construct described here enhances the light-harvesting properties, because of its exceptional electron-donating character. The functionalities used to induce the electronic push through the D--π--A structure also provide the dye with favorable steric properties. Indeed, the substitution around the fluorene core adequately insulates the TiO2 surface from the electrolyte, which prevents back-recombination and prolongs the electron lifetime in the semiconductor. Furthermore, compared to analogous dyes, JF419 maintains nearly quantitative regeneration efficiency, despite the lower regeneration driving force. The root of this observation is contributed to a significantly more delocalized hole in the photo-oxidized JF419* +, which is highlighted through transient absorption spectroscopy and quantum chemical calculations. The design principles established are relevant to the development of more comprehensive sensitizers, as evidenced by the 10.3% efficiency obtained in cobalt-based liquid dye-sensitized solar cells. }, author = {Yella, Aswani and Humphry-Baker, Robin and Curchod, Basile F.

The SM8 model may be combined with density functional theory or Hartree-Fock theory to describe a solute's electronic structure and its self-consistent-field polarization by a solvent. A key feature is the use of class IV charge models to obtain accurate charge distributions (either in the vapor phase or in solution), even when using small basis sets that are affordable for large systems. A second key feature is that nonelectrostatic effects due to cavity formation, dispersion interactions, and changes in solvent structure are included in terms of empirical atomic surface tensions that depend on geometry but do not require atom-type assignments by the user. Use of an analytic surface area algorithm provides very stable energy gradients that allow geometry optimization in solution. The SM8 continuum model, the culmination of a series of SMx models (x = 1-8), permits the modeling of such diverse media as aqueous and organic solvents, soils, lipid bilayers, and air-water interfaces. In addition to predicting accurate transfer free energies between gaseous and condensed phases or between two different condensed phases, SMx models have been useful for predicting the significant influence of condensed phases on processes associated with a change in molecular charge, including acid/base equilibria and oxidation/reduction processes. In this Account, we provide an overview of the algorithms associated with the computation of free energies of solvation in the SM8 model.

TPA--donor dyes are a class of promising organic dyes for use in dye-sensitized solar cells (DSSCs). The three dyes studied here are among the smallest of these molecules and provide important insight into the entire series of TPA dyes that are being explored as possible sensitizers in titania-based DSSCs. An attempt to calculate the optical spectra for these dyes within the B3LYP approximation to the exchange correlation functional produces erroneous results. However, Coulomb attenuated approximation (CAM-B3LYP) captures the correct photophysics of the dyes and produces more accurate charge-transfer excitation energies of their complexes with titania. This work shows that the extent to which a given approximation fails or succeeds to correctly predict the charge-transfer excitation energies in the isolated dyes is propagated in that it fails (or succeeds) to correctly predict the values of the excitation energies for the complexes. It is, therefore, important to determine the most appropriate functional for a dye before considering it in more complicated structures such as dye--titania complexes. }, author = {Dev, Pratibha and Agrawal, Saurabh and English, Niall J.}, date-added = {2013-11-25 19:05:14 +0000}, date-modified = {2013-11-25 19:05:23 +0000}, doi = {10.1021/jp306153e}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp306153e}, journal = {J.

As a result, the computed absorption and emission spectra of the incorporated dyes are red-shifted compared to those in toluene, in perfect agreement with experimental measurements. The computed electronic spectra reproduce well both the solvatochromic and Stokes shifts of the dye molecule in toluene and MCM-41, and also, the band-shape can be reconstructed by simply including the vibrational fine structure associated to the electronic transition. }, author = {Pedone, Alfonso and Bloino, Julien and Barone, Vincenzo}, date-added = {2013-11-25 17:40:37 +0000}, date-modified = {2015-03-18 13:54:09 +0000}, doi = {10.1021/jp305294u}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp305294u}, journal = {J.

Enhancement of Raman modes centered on the acceptor unit when a Raman excitation wavelength is coincident with lowest energy electronic excitation suggests that the excitation involves charge transfer from the carbazole donor to the varying benzodiazole acceptors. The pattern of the enhancement when the excitation wavelength is coincident with the higher energy transition indicates that this transition is π to π* in nature; this is consistent with TD-DFT calculations. Nanosecond transient absorption studies show long-lived excited state signals for PCDTBT (126 $\pm$ 4 ns and 1.56 $\pm$ 0.1 μs) and PCBSe (1.82 $\pm$ 0.1 μs), suggesting that population of the triplet state is appreciable. No transient signal could be detected in PCBT. B3LYP TD-DFT calculations of the monomer through to the hexamer indicate a broadly delocalized excited state orbital for PCDTBT as indicated by the linear decrease in excitation energy with an increased number of repeat units, while for PCBSe and PCBT, the reduction in excitation is sublinear. The highest occupied (HOMO) and lowest unoccupied molecular orbitals (LUMO) of PCBSe and PCBT polymers compared to PCDTBT are similarly diffuse, but the population of higher order orbitals is decreased when compared with PCDTBT. CAM-B3LYP calculations reduce the delocalization of the frontier orbitals and show less reduction in excitation energy with additional repeat units for each polymer. }, author = {Reish, Matthew E. and Nam, Sanghun and Lee, Wonho and Woo, Han Young and Gordon, Keith C.}, date-added = {2013-11-25 13:26:21 +0000}, date-modified = {2013-11-25 13:26:30 +0000}, doi = {10.1021/jp307552z}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp307552z}, journal = {J.

The energies of the excited states have been calculated with time-dependent density functional theory (TDDFT) and with the approximate coupled cluster singles and doubles (CC2) method. The geometries of porphine and quinone have been optimized with B3LYP. The influence of the external electric field on the PQ complex has been studied at six different intermolecular distances between 2.5 and 5.0 {\AA} with the BH&HLYP functional. An external electric field clearly affects the orbitals localized mostly on quinone but not the orbitals localized on porphine. Additionally, the effect of the external field increases with the increasing intermolecular distance. The optical absorption spectrum of porphine obtained by using the BH&HLYP functional is consistent with the Gouterman model and with the spectrum previously calculated with CAM-B3LYP. The potential energy curves of the Q and B states and the lowest charge transfer (CT) states of the PQ complex calculated by using the BH&HLYP with TDDFT functional have also been compared with those obtained with the CC2 method. Both methods show that the lowest CT state is clearly above the Q states when no external field is applied. Therefore, when the Q states of a porphine--quinone system are excited, the conical intersection is not possible and cannot thus provide a path for electron transfer (ET). The calculations show that the Q and B states are affected by the field much less than the lowest CT state. Consequently, the calculations show that the CT state crosses the Q and B states at certain field strengths. Thus, it is possible that the external electric field triggers ET in porphine--quinone systems via conical intersection. }, author = {Aittala, Pekka J. and Cramariuc, Oana and Hukka, Terttu I.}, date-added = {2013-11-25 13:24:14 +0000}, date-modified = {2013-11-25 13:24:28 +0000}, doi = {10.1021/ct9003417}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct9003417}, journal = {J.

A benchmark evaluation on different time-dependent density functional theory (TDDFT) approaches with respect to high-level correlated coupled cluster (CC) and multireference perturbation theory (MRPT) benchmark calculations is performed in the gas phase. The benchmark results indicate that TDDFT calculations using the hybrid MPW1K and the long-range correct CAM-B3LYP functionals represent a valuable tool of comparable accuracy to that of the much more computationally demanding ab initio methods. Thus, the problem of the comparison between the calculated excitation energies and the measured absorption maximum wavelengths has been addressed employing the MPW1K functional and including the solvation effects by a polarizable continuum model. The present results show that taking into account the chemical and physical phenomena occurring in solution (i.e., protonation/deprotonation of the carboxylic function and the explicit solute--solvent interactions) is of crucial importance for a meaningful comparison between the calculated and the experimental absorption spectra. Our investigation paves the way to the reliable computational design and predictive screening of organic dye sensitizers, even before their synthesis, in analogy to what has been achieved for transition-metal complexes. }, author = {Pastore, Mariachiara and Mosconi, Edoardo and De Angelis, Filippo and Gr{\"a}tzel, Michael}, date-added = {2013-11-25 12:29:29 +0000}, date-modified = {2013-11-25 12:29:41 +0000}, doi = {10.1021/jp100713r}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp100713r}, journal = {J.

On the basis of the well-known pitfalls of TD-DFT, its values can be then associated to the functional performances in reproducing different type of transitions and allow for the definition of a ``trust radius'' for GGA and hybrid functionals.

The predicted absorption wavelengths agree to within 5 nm with experiment, thus confirming the accuracy of the calculational level and modeling done. In both proteins, it was found that the adiabatic electronic state with the largest oscillator strength at the Franck--Condon region was not the one from which fluorescence could occur in the products. A diabatization procedure was used to determine an approximate photoactive state, based on selecting the state with the largest oscillator strength throughout. For LSSmKate1, this led to a rather flat potential energy profile but still did not predict a minimum in the product side. It is suggested that relaxation processes, absent from the model, could bring about such a minimum. LSSmKate2, on the other hand, clearly displays a favorable exoergic process in the photoactive state, and its double-proton transfer can be described as concerted but highly asynchronous, involving a barrier in the transfer of the first proton.

Our theoretical analysis discloses that the diketo isomer is the most stable one in the ground state of indigo but not in leucoindigo where the dienol minimum is more stable. Single and double proton transfer processes are not energetically favored in the ground electronic state but a single proton transfer gives a more stable tautomer in the excited electronic state of indigo whereas a double proton transfer is energetically favorable in the excited state of leucoindigo. The internal rotations are not thermodynamically allowed except for the keto-enol tautomer where a full rotation of the inter-ring C-C bond leads to another stable keto-enol structure. A preliminary analysis of the plausible conical intersections for both indigo and leucoindigo allows the discussion of the likely deactivation paths that will follow light irradiation.

