Abstract:

A charge transfer (CT) complex was synthesized using electron donor 2-amino aniline (AA) and electron acceptor 2,5-dihydroxy benzoquinone (DHBQ) in an acetonitrile medium. The charge transfer complex stoichiometry is 1:1. The Benesi-Hildebrand equation was used to determine the molar absorptivity (εCT), association constant (KCT) and other physical constants. The synthesized solid CT-complex was analyzed by 1H NMR and FT-IR spectroscopic methods. DFT study of the CT complex (gas phase) at the basis set B3LYP/6-31++G also gave similar results of the experimental work. Mulliken atomic charges an

Abstract:

In the current study, a direct method was used to synthesize a new series of charge-transfer complex compounds. Reaction of different quinones with 3,4-selenadiazo benzophenone in a 1:1 mole ratio by acetonitrile gave a unique charge-transfer complex compound in a good yield. All compounds were characterized by UV-Vis, FTIR, 1H-NMR, and 13C-NMR. The analysis findings agreed with the produced compound’s proposed chemical structures.

From the electron-phonon coupling strength at T = 0 K values of the charge-transfer (CT) character in the range between 6% and 10% are calculated. The differences in these values are found to be correlated with the energetic positions of the triplet state, which are explained within the framework of the Mulliken theory.

Abstract:

Since the discovery of metallic conductivity in the TTF-TCNQ complex, the charge transfer (CT) complex materials have been studied for such properties as semiconductivity or superconductivity. The synthesis of new CT materials using trimeric perfluoro-ortho-phenylene mercury (Hg3) as electron acceptor compound was done first by Haneline and Gabaï [1]. A series of studies of CT materials containing Hg3 and tetrathiafulvalene (TTF) or dithieno thiophene (DTT) as an electron donor compounds was carried out by different methods. Co-crystalzation with TTF gave a larger variety of co-crystals than w

Abstract:

Boron containing π-electron chromophores represented by tri(9-anthryl)borane show quite unique spectroscopic and photophysical properties, owing to the presence of the vacant p-orbital on the boron atom. In practice, we demonstrated