For indigo the proton transfer can only take place through tunneling so the main deactivation path would involve a conical intersection accessed directly upon internal rotation of the keto-keto tautomer. For leucoindigo a richer photochemistry is expected as the single and double proton transfer processes are energetically open. The more favorable path involves single proton transfer followed by a trans to cis isomerization and a second proton transfer. This process competes on equal grounds with several non-radiative decays through conical intersections. All these results are in agreement with the experimental facts known to date.}, author = {Moreno, Miquel and Ortiz-Sanchez, Juan Manuel and Gelabert, Ricard and Lluch, Jose M.}, date-added = {2013-11-21 15:02:08 +0000}, date-modified = {2013-11-21 15:02:12 +0000}, doi = {10.1039/C3CP52763H}, issue = {46}, journal = {Phys.

SA has a twisted structure at the energetic minimum of the ground state, but ESIPT is assumed to take place through a planar structure, although this has not been fully established. The TRPES studies revealed that the excited-state dynamics within the S1 band varied significantly with excitation wavelength. At finite temperatures, the ground state was found to sample a broad range of torsional angles, from planar to twisted. At lower photon energies (370 nm), only the planar ground-state molecules were excited, and the excited-state reaction took place within 50 fs. At higher energies (350 and 330 nm), predominantly twisted ground-state molecules were excited: they had to planarize before ESIPT could occur. This process was found to be slower in methylated SA but did not change significantly in the brominated and nitrated SAs. These substitution effects on the decay dynamics can be explained by modifications of the potential barriers, as predicted by the TDDFT calculations, and support the mechanism of a twisting motion of the anilino ring prior to ESIPT.

Static investigation of stationary points and scans of the ππ* and nπ* energy surfaces have been performed. These calculations show that the concerted diproton transfer in S1 proceeds along a ridge thus making this process highly unlikely since it will stabilize toward the unsymmetrical monoproton transfer. A small energy barrier of about 0.11 eV (RI-CC2 result) between the mono- and diketo structures is obtained allowing rapid continuation of the proton transfer to the diketo form. On-the-fly dynamics simulations performed at the RI-CC2 level confirm this picture. The first proton transfer step is so fast (7 fs) that it probably cannot be resolved by experimental techniques. Important participation of the nπ* state is predicted. The present results shed a completely new light on the interpretation of the experimental results. The simulations clearly show that what has been experimentally determined as concerted transfer is in fact a combination of two sequential proton transfers separated by a small delay below the present experimental resolution. Concerning the second step of the sequential proton transfer the dynamics calculations indicate the existence of a highly dynamic system. Both the forward and reverse reactions of a monoketo/diketo equilibrium were found within the 300 fs period of the simulation. Environmental effects will certainly lead to a substantial cooling of the initially hot molecule and a concomitant decrease in the monoketo/diketo conversion rates, which will result in the experimentally observed overall time scale of 10 ps for the second proton transfer step. }, author = {Plasser, Felix and Barbatti, Mario and Aquino, Adelia J.

The recently synthesized 2-hydroxy-substituted isomer (OHBDI) shows an entirely different photochemical behavior experimentally, since it mainly undergoes ultrafast intramolecular excited-state proton transfer, followed by S1 → S0 decay and ground-state reverse hydrogen transfer. We have chosen 4-(2-hydroxybenzylidene)-1H-imidazol-5(4H)-one (OHBI) to model the gas-phase photodynamics of such 2-hydroxy-substituted chromophores. We first use various electronic structure methods (DFT, TDDFT, CC2, DFT/MRCI, OM2/MRCI) to explore the S0 and S1 potential energy surfaces of OHBI and to locate the relevant minima, transition state, and minimum-energy conical intersection. These static calculations suggest the following decay mechanism: upon photoexcitation to the S1 state, an ultrafast adiabatic charge-transfer induced excited-state intramolecular proton transfer (ESIPT) occurs that leads to the S1 minimum-energy structure. Nearby, there is a S1/S0 minimum-energy conical intersection that allows for an efficient nonadiabatic S1 → S0 internal conversion, which is followed by a fast ground-state reverse hydrogen transfer (GSHT). This mechanism is verified by semiempirical OM2/MRCI surface-hopping dynamics simulations, in which the successive ESIPT-GSTH processes are observed, but without cis--trans isomerization (which is a minor path experimentally with less than 5% yield). These gas-phase simulations of OHBI give an estimated first-order decay time of 476 fs for the S1 state, which is larger but of the same order as the experimental values measured for OHBDI in solution: 270 fs in CH3CN and 230 fs in CH2Cl2. The differences between the photoinduced processes of the 2- and 4-hydroxy-substituted chromophores are attributed to the presence or absence of intramolecular hydrogen bonding between the two rings. }, author = {Cui, Ganglong and Lan, Zhenggang and Thiel, Walter}, date-added = {2013-11-21 14:33:03 +0000}, date-modified = {2013-11-21 14:33:09 +0000}, doi = {10.1021/ja208496s}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ja208496s}, journal = {J.

It focuses particularly on an atomistic picture of the electron-injection dynamics. The interface offers an excellent case study, pertinent as well to a variety of other photovoltaic systems, photo- and electrochemistry, molecular electronics, analytical detection, photography, and quantum confinement devices. The differences between chemists' and physicists' models for describing molecules and bulk materials, respectively, create challenges for the characterization of interfaces that include both of these components. We give an overall picture of the interface by starting with a description of the properties of the chromophores and semiconductor separately, and then by discussing the coupled system, including the chromophore-semiconductor binding, electronic structure, and electron-injection dynamics. Explicit time-dependent modeling is particularly valuable for an understanding of the ultrafast electron injection because it shows a variety of individual injection events with well-defined dynamical features that cannot be made apparent by an average reaction-rate description. }, author = {Duncan, Walter R. and Prezhdo, Oleg V.}, date-added = {2013-11-18 14:15:45 +0000}, date-modified = {2018-06-14 10:21:49 +0000}, doi = {10.1146/annurev.physchem.58.052306.144054}, eprint = {http://www.annualreviews.org/doi/pdf/10.1146/annurev.physchem.58.052306.144054}, journal = {Ann.

In general, the TDDFT approach provides a more accurate description of both visible and ultraviolet regions of the UV--vis and magnetic circular dichroism (MCD) spectra of PcZn in comparison to the more popular semiempirical ZINDO/S and PM3 methods. It was found that the calculated vertical excitation energies of PcZn correlate with the amount of Hartree--Fock exchange involved in the exchange-correlation functional. The correlation was explained on the basis of the calculated difference in energy between occupied and unoccupied molecular orbitals. The influence of PcZn geometry, optimized using different exchange-correlation functionals, on the calculated vertical excitation energies in PcZn was found to be relatively small. The influence of solvents on the calculated vertical excitation energies in PcZn was considered for the first time using a polarized continuum model TDDFT (PCM-TDDFT) method and was found to be relatively small in excellent agreement with the experimental data. For all tested TDDFT and PCM-TDDFT cases, an assignment of the Q-band as an almost pure a1u (HOMO) → eg (LUMO) transition, initially suggested by Gouterman, was confirmed. Pure exchange-correlation functionals indicate the presence of six 1Eu states in the B-band region of the UV--vis spectrum of PcZn, while hybrid exchange-correlation functionals predict only five 1Eu states for the same energy envelope. The first two symmetry-forbidden n → π* transitions were predicted in the Q0-2 region and in the low-energy tail of the B-band, while the first two symmetry-allowed n → π* transitions were found within the B-band energy envelope when pure exchange-correlation functionals were used for TDDFT calculations. The presence of a symmetry-forbidden but vibronically allowed n → π* transition in the Q0-2 spectral envelope explains the long-time controversy between the experimentally observed low-intensity transition in the Q0-2 region and previous semiempirical and TDDFT calculations, which were unable to predict any electronic transitions in this area. To prove the conceptual possibility of the presence of several degenerate 1Eu states in the B-band region of PcZn, room-temperature UV--vis and MCD spectra of zinc tetra-tert-butylphthalocyanine (PctZn) in non-coordinating solvents were recorded and analyzed using band deconvolution analysis. It was found that the B-band region of the UV--vis and MCD spectra of PctZn can be easily deconvoluted using six MCD Faraday A-terms and two MCD Faraday B-terms with energies close to those predicted by TDDFT calculations for 1Eu and 1A2u excited states, respectively. Such a good agreement between theory and experiment clearly indicates the possibility of employing a TDDFT approach for the accurate prediction of vertical excitation energies in phthalocyanines within a large energy range. }, author = {Nemykin, Victor N. and Hadt, Ryan G. and Belosludov, Rodion V. and Mizuseki, Hiroshi and Kawazoe, Yoshiyuki}, date-added = {2013-11-16 14:05:12 +0000}, date-modified = {2013-11-16 14:05:22 +0000}, doi = {10.1021/jp0759731}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp0759731}, journal = {J.

It was found that, in the 2- and 2,7-derivatives, there was little influence on the S2 ← S0 excitation, which is described as ``pyrene-like'', and a strong influence on the S1 ← S0 excitation, which is described as ``substituent-influenced''. In contrast, the 1-substituted derivatives display a strong influence on both the S1 ← S0 and the S2 ← S0 excitations. These observations are rationalized by considering the nature of the orbitals involved in the transitions. The existence of a nodal plane passing through the 2- and 7-positions, perpendicular to the molecular plane in the HOMO and LUMO of pyrene, largely accounts for the different behavior of derivatives substituted at the 2- and 2,7-positions. Herein, we report the photophysical properties of a series of 2-R-pyrenes {R = C3H6CO2H (1), Bpin (2; pin = OCMe2CMe2O), OC3H6CO2H (3), O(CH2)12Br (4), C≡CPh (5), C6H4-4-CO2Me (6), C6H4-4-B(Mes)2 (7), B(Mes)2 (8)} and 2,7-R2-pyrenes {R = Bpin (9), OH (10), C≡C(TMS) (11), C≡CPh (12), C≡C-C6H4-4-B(Mes)2 (13), C≡C-C6H4-4-NMe2 (14), C6H4-4-CO2C8H17 (15), N(Ph)-C6H4-4-OMe (16)} whose syntheses are reported elsewhere.

For all derivatives, modest (0.19) to high (0.93) fluorescence quantum yields were observed. For the 2- and 2,7-derivatives, fluorescence lifetimes exceeding 16 ns were measured, with most being ca. 50--80 ns. The 4-(pyren-2-yl)butyric acid derivative (1) has a long fluorescence lifetime of 622 ns, significantly longer than that of the commercially available 4-(pyren-1-yl)butyric acid (17). In addition to measurements of absorption and emission spectra and fluorescence quantum yields and lifetimes, time-dependent density functional theory calculations using the B3LYP and CAM-B3LYP functionals were also performed.

The spectroscopic ππ* states, responsible for the optical properties of the sensors, are described within an accuracy of 0.1 eV. Similar accuracy is demonstrated in the nπ* states. The ππ* states can be assigned as a charge transfer from the aromatic π orbital localized in the azo-phenol moiety to the antibonding π* of the azo group.

Upon substitution in the phenyl moiety, red- or blue-shifts of the UV--visible bands are observed depending on whether the substituent is electron-donor or -withdrawing, respectively.

The ring system is easily rearranged to the trans-endo-fused bicyclic 6-membered lactone dimer (yellow). Both lactones can be singly or doubly amidated with primary amines leading to further colour changes. The nature of the core heterocycle (exo- vs. endo-; 5- or 6-membered ring){,} core heteroatom (O vs. N) and additional substituents on the phenyl ring allows for exquisite control over colour achievable within a single dye family. Herein we present a detailed investigation of the modelling of the electronic spectra of the Pechmann dye family by time-dependent density functional theory (TDDFT). Whereas pure Hartree-Fock (TDHF) ab-initio calculation underestimates the UV/Vis absorption maximum{,} pure TDDFT leads to a large overestimation.

Among the tested factors are technical and structural aspects as well as effects of neighboring residues and exciton couplings in the chlorophyll network. By employing a subsystem time-dependent density functional theory (TDDFT) approach based on the frozen density embedding (FDE) method we are able to determine site energies and electronic couplings separately in a systematic way. This approach allows us to treat much larger systems in a quantum chemical way than would be feasible with a conventional density functional theory. Based on this method{,} we have simulated a series of mutagenesis experiments to investigate the effect of a lack of one pigment in the chlorophyll network on the excitation properties of the other pigments. From these calculations{,} we can conclude that conformational changes within the chlorophyll molecules{,} direct interactions with neighboring residues{,} and interactions with other chlorophyll pigments can lead to non-negligible changes in excitation energies. All of these factors are important when site energies shall be calculated with high accuracy. Moreover{,} the redistribution of the oscillator strengths due to exciton coupling has a large impact on the calculated absorption spectra. This indicates that modeling mutagenesis experiments requires us to consider the entire set of chlorophyll molecules in the wild type and in the mutant{,} rather than just considering the missing chlorophyll pigment. An analysis of the mixing of particular excitations and the coupling elements in the FDEc calculation indicates that some pigments in the chlorophyll network act as bridges which mediate the interaction between other pigments.

Using a recently developed GW code based on Gaussian basis functions, we benchmark a wide range of starting points for perturbative GW, including Hartree--Fock, LDA, PBE, PBE0, B3LYP, HSE06, BH&HLYP, CAM-B3LYP, and tuned CAM-B3LYP. In the evaluation of the ionization energy, the hybrid functionals are clearly superior results starting points when compared to Hartree--Fock, to LDA, or to the semilocal approximations. Furthermore, among the hybrid functionals, the ones with the highest proportion of exact-exchange usually perform best. Finally, the reliability of the frozen-core approximation, that allows for a considerable speed-up of the calculations, is demonstrated. }, author = {Bruneval, Fabien and Marques, Miguel A.

Variations of the bond-length alternation obtained with different optimized structures produce small differences of the excitation energy in the limit of an infinite chain. Hybrid functionals with range-separated exchange are optimally `tuned', which is shown to minimize the delocalization error (DE) in the cyanine π systems. Much unlike the case of charge-transfer excitations, small DEs are not strongly correlated with better performance. A representative cyanine is analyzed in detail. Compared with accurate benchmark data, TDDFT with `pure' local functionals gives too high singlet excitation energies for all systems, but DFT-based ΔSCF calculations with a local functional severely underestimates the energies. TDDFT strongly overestimates the difference between singlet and triplet excitation energies. An analysis points to systematically much too small magnitudes of integrals from the DFT components of the exchange-correlation response kernel as the likely culprit. The findings support previous suggestions that the differential correlation energy between the ground and excited state is not correctly produced by TDDFT with most functionals. }, author = {Moore II, Barry and Autschbach, Jochen}, date-added = {2013-11-06 13:54:23 +0000}, date-modified = {2013-12-06 10:33:34 +0000}, doi = {10.1021/ct400649r}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct400649r}, journal = {J.

Here, a software program (Cyclaplex) has been developed to determine the number, identity (including isomers), and relative amounts of linear and cyclic architectures from a given number and ratio of reacting monomers.

The program can be applied to cyclic peptides, cycloveratrylenes, cyclens, calixarenes, cyclodextrins, crown ethers, cucurbiturils, annulenes, expanded meso-substituted porphyrin(ogen)s, and diverse supramolecular (e.g., protein) assemblies.

Although all the compounds show faint dual emission (Φ ≈ 0.01), which is assigned to the normal and excited-state intramolecular proton transfer (ESIPT) fluorescence in a fluid solution, they generally display efficient ESIPT fluorescence (Φ up to 0.6) in a polymer matrix. The introduction of electron-donating and electron-withdrawing groups into the phenyl ring causes blue and red shifts of the ESIPT fluorescence emission band, respectively. On the other hand, the introduction of such groups into the imidazopyridine part results in fluorescence shifts in the opposite directions. The results of ab initio quantum chemical calculations of the intramolecular proton-transferred (IPT) state are well in line with the ESIPT fluorescence energies. The plots of the calculated highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels against the Hammett substituent constants (σ) show good linearity with different slopes, which can rationalize the effect of the substituent and its position on the IPT state. Therefore, we have developed a series of HPIPs as new ESIPT fluorescent compounds and demonstrate that ESIPT fluorescence properties would be rationally tuned using quantum chemical methods. }, author = {Mutai, Toshiki and Sawatani, Hirotaka and Shida, Toshihide and Shono, Hideaki and Araki, Koji}, date-added = {2013-09-23 14:29:20 +0000}, date-modified = {2013-09-23 14:29:28 +0000}, doi = {10.1021/jo302711t}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jo302711t}, journal = {J.

Two new S1--TICT states, stable in ethanol and cyclohexane, were found for HBI and its amino derivatives; they are twisted and pyramidalized. The flat PES of the ICT process makes the S1--TICT states accessible. The S1--TICT state is effective for radiationless relaxation, which is responsible for quenching the fluorescence of the S1--Tsyn state. In contrast to the situation encountered conventionally, the S1--TICT state does not possess a critically larger dipole moment than its precursor, S1--Tsyn state; hence, it is not particularly stable in polar solvents.

In the anti-enol isomer, the phenyl hydroxyl group appears to not interact strongly with solvent but rather forms a strong intramolecular hydrogen bond with the benzoxazole oxygen atom. In the syn-enol isomer, the phenyl hydroxyl proton may interact with solvent or form an internal hydrogen bond with the benzoxazole nitrogen atom. Upon excitation, the proton is transferred from the oxygen atom to the nitrogen atom of the internally hydrogen bonded syn-enol isomer in 170 fs, regardless of the solvent. The lifetime of the resulting excited keto tautomer is solvent dependent and on the order of picoseconds.

The best performing polymer material was subjected to lifetime studies in four different atmospheres (dry nitrogen, dry oxygen, humid nitrogen and the ambient atmosphere). The best stability was observed in nitrogen while the devices showed nearly the same degree of stability in dry oxygen. In both the ambient atmosphere and the humid nitrogen atmospheres the devices degraded quickly. Finally the stability was compared with two other polymer systems that are known to give stable devices, poly(3-hexylthiophene) (P3HT) and native polythiophene (PT) obtained from the thermocleavable poly(3-(2-methylhexyloxycarbonyl)dithiophene) (P3MHOCT).

A common approach to tuning these parameters is to modify the structure of conjugated polymers by copolymerizing with different units. In this paper, research work focuses on the synthesis of benzo[1,2-b:4,5-b′]dithiophene (BDT) with different conjugated units and their photovoltaic performance. Eight new BDT-based polymers with commonly used conjugated units, including thiophene, benzo[c][1,2,5]thiadiazole (BT), thieno[3,4-b]pyrazine (TPZ), etc., were synthesized. The bandgaps of the polymers were tuned in the range of 1.0--2.0 eV, and their HOMO and LUMO energy levels could also be tuned effectively. The absorption spectra as well as electrochemical and photovoltaic properties of these polymers were investigated systematically. Some units exhibiting the same effect of bandgap lowering exhibited different effects on molecular energy levels of the polymers. For example, the TPZ unit can reduce the bandgap by lowering the LUMO energy level and elevating the HOMO level of the polymer, but the BT unit can lower the bandgap only by depressing the LUMO level. Since open-circuit voltage (Voc) of the heterojunction polymer solar cell is believed to be inversely proportional to the HOMO level of electron donor material, Voc of the devices based on H9, the copolymer of BDT and TPZ, was ca. 0.5 V lower than that of the device based on H7, the copolymer of BDT and BT. The effects of seven commonly used units on bandgap, molecular energy level, and photovoltaic properties of the BDT based polymers are studied and discussed in this paper, which can provide a guideline not only for design of photovoltaic materials but also for materials of various other electronic devices. In addition, the PCE of the device based on PCBM and H6, one of the BDT-based polymers, reached 1.6%, and Voc, Isc, and FF of the device were 0.75 V, 3.8 mA/cm2, and 56%, respectively, which indicates that BDT is a promising common unit for photovoltaic conjugated polymers. Since we have developed the synthetic method of the 4,8-bisalkoxy-BDT monomer, the BDT unit will play an important role in future research on conjugated polymer design. }, author = {Hou, Jianhui and Park, Mi-Hyae and Zhang, Shaoqing and Yao, Yan and Chen, Li-Min and Li, Juo-Hao and Yang, Yang}, date-added = {2013-07-01 13:15:06 +0000}, date-modified = {2013-07-01 13:19:30 +0000}, doi = {10.1021/ma800820r}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ma800820r}, journal = {Macromolecules}, number = {16}, pages = {6012-6018}, title = {Bandgap and Molecular Energy Level Control of Conjugated Polymer Photovoltaic Materials Based on Benzo[1,2-b:4,5-b′]dithiophene}, url = {http://pubs.acs.org/doi/abs/10.1021/ma800820r}, volume = {41}, year = {2008}, bdsk-url-1 = {http://pubs.acs.org/doi/abs/10.1021/ma800820r}, bdsk-url-2 = {http://dx.doi.org/10.1021/ma800820r}} @article{Bar05d, abstract = {In the last few years, thiophene-based materials, which are semiconductor and fluorescent compounds, have become a highly interdisciplinary field of research, with diverse studies ranging from the fabrication of electronic and optoelectronic devices to the selective detection of biopolymers.

Polymeric bulk-heterojunction (BHJ) PVCs, whose photoactive layer is composed of a blend of bicontinuous and interpenetrating donors and acceptors, can maximize interfacial area between the donor and the acceptor. Classic polymer donors, such as dialkoxy-substituted poly(para-phenylene vinylene)s (PPVs) and poly(3-hexylthiophene) (P3HT), have been widely investigated. However, advances in synthetic methodology provide new avenues for the development of novel conjugated polymer donors with improved power conversion efficiencies.

This Account primarily focuses on novel donor polymers that have shown power conversion efficiencies greater than 1%. 2,1,3-Benzothiadiazole, thiophene, thieno[3,4-b]pyrazine, quinoxaline, and silole have emerged as useful heterocycles for constructing a variety of conjugated polymers for photovoltaic applications. We summarize useful information, such as molecular weights, absorption, bandgap, energy levels, and their photovoltaic performances with detailed device parameters (see comparison tables), about these novel donor polymers.

Despite the use of its characteristic spectroscopic features for identification, the theoretical basis of the unique UV--visible absorbance spectrum of μ-[Fe(III)PPIX]2O has not been explored. To investigate this and to establish a structural and spectroscopic model for Fe(III)PPIX species, density functional theory (DFT) calculations were undertaken for H2O--Fe(III)PPIX and μ-[Fe(III)PPIX]2O. The models agreed with related Fe(III)porphyrin crystal structures and reproduced vibrational spectra well. The UV--visible absorbance spectra of H2O--Fe(III)PPIX and μ-[Fe(III)PPIX]2O were calculated using time-dependent DFT and reproduced major features of the experimental spectra of both. Transitions contributing to calculated excitations have been identified. The features of the electronic spectrum calculated for μ-[Fe(III)PPIX]2O were attributed to delocalization of electron density between the two porphyrin rings of the dimer, the weaker ligand field of the axial ligand, and antiferromagnetic coupling of the Fe(III) centers. Room temperature magnetic circular dichroism (MCD) spectra have been recorded and are shown to be useful in distinguishing between these two Fe(III)PPIX species. Bands underlying major spectroscopic features were identified through simultaneous deconvolution of UV--visible and MCD spectra. Computed UV--visible spectra were compared to deconvoluted spectra. Interpretation of the prominent bands of H2O--Fe(III)PPIX largely conforms to previous literature. Owing to the weak paramagnetism of μ-[Fe(III)PPIX]2O at room temperature and the larger number of underlying excitations, interpretation of its experimental UV--visible spectrum was necessarily tentative. Nonetheless, comparison with the calculated spectra of antiferromagnetically coupled and paramagnetic forms of the μ-oxo dimer of Fe(III)porphine suggested that the composition of the Soret band involves a mixture of π→π* and π→dπ charge transfer transitions. The Q-band and charge transfer bands appear to amalgamate into a mixed low energy envelope consisting of excitations with heavily admixed π→π* and charge transfer transitions. }, author = {Kuter, David and Venter, Gerhard A. and Naidoo, Kevin J. and Egan, Timothy J.}, date-added = {2013-04-17 08:32:14 +0000}, date-modified = {2013-04-17 08:32:25 +0000}, doi = {10.1021/ic301154e}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ic301154e}, journal = {Inorg.

These dyes were synthesized very simply and exhibited intense NIR emission in the solid state. Complexation with boron was shown to impart very strong donor--acceptor character into the excited state of these dyes, which further shifted their emission towards the NIR region (up to 855 nm for dye 5 b, which contained the strongly donating triphenylamine group). Strikingly, these optical features were obtained for crystalline solids, which are characterized by high molecular order and tight packing, two features that are conventionally believed to be detrimental to luminescence in organic crystals. Remarkably, the emission of light from the π-stacked molecules did not occur at the expense of the emission quantum yield. Indeed, in the case of pyrene-containing dye 4, for example, a fluorescence quantum yield of about 15 % with a fluorescence emission maximum at 755 nm were obtained in the solid state. Moreover, dye 3 a and acetonaphthone-based compounds 1 b, 2 b, and 3 b showed no evidence of degradation as solutions in CH2Cl2 that contained EtOH. In particular, solutions of brightly fluorescent compound 3 a (brightness: ε×Φf=45 000 M--1 cm--1) could be stored for long periods without any detectable changes in its optical properties.

Within both methods, the excitation energies strongly depend on the employed equilibrium structures, whose differences can be rationalized in terms of bond length alternation indexes. It is shown that functionals with an increased amount of exact exchange provide the best estimation of the ground and excited state properties. While B3LYP fails to predict the excitation energies due to its intrinsic problems in describing charge transfer (CT) states, the long-range corrected CAM-B3LYP and M06-2X functionals deliver good agreement with the experimental UV/vis absorption spectrum. The calculation of resonance Raman intensity patterns is used to discern which ground and excited state gradients are best. The results clearly evidence that both CAM-B3LYP and RASSCF excited state gradients and energies in combination with CAM-B3LYP ground state gradients are appropriate to describe the CT state of this push--pull chromophore. }, author = {Kupfer, Stephan and Guthmuller, Julien and Gonz{\'a}lez, Leticia}, date-added = {2013-01-16 10:01:44 +0000}, date-modified = {2013-01-16 10:01:58 +0000}, doi = {10.1021/ct3009057}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct3009057}, journal = {J.

Expanded porphyrins, synthetic analogues of porphyrins that contain more than 18 π electrons in the conjugated pathway, have an increased number of pyrroles or other heterocyles or multiple meso-carbon bridges. The expanded porphyrins have attracted tremendous attention because of unique features such as anion binding or transport that are not present in porphyrins. Expanded porphyrins exhibit wide applications that include their use in the coordination of large metal ions, as contrasting agents in magnetic resonance imaging (MRI), as sensitizers for photodynamic therapy (PDT) and as materials for nonlinear optical (NLO) studies. Pentaphyrin 1, sapphyrin 2, and smaragdyrin 3 are expanded porphyrins that include five pyrroles or heterocyclic rings. They differ from each other in the number of bridging carbons and direct bonds that connect the five heterocyclic rings. Sapphyrins were the first stable expanded porphyrins reported in the literature and remain one of the most extensively studied macrocycles. The strategies used to synthesize sapphyrins are well established, and these macrocycles are versatile anion binding agents. They possess rich porphyrin-like coordination chemistry and have been used in diverse applications. This Account reviews developments in smaragdyrin chemistry. Although smaragdyrins were discovered at the same time as sapphyrins, the chemistry of smaragdyrins remained underdeveloped because of synthetic difficulties and their comparative instability. Earlier efforts resulted in the isolation of stable β-substituted smaragdyrins and meso-aryl isosmaragdyrins. Recently, researchers have synthesized stable meso-aryl smaragdyrins by [3 + 2] oxidative coupling reactions. These results have stimulated renewed research interest in the exploration of these compounds for anion and cation binding, energy transfer, fluorescent sensors, and their NLO properties. Recently reported results on smaragdyrin macrocycles have set the stage for further synthetic studies to produce stable meso-aryl smaragdyrins with different inner cores to study their properties and potential for various applications. }, author = {Pareek, Yogita and Ravikanth, M. and Chandrashekar, T.

These unusual push‚{\"A}{\`\i}pull systems contain phenylene ({\^O}£{\o}1,4-C6H4{\^O}£{\o}; 1), biphenylene ({\^O}£{\o}4,4‚{\"A}≤-(1,1‚{\"A}≤-C6H4)2{\^O}£{\o}; 2), thiophene ({\^O}£{\o}2,5-C4H2S{\^O}£{\o}; 3), and dithiophene ({\^O}£{\o}5,5‚{\"A}≤-(2,2‚{\"A}≤-C4H2S)2{\^O}£{\o}; 4) as {\oe}{\"A}-conjugated bridges and different types of three-coordinate boron moieties serving as both {\oe}{\"A}-donor and {\oe}{\"A}-acceptor. Molecular structures of 2, 3, and 4 were determined by single-crystal X-ray diffraction. Photophysical studies on these systems reveal blue-green fluorescence in all compounds. The Stokes shifts for 1, 2, and 3 are notably large at 7820‚{\"A}{\`\i}9760‚{\"A}{\"O}cm‚{\`a}{\'\i}1 in THF and 5430‚{\"A}{\`\i}6210‚{\"A}{\"O}cm‚{\`a}{\'\i}1 in cyclohexane, whereas the Stokes shift for 4 is significantly smaller at 5510‚{\"A}{\"O}cm‚{\`a}{\'\i}1 in THF and 2450‚{\"A}{\"O}cm‚{\`a}{\'\i}1 in cyclohexane. Calculations on model systems 1‚{\"A}≤‚{\"A}{\`\i}4‚{\"A}≤ show the HOMO to be mainly diazaborolyl in character and the LUMO to be dominated by the empty p orbital at the boron atom of the BMes2 group. However, there are considerable dithiophene bridge contributions to both orbitals in 4‚{\"A}≤. From the experimental data and MO calculations, the {\oe}{\"A}-electron-donating strength of the 1,3-diethyl-1,3,2-benzodiazaborolyl group was found to lie between that of methoxy and dimethylamino groups. TD-DFT calculations on 1‚{\"A}≤‚{\"A}{\`\i}4‚{\"A}≤, using B3LYP and CAM-B3LYP functionals, provide insight into the absorption and emission processes. B3LYP predicts that both the absorption and emission processes have strong charge-transfer character. CAM-B3LYP which, unlike B3LYP, contains the physics necessary to describe charge-transfer excitations, predicts only a limited amount of charge transfer upon absorption, but somewhat more upon emission. The excited-state (S1) geometries show the borolyl group to be significantly altered compared to the ground-state (S0) geometries. This borolyl group reorganization in the excited state is believed to be responsible for the large Stokes shifts in organic systems containing benzodiazaborolyl groups in these and related compounds.}, author = {Weber, Lothar and Eickhoff, Daniel and Marder, Todd B. and Fox, Mark A. and Low, Paul J. and Dwyer, Austin D. and Tozer, David J. and Schwedler, Stefanie and Brockhinke, Andreas and Stammler, Hans-Georg and Neumann, Beate}, date-added = {2012-12-04 14:43:20 +0000}, date-modified = {2012-12-04 14:43:32 +0000}, doi = {10.1002/chem.201102059}, issn = {1521-3765}, journal = {Chem.

To provide a better measure of vibrational band intensities, the spectrum was recorded by cavity ringdown absorption spectroscopy up to energies of 2000 cm--1 above the band origin in a slit jet sample. The sample rotational temperature was estimated to be about 30 K, but the vibrational temperature was higher, permitting the assignment of many vibrational hot bands. The vibronic structure of the electronic transition was simulated using a combination of time-dependent density functional theory (TD-DFT) electronic structure codes, Franck--Condon integral calculations, and a second-order vibronic model developed previously [Johnson, P. M.; Xu, H. F.; Sears, T. J. J. Chem. Phys.2006, 125, 164331]. The density functional theory (DFT) functionals B3LYP, CAM-B3LYP, and LC-BLYP were explored. The long-range-corrected functionals, CAM-B3LYP and LC-BLYP, produced better values for the equilibrium geometry transition moment, but overemphasized the vibronic coupling for some normal modes, while B3LYP provided better-balanced vibronic coupling but a poor equilibrium transition moment. Enlarging the basis set made very little difference. The cavity ringdown measurements show that earlier intensities derived from resonance-enhanced multiphoton ionization (REMPI) spectra have relative intensity errors. }, author = {Lopez, Gary V. and Chang, Chih-Hsuan and Johnson, Philip M. and Hall, Gregory E. and Sears, Trevor J. and Markiewicz, Beatrice and Milan, Mariana and Teslja, Alexey}, date-added = {2012-12-04 12:53:42 +0000}, date-modified = {2012-12-04 12:54:05 +0000}, doi = {10.1021/jp302936h}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp302936h}, journal = {J.

The simulated TD-B2PLYP spectra are compared to experiment and those computed with the TD-B2LYP (i.e., no CIS(D) correction) and TD-B3LYP methods. Vertical excitation energies at the perturbatively corrected level are, in the majority of cases, more accurate than, e.g., with TD-B3LYP. Relative band positions are also reproduced better. In one example, the high-energy CD bands are not computed with sufficient accuracy, which is attributed to an instability of the perturbation correction. Due to the inclusion of a large portion of ``exact'' exchange (53%) in B2PLYP, the spectra feature less artificially created excited states and CD bands than with TD-B3LYP. In all six examined cases, TD-B2PLYP gives qualitatively correct spectra, whereas the hybrid functionals sometimes show a more erratic behavior. Therefore, we can recommend the use of the new double-hybrid approach for the computation of CD and the prediction of absolute configurations of chiral molecules. }, author = {Goerigk, Lars and Grimme, Stefan}, date-added = {2012-12-03 18:25:09 +0000}, date-modified = {2012-12-03 18:25:28 +0000}, doi = {10.1021/jp807366r}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp807366r}, journal = {J.

In this implementation we use the resolution-of-the-identity approximation for the two-electron repulsion integrals to reduce the computational cost. To avoid storage of large arrays we introduce in addition a numerical Laplace transformation of orbital energy denominators for the response of the doubles amplitudes. The error due to the numerical Laplace transformation is found to be negligible. Using this new implementation{,} we performed a series of benchmark calculations on substituted benzene and azobenzene derivatives to get reference values for TD-DFT results.

By comparing the isolated CPEI molecule and the molecule-in-cluster, we show that the molecular packing through intermolecular hydrogen-bonding interactions can hinder the excited-state nonradiative decay and thus enhance the fluorescence efficiency in the solid phase. Aggregation effect is shown to block the nonradiative decay process through hindering the low-frequency vibration motions. The fluorescence quantum yields for both isolated molecule and aggregation are predicted to be insensitive to temperature due to the hydrogen-bonding nature, and their values at room temperature are consistent with the experiment. }, author = {Wu, Qunyan and Peng, Qian and Niu, Yingli and Gao, Xing and Shuai, Zhigang}, date-added = {2012-11-11 11:17:33 +0000}, date-modified = {2012-11-11 11:17:33 +0000}, doi = {10.1021/jp3002367}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/jp3002367}, journal = {J.

Here{,} we review quantum-chemical approaches for modeling such phenomena. In particular{,} embedding methods can be particularly useful for treating localized excitations in complex chemical systems. These split the total system into a number of interacting subsystems. The electronic excitations processes occurring in the subsystem of interest are then treated with high accuracy{,} while its environment is taken into account in a more approximate way. In this review{,} we use a formulation based on the formally exact frozen-density embedding theory as our starting point. This provides a common framework for discussing the different embedding approaches that are currently available. Moreover{,} it also forms the basis of emerging methods that allow for a seamless coupling of density-functional theory and wavefunction based approaches{,} both for ground and excited states.

These experimental GBs are compared with those calculated (for the two sites of protonation in the case of nicotine and nornicotine) at the B3LYP/6-311+G(3df,2p)//B3LYP/6-31G(d,p) level, or those estimated from substituent effects on the GBs of 2-substituted pyrrolidines, 2-substituted N-methylpyrrolidines, and 3-substituted pyridines. It is found that, in contrast to the Nsp3 protonation in water, in the gas phase nornicotine is protonated on the pyridine nitrogen, because the effects of an intramolecular CH···Nsp3 hydrogen bond and of the polarizability of the 3-(pyrrolidin-2-yl) substituent add up on the Nsp2 basicity, while the polarizability effect of the 2-(3-pyridyl) substituent on the Nsp3 basicity is canceled by its field/inductive electron-withdrawing effect. The same structural effects operate on the Nsp3 and Nsp2 basicities of nicotine, but here, the polarizability effect of the methyl group puts the pyrrolidine nitrogen basicity very close to that of pyridine. Consequently, protonated nicotine is a mixture of the Nsp3 and Nsp2 protonated forms. }, author = {Graton, J{\'e}r{\^o}me and Berthelot, Michel and Gal, Jean-Fran{\c c}ois and Girard, Sandrine and Laurence, Christian and Lebreton, Jacques and Le Questel, Jean-Yves and Maria, Pierre-Charles and Nau{\v s}, Petr}, date-added = {2012-09-04 13:18:08 +0200}, date-modified = {2012-09-04 13:18:21 +0200}, doi = {10.1021/ja017770a}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ja017770a}, journal = {J.

The nature of the substituents allows modulation of the fluorescence from 650 to 780 nm. Replacement of the fluoro ligands by ethynyl-aryl or ethyl residues is facile using Grignard reagents. Several X-ray molecular structures have been determined, allowing establishment of structure--fluorescence relationships. When the steric crowding around the boron center is severe, the aromatic substituents α to the diisoindolomethene nitrogens are twisted out of coplanarity, and hypsochromic shifts are observed in the absorption and emission spectra. This shift reached 91 nm with ethyl substituents compared to fluoro groups. When ethynyl linkers are used, the core remains flat, and a bathochromic shift is observed. All the fluorophores exhibit relatively high quantum yields for emitters in the 650--800 nm region. When perylene or pyrene residues are connected to the dyes, almost quantitative energy transfer from them to the dye core occurs, providing large virtual Stokes shifts spanning from 8000 to 13 000 cm--1 depending on the nature of the dye. All the dyes are redox active, providing the Bodipy radical cation and anion in a reversible manner. Stepwise reduction or oxidation to the dication and dianion is feasible at higher potentials.

The major challenge is the effective management of the electron-donor strength of the substitution pattern, in order to modulate the emission of these novel dyes over a wide spectral range (430--500 nm). A direct relationship between the electron-donor character of the substituent and the extension of the spectral hypsochromic shift is seen through the energy increase of the LUMO state. However, when the electron-donor character of the substituent is high enough, an intramolecular charge-transfer process appears to decrease the fluorescence ability of these dyes, especially in polar media. Some of the reported novel BODIPY dyes provide very high fluorescence quantum yields, close to unity, and large Stokes shifts, leading to highly efficient tunable dye lasers in the blue part of the spectrum; this so far remains an unexploited region with BODIPYs. In fact, under demanding transversal pumping conditions, the new dyes lase with unexpectedly high lasing efficiencies of up to 63 %, and also show high photostabilities, outperforming the laser action of other dyes considered as benchmarks in the same spectral region.

Unusually, the fullerene core is a poor electron acceptor and does not enter into light-induced electron-transfer reactions with the appended dyes, but ineffective electronic energy transfer from the excited-state dye to the C60 residue competes with fluorescence from the yellow dye. Intraparticle electronic energy transfer from yellow to blue dyes can be followed by steady-state and time-resolved fluorescence spectroscopy and by excitation spectra for isolated C60 nanoparticles dissolved in dioxane at 293 K and at 77 K. The decorated particles can be loaded into polymer films by spin coating from solution. In the dried film, efficient energy transfer occurs such that photons absorbed by the yellow dye are emitted by the blue dye. Films can also be prepared to contain C60 nanoparticles loaded with the yellow Bodipy dye but lacking the blue dye and, under these circumstances, electronic energy migration occurs between yellow dyes appended to the same nanoparticle and, at higher loading, to dye molecules on nearby particles. Doping these latter polymer films with the mixed-dye nanoparticle coalesces these multifarious processes in a single system. Thus, long-range energy migration occurs among yellow dyes attached to different particles before trapping at a blue dye. In this respect, the film resembles the natural photosynthetic light-harvesting complexes, albeit at much reduced efficacy. The decorated nanoparticles sensitize amorphous silicon photocells. }, author = {Lehl, Julien and Nierengarten, Jean-Fran{\c c}ois and Harriman, Anthony and Bura, Thomas and Ziessel, Raymond}, date-added = {2012-07-09 19:37:48 +0200}, date-modified = {2012-07-09 19:38:10 +0200}, doi = {10.1021/ja206894z}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ja206894z}, journal = {J.

The adoption of NIR imaging is also growing rapidly due to the availability of targeted biological agents for diagnosis and basic medical research that can be imaged in vivo. The wavelength range of 650--1450 nm falls in the region of the spectrum with the lowest absorption in tissue and therefore enables the deepest tissue penetration. This is the wavelength range we focus on with this review. To operate effectively, the imaging agents must both be excited and must emit in this long-wavelength window. We review the agents used for imaging by absorption, scattering, and excitation (such as fluorescence). Imaging agents comprise both aqueous soluble and insoluble species, both organic and inorganic, and unimolecular and supramolecular constructs. The interest in multimodal imaging, which involves delivery of actives, targeting, and imaging, requires nanoparticles or supramolecular assemblies. Nanoparticles for diagnostics also have advantages in increasing circulation time and increased imaging brightness relative to single molecule imaging agents. This has led to rapid advances in nanocarriers for long-wavelength, NIR imaging. }, author = {Pansare, Vikram J. and Hejazi, Shahram and Faenza, William J. and Prud'homme, Robert K.}, date-added = {2012-07-09 19:09:12 +0200}, date-modified = {2012-07-09 19:09:27 +0200}, doi = {10.1021/cm2028367}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/cm2028367}, journal = {Chem.

Each case is studied with 11 or 13 density functionals. For comparison, the accuracy of the all-electron def2-TZVP basis set is tested with both relativistic and nonrelativistic treatments. Convergence and accuracy are assessed by comparing to relativistic all-electron calculations with a nearly complete relativistic basis set (NCBS-DK, which denotes the cc-pV5Z-DK basis set for 3d metals and hydrogen and the ma-cc-pV5Z-DK basis set for oxygen) and to nonrelativistic all-electron calculations with a nearly complete nonrelativistic basis set (NCBS-NR, which denotes the cc-pV5Z basis set for 3d metals and hydrogen and the ma-cc-pV5Z basis set for oxygen). As compared to NCBS-DK results, all ECP calculations perform worse than def2-TZVP all-electron relativistic calculations when averaged over all 130 data (13 functionals and ten test cases). The compact effective potential (CEP) relativistic effective core potential (RECP) combined with a valence basis set developed for the many-electron Dirac--Fock (MDF10) RECP performs best in effective core potential calculations and has an average basis-set incompleteness error of 3.7 kcal/mol, which is much larger than that (0.9 kcal/mol) of def2-TZVP relativistic all-electron results. Hence, the def2-TZVP relativistic all-electron calculations are recommended for accurate DFT calculations on 3d transition metals. In addition to our general findings, we observed that all kinds of density functionals do not show the same trends. For example, when ECPs are used with hybrid functionals, which sometimes are not recommended for calculations of transition metal systems, they are found to perform better at achieving the basis-set limit than when used with local functionals and meta-GGA functionals. The most successful combination of RECP and basis set has a basis-set incompleteness error of 1.7--2.4 kcal/mol for hybrid generalized gradient approximations, which is smaller than that of nonrelativistic NCBS calculations (whose average basis-set incompleteness error for hybrid functionals is 2.7--2.9 kcal/mol). The average basis-set incompleteness error in Hartree--Fock calculations is 1.0--4.4 kcal/mol for five of the ECP basis sets but is 5.8--10.8 kcal/mol for six others. }, author = {Xu, Xuefei and Truhlar, Donald G.}, date-added = {2012-04-27 13:47:03 +0200}, date-modified = {2012-04-27 13:47:18 +0200}, journal = {J.

In the P-1 system{,} one uses the triphenylamine moiety as the electron donor{,} malononitrile as the electron acceptor{,} and a thiophene that plays the role of the conjugated chain. Basically{,} the difference between the P-1 dye and the common organic dyes used in the n-type DSSC field is the anchoring group located on the electron donor group. In a first step{,} DFT and TDDFT approaches have been exploited to calculate the key parameters controlling both the intramolecular charge transfer (ICT) and hole transfer rate constants in the Gurney-Gerischer-Marcus (GGM) formalism{,} for either a solvent-controlled adiabatic or a nonadiabatic electron transfer. These are: (i) the electronic coupling; (ii) the reorganization energies; and (iii) the variation of the Gibbs energy. The gathered results are in agreement with the experimental trends. (i) The vertical ICT excited states energy has been calculated at 2.67 eV{,} in perfect line with the experiment (2.65 eV). (ii) Two mechanisms can be conceived for the hole transfer and regeneration process. The first deals with the reduction of dye molecule at the excited state followed by an electron transfer from the reduced dye to the oxidized regenerator. The second implies a redox reaction between the excited dye and the oxidized regenerator{,} followed by an electron transfer from the cathode to the oxidized dye. (iii) Our theoretical investigation suggests that the first mechanism is dominant. Secondly{,} we propose structural modifications improving the TPA-based DSSCs hole transfer efficiency and we show that an additional -CN graft on the malononitrile unit combined to the functionalisation of the TPA moieties by -OMe groups (to give P-1b) should significantly improve the key parameters related to the electron injection. Indeed{,} for P-1b{,} we have noticed an increase of both the RLHE factor (0.907) and the injection driving force (-0.33 eV).

As a reference state for the electron, we have chosen the electron at 0 K, which is the one used in computational chemistry. Unlike almost all previous estimations of SHE, ΔGaq⊖(H+) was used instead of the real potential, αaq(H+). This choice was made to obtain a SHE value based on the chemical potential, which is the appropriate reference to be used in theoretical computations of standard reduction potentials. The result of this new estimation is a value of 4.281 V for the absolute potential of SHE. The problem of conversion of standard reduction potentials (SRPs) measured or estimated in water to the corresponding values in nonaqeuous solvents has also been addressed. In fact, thermochemical cycles are often used to calculate SRPs in water versus SHE, and it is extremely important to have conversion factors enabling estimation of SRPs in nonaqueous solvents.

It is shown that dehydroindigo readily converts into its neutral keto form, the blue indigo, in a process which depends on the solvent and water content of the medium. DHI was investigated in toluene, in benzene, and in methanol and it was found that both the oxidized and the keto indigo forms are present in solution. In marked contrast to what has been found for keto-indigo, where the internal conversion channel dominates >99% of the excited state deactivation, or with the fully reduced leuco-indigo, where fluorescence, internal conversion, and singlet-to-triplet intersystem crossing coexist, in the case of DHI in toluene and benzene, the dominant excited state deactivation channel involves the triplet state. Triplet state yields (ϕT) of 70--80%, with negligible fluorescence (≤0.01%) are observed in these solvents. In methanol the ϕT value decreases to ∼15%, with an increase of the fluorescence quantum yield to 2%, which makes these processes competitive with the S1 ⇝ S0 internal conversion deactivation process. The data are experimentally compatible with the existence of a lowest lying singlet excited state of n,π* origin in toluene and of π,π* origin in methanol. A time-resolved investigation in the picosecond time domain suggests that the emission of DHI involves three interconnected species (involving rotational isomerism), with relative contributions depending on the emission wavelength. DFT calculations (B3LYP 6-31G** level) were performed in order to characterize the electronic ground (S0) and excited singlet (S1) and triplet (T1) states of DHI. The HOMO--LUMO transition was found to accompany an n → π* transition of the oxygen nonbonding orbitals to the central CC and adjacent C--N bonds. Calculations also revealed that in S0 the two indole-like moieties deviate from planarity from ca. 20$\,^{\circ}$, whereas in S1 and T1 the predicted structure is basically planar; a gradual decrease of the carbon--carbon central bond distance is seen in the order S0, S1, T1. An additional study on the blue pigment Maya Blue was made, and the comparison between the solid-state spectra of indigo, DHI, and Maya Blue suggests that, in line with recent investigations, DHI is present together with indigo in Maya Blue.

With the keto form of this dye, fluorescence (φF = 0.76) and intersystem crossing (φT = 0.11) are dominant, whereas with indigo, efficient internal conversion (φIC = 0.99) is observed, probably involving proton transfer through intramolecular hydrogen bonds. With Cibalackrot, this pathway is blocked, supporting the above model for indigo. With the reduced form of Cibalackrot, more than 98% of the absorbed quanta are dissipated through S1 ∼∼→ S0 internal conversion, which contrasts with leuco-indigo, where fluorescence (φF = 0.35), internal conversion (φIC = 0.53) and intersystem crossing (φT = 0.125) are found to be competitive. In addition, a synthetic precursor of Cibalackrot (preCiba) was also investigated. This has a rigid molecular structure (with a moiety identical to Cibalackrot and the other to indigo), but intra- or intermolecular proton transfer is allowed between adjacent carbonyl and N--H groups. With this precursor in its keto structure the photophysical parameters are generally very close to those of the keto form of indigo, and different from those of Cibalackrot. A more detailed investigation of the time-decay profiles of preCiba in dioxane (and with added water and D2O) has shown that these follow biexponential laws with a shorter component of 14--25 ps, which appears associated with a risetime at longer wavelength emissions (and to a positive preexponential at shorter emission wavelengths) and a longer lived (decay) component of 104--130 ps. In the steady-state spectra of preCiba, the variation with temperature reveals a blue shift of the emission maxima, which is interpreted as the presence (simultaneous emission) of two species (keto and enol) in the excited state. Indigo and deuterated indigo are also found to present a similar behavior. The overall data are interpreted as to be due to an excited-state process involving the proton transfer between keto and enol forms. Rate constants with values of 7 × 1010 s-1 for preCiba and 1.6 × 1011 s-1 for deuterated indigo were obtained. This inverse isotope effect is justified on the basis of the proposed model for proton-transfer excited-state deactivation. }, author = {Seixas de Melo, J. and Rond{\~a}o, R. and Burrows, H.

Analogous Mg2+--dye interactions which do not strongly affect the MB visible spectrum can also be present. Thermal treatment used in the preparation of the pigment appears therefore essential to release some of the structural water molecules tightly bound to the Al3+ ions in the internal clay surface, thus leaving them available to coordinate the organic molecule.

When tested against the same set of ions that was recently used to develop the SM6 continuum solvation model, SM6 retains its previously determined high accuracy; indeed, in most cases the mean unsigned error improves when it is tested against the more accurate reference data. }, author = {Kelly, Casey P. and Cramer, Christopher J. and Truhlar, Donald G.}, date-added = {2012-04-11 08:44:16 +0200}, date-modified = {2012-04-27 09:49:54 +0200}, doi = {10.1021/jp063552y}, journal = {J.

These triazole-based multipolar chromophores have been shown to be promising candidates for two-photon absorption (TPA) transparency optimization in perspective of optical limiting in the visible region. In this work, the nature of one- and two-photon absorption properties in a family of triazole-based chromophores has been investigated using hybrid time-dependent density functional theory (TD-DFT). We use recent extensions of TD-DFT to determine nonlinear optical responses and natural transition orbitals to analyze the underlying electronic processes. Our results are also interpreted in the framework of the Frenkel exciton model. In agreement with experimental data, we found that introducing a triazole moiety into multibranched chromophores substantially modifies their optical behavior due to changes in electronic delocalization and charge-transfer properties between donating end groups and the branching center that can be controlled by the triazole ring. Structural conformations via modulation of the torsion between phenyl and triazole rings significantly alter the excited state electronic structure. Moreover, isomer positioning also greatly influences both linear and nonlinear optical responses such as TPA. Our theoretical findings allow elucidation of these differences and contribute to the general understanding of structure--property relations. Consequently, the interplay of donor/acceptor strength, triazole regioisomerism, and branching are shown to provide flexible means allowing for precise tuning of both linear and nonlinear optical responses, thus opening new perspectives toward synergic TPA architectures. }, author = {Katan, Claudine and Blanchard-Desce, Mireille and Tretiak, Sergei}, date-added = {2012-04-06 17:59:25 +0200}, date-modified = {2012-04-06 17:59:36 +0200}, doi = {10.1021/ct1004406}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct1004406}, journal = {J.

The direct covalent linkage of the ferrocenyl moiety to the meso position of the macrocycle is achieved by simple oxidative coupling of appropriate precursors with trifluoroacetic acid as catalyst. The electronic coupling between the ferrocenyl moiety and the macrocyclic π system is apparent from: a) the red shifts (293--718 cm--1) of the Soret and Q-bands in the electronic absorption spectra of ferrocenyl conjugates; b) the shift of oxidation potentials (50--130 mV) of both the ferrocene and the corrole rings to the positive potentials; and c) considerable shortening of the CC bond which connects the ferrocene and the meso-carbon atom of the macrocycle. The single-crystal X-ray structure of oxasmaragdyrin--ferrocene conjugate 9 reveals the planarity of the 22π skeleton with very small deviations of the meso-carbon atoms. The meso-ferrocenyl substituent has a small dihedral angle of 38$\,^{\circ}$, making way for mixing of the molecular orbitals of the ferrocene and the macrocycle.

Our synthetic strategy involves linking the azobenzene group in one of the precursors to a dipyrromethane subunit, which was achieved by reaction of azobenzenecarbaldehyde with pyrrole under TFA catalysis. A [3+2] acid-catalyzed oxidative coupling of this precursor with the tripyrrane moiety gave the expected smaragdyrin--azobenzene conjugates. The azobenzene is in the (E) conformation both in the precursor and in the smaragdyrin conjugates, as revealed by its single-crystal X-ray structure. Electronic absorption and emission spectral studies reveal the presence of a moderate electronic interaction between the azobenzene and smaragdyrin π-systems. Irradiation experiments at 360 nm reveal the presence of a reversible (E)/(Z) transformation of the azobenzene moiety in the precursors 3b and 4b. However, in the smaragdyrin conjugates the formation of the (Z) conformer leads to the decomposition of the macrocycle upon prolonged irradiation. Excitation at the azobenzene absorption results in the appearance of the emission band of smaragdyrin, thereby suggesting an energy transfer. The electrochemical data reveal that ring oxidations of the smaragdyrin macrocycle become harder upon azobenzene introduction, which suggests the electron-withdrawing nature of the azobenzene in these conjugates. A significant shortening of the N--N bond (0.067 {\AA}) and elongation of the C--N bonds (0.055 and 0.069 {\AA}) in 7a relative to the azobenzene--dipyrromethane precursor 4a clearly reveal a rearrangement of the electronic π-delocalization pathway in the smaragdyrin--azobenzene conjugates.

The three dyads were freely soluble in common organic solvents and characterized by MS, NMR, absorption, electrochemical, and fluorescence techniques. The NMR, absorption, and electrochemical studies indicated that the two macrocycles in the dyads interact weakly with each other and maintain their independent characteristic features. The steady-state fluorescence studies of the dyads showed that the thiasapphyrin and thiarubyrin units are nonfluorescent but fluorescence was observed from the BF2--oxasmaragdyrin unit. However, the quantum yield of the BF2--oxasmaragdyrin unit in the dyads was less than that of monomeric BF2--oxasmaragdyrin because of an enhancement of nonradiative decay channels operating in the dyads. The potential use of two of the three dyads containing the BF2--smaragdyrin subunit as fluorescent sensors for anions was explored. The studies showed that the binding of the anion at the protonated sapphyrin and rubyrin sites in the respective dyads can be followed by the clear changes in the fluorescence band of the BF2--oxasmaragdyrin unit, which indicates that these dyads can be used as fluorescent anion sensors.}, author = {Pareek, Yogita and Ravikanth, M.}, date-added = {2012-04-02 14:31:21 +0200}, date-modified = {2012-04-02 14:31:34 +0200}, doi = {10.1002/ejoc.201100652}, issn = {1099-0690}, journal = {Eur.

The synthetic strategy involved a [3 + 2] acid-catalyzed oxidative coupling reaction of the appropriate dipyrromethane and oxatripyrrane. The desired meso substituents, such as phenylacetylenylphenyl and the ferrocenes, were incorporated to the dipyrromethane unit prior to the oxidative coupling reaction. The optical absorption, emission characteristics, and the quantum yield of the smaragdyrin conjugates depends on the nature of the substituent, nature of linker group, and the spacer length. Theoretical studies at the DFT level suggest high delocalization of electrons confined to only four of the five available heterocyclic rings for the free bases. However, upon Rh(I) metalation, the π-electron delocalization is extended to all the heterocyclic rings. The two-photon absorption cross section (TPA) values σ(2) measured through the open aperture Z-scan method, increases linearly with enhanced π-electron delocalization for the smaragdyrins containing phenylacetylene substituents. The meta branching of substituents decreases σ(2) values. Introduction of Rh(I) to the smaragdyrin cavity enhances the σ(2) values by about 3--10 orders of magnitude, attributed to the increased aromatic character upon Rh(I) insertion. The calculated molecular electrostatic potential (MESP) and harmonic oscillator model of aromaticity (HOMA) for the free bases and the Rh(I) derivatives justifies such a conclusion. A linear correlation observed for the second oxidation potential of Rh(I) derivatives and corresponding free bases also support the increased aromaticity upon Rh(I) insertion. The electrochemical data for ferrocene-containing smaragdyrins reveal easier ring oxidation by about 50--130 mV and harder ferrocene oxidation by 40--180 mV suggesting electron-donating nature of the ferrocene upon linking with the smaragdyrin π system. The TPA cross section value of 88782 GM observed for 5g represents one of the highest values known for a metalloexpanded porphyrin derivative. }, author = {Misra, Rajneesh and Kumar, Rajeev and Chandrashekar, Tavarekere K. and Suresh, C.

Preliminary and new electrochemical results have revealed a strongly negative solvatochromic charge transfer (CT) absorption due to a S0 [rightward arrow] S2 vertical transition and a weakly-solvatochromic emission due to S1 [rightward arrow] S0 transition.

To investigate these issues, the explicit dependence of excitation energies on exact exchange is quantified for four representative molecules, paying attention to the effect of constant, short-range, and long-range contributions. A stability analysis is used to verify that the problematic TDDFT triplet excitations can be understood in terms of the ground state triplet instability problem, and it is proposed that a Hartree--Fock stability analysis should be used to identify triplet excitations for which the presence of exact exchange in the TDDFT functional is undesirable. The use of the Tamm--Dancoff approximation (TDA) significantly improves the problematic triplet excitation energies, recovering the correct state ordering in benzoquinone; it also affects the corresponding singlet states, recovering the correct state ordering in naphthalene.

To investigate the influence of nonlocal exact orbital (Hartree--Fock) exchange on the shape of the potential energy surface of the S1 state in detail, it has been computed along the twisting coordinate employing the standard BP86, B3LYP, and BHLYP xc-functionals as well as the long-range separated (LRS) exchange-correlation (xc)-functionals LC-BOP, ωB97X, ωPBE, and CAM-B3LYP and compared to RI-CC2 benchmark results. Additionally, a recently suggested Λ-parameter has been employed that measures the amount of CT in an excited state by calculating the spatial overlap of the occupied and virtual molecular orbitals involved in the transition. Here, the error in the calculated S1 potential energy curves at BP86, B3LYP, and BHLYP can be clearly related to the Λ-parameter, i.e., to the extent of charge transfer. Additionally, it is demonstrated that the CT problem is largely alleviated when the BHLYP xc-functional is employed, although it still exhibits a weak tendency to underestimate the energy of CT states. The situation improves drastically when LRS-functionals are employed within TDDFT excited state calculations. All tested LRS-functionals give qualitatively the correct potential energy curves of the energetically lowest excited states of P. Y. 101 along the twisting coordinate. While LC-BOP and ωB97X overcorrect the CT problem and now tend to give too large excitation energies compared to other non-CT states, ωPBE and CAM-B3LYP are in excellent agreement with the RI-CC2 results, with respect to both the correct shape of the potential energy curve as well as the absolute values of the calculated excitation energies. }, author = {Pl\"otner, J{\"u}rgen and Tozer, David J. and Dreuw, Andreas}, date-added = {2012-03-22 08:36:42 +0100}, date-modified = {2012-03-22 08:37:46 +0100}, doi = {10.1021/ct1001973}, eprint = {http://pubs.acs.org/doi/pdf/10.1021/ct1001973}, journal = {J.

All four sensitizers have been fully characterized using ATR-FTIR, UV--vis, and CV. These sensitizers were tested in DSSCs using 0.05 M I2, 0.5 M 1,2-dimethyl-3-n-propylimidazolium iodide (DMPI), and 0.5 M lithium iodide (LiI) in methoxypropionitrile (MPN) redox electrolyte. The sensitizers having a monocarboxylic acid group, i.e., M1 and M2, have shown marginally higher IPCE and efficiency than M3 and M4 having dicarboxylic acid groups. To have a detailed understanding of this behavior, the adsorption and binding energies to the TiO2 surface of these dyes have been investigated using computational techniques (periodic DFT).

Here we present quantum chemical {[}(time-dependent) density functional theory ((TD-)DFT)] calculations for vibrational spectra of riboflavin, the parent molecule of biological blue-light receptor chromophores, in its electronic ground (S-0) and lowest singlet excited states (S-1). Further, vibronic absorption spectra for the S-0 -> S-1 transition and vibronic emission spectra for the reverse process are calculated, both including mode mixing. Solvent effects are partially accounted for by using a polarizable continuum model (PCM) or a conductor-like screening model (COSMO). Calculated vibrational and electronic spectra are in good agreement with measured ones and help to assign the experimental signals arising from photoexcitation of flavins. In particular, upon photoexcitation a loss of double bond character in the polar region of the ring system is observed which leads to vibronic fine structure in the electronic spectra.

SS and conventional linear response (LR) models have been compared by computing the emission energies for different benchmark systems (formaldehyde in water and three coumarin derivatives in ethanol). Special attention is given to the influence of dynamical solvation effects on LR geometry optimizations in solution. The results on formaldehyde point out the complementarity of LR and SS approaches and the advantages of the latter model especially for polar solvents and/or weak transitions. The computed emission energies for coumarin derivatives are very close to their experimental counterparts, pointing out the importance of a proper treatment of nonequilibrium solvent effects on both the excited and the ground state energies.

The fluorescence quantum yields, fluorescence lifetimes, radiative rate constants, nonradiative rate constants and absorption and fluorescence spectral characteristics show unusual deviations in the lower polarity aprotic solvents in comparison to those in other aprotic solvents of medium to higher polarities. The results indicate that the dye exists in different structural forms in the lower and in the medium to higher polarity solvents. Drawing an analogy with the results reported for other amino-substituted dyes, it is inferred that 2,6-DAAQ dye adopts a planar intramolecular charge transfer (ICT) structure in medium to higher polarity solvents, where the amino lone pairs are in good resonance with the anthraquinone pi-cloud. In the lower polarity solvents, however, the dye is inferred to exist in a nonplanar structure where the amino lone pairs are not in good resonance with the anthraquinone pi-cloud. Due to these structural differences, the dye displays significantly different photophysical behavior in the lower polarity solvents than in the other solvents of medium to higher polarities. Supportive evidence for the above structural changes has been obtained from ab initio quantum chemical calculations on the structures of the dye under different conditions. Unusual deviations in the photophysical properties of 2,6-DAAQ dye in protic solvents in comparison to those in aprotic solvents of similar polarities are attributed to the intermolecular hydrogen bonding effect involving the OH groups of the protic solvents and the quinonoid oxygens of the dye.

Other lead compounds (4f and 4g) exhibit broad antibacterial activity including MRSA and vancomycin-resistant Enterococcus faecalis (VRE) that is comparable to other commercially available cationic antiseptic chemicals. This unique difference in antibacterial profile may pave the way for the development of new therapeutic agents. (C) 2010 Elsevier Ltd.

Ring-necked pheasants (Phasianus colchicus) can cause localized damage to newly planted sunflower, and blackbirds (Icterids) damage ripening sunflower annually in the United States of America. We conducted seed germination experiments, a repellent efficacy study with ring-necked pheasants and Avipel (R) repellent (a.i. 50\% 9,10-anthraquinone), and laboratory and field efficacy studies with common grackles (Quiscalus quiscula) and Avipel (R)-treated confectionery sunflower. Compared to the germination of seeds not treated with anthraquinone, we observed no negative effects of up to 12,223 ppm, 14,104 ppm, and 11,569 ppm anthraquinone seed treatments for germination of confectionery sunflower, oilseed sunflower, and canola seeds, respectively. Pheasants avoided emergent sunflower seedlings (12 days post-planting) from 15,800 ppm anthraquinone seed treatments during a caged preference test (P = 0.045). We observed a positive concentration-response relationship (P = 0.001) and predicted a threshold concentration (i.e., 80\% repellency) of 9200 ppm anthraquinone for common grackles offered Avipel (R)-treated confectionery sunflower seeds. Grackles also reliably discriminated between untreated sunflower and seeds treated with 1300 ppm anthraquinone in captivity (P < 0.001). During our field efficacy study for ripening confectionery sunflower, we observed 18\% damage among anthraquinone-treated enclosures and 64\% damage among untreated enclosures populated with common grackles (P < 0.001). Harvested seed mass averaged 2.54 kg (dry weight) among treated enclosures and 1.24 kg among untreated enclosures (P < 0.001). Our laboratory and field efficacy data provide a reliable basis for planning future field applications of anthraquinone-based repellents for protection of sunflower crops. Supplemental field efficacy studies are necessary for development of an effective avian repellent and management of avian depredation of ripening agricultural crops, including oilseed sunflower.

Studies on the effect of scan rate on the conductivity of the copolymer film confirmed the formation of a stable conducting copolymer film. The FTIR spectrum recorded for the copolymer film provides concrete evidence of copolymer formation, since it indicates the presence of quinone units in the copolymer backbone. XRD data (particle size: 47 nm) and SEM (grain size: 100 nm) micrographs provide a clear picture of the nano-sized polymeric particles formed.

These dyes are classifiable into three types from the viewpoint of correlations between thermal properties and solubilities. The first group consists of hardly soluble anthraquinone dyes with the same phenylthio groups at positions 1 and 5. They have large enthalpy of fusions (94-127 kg/kJ) which induce strong interactions among dye molecules. The second group consists of dyes with two different phenylthio groups at positions 1 and 5. They have smaller enthalpy of fusions (around 60 kg/kJ) and can be solved in the cases of some combinations of phenylthio groups. The third group consists of dyes with two different phenylthio groups and one of them has a trifluoromethyl group at a meta position. They have very low enthalpy of fusions (2.8-22.8 kg/kJ) and their solubilities are very large even at low temperatures. The difference between the solubility in fluorinated liquid crystals and in fluorinated solvents suggests that dyes in liquid crystal phase have specific solvation forms that are different from those in isotropic phase.}}, address = {{4 PARK SQUARE, MILTON PARK, ABINGDON OX14 4RN, OXON, ENGLAND}}, affiliation = {{Iwanaga, H (Reprint Author), Toshiba Co Ltd, Corp Res \& Dev Ctr, Kawasaki, Kanagawa 210, Japan. {[}Iwanaga, Hiroki; Aiga, Fumihiko] Toshiba Co Ltd, Corp Res \& Dev Ctr, Kawasaki, Kanagawa 210, Japan.}}, author = {Iwanaga, Hiroki and Aiga, Fumihiko}, author-email = {{hiroki.iwanaga@toshiba.co.jp}}, date-added = {2011-03-08 15:57:41 +0100}, date-modified = {2011-03-08 15:59:17 +0100}, doc-delivery-number = {{722BT}}, doi = {{10.1080/02678292.2010.531149}}, issn = {{0267-8292}}, journal = {Liq.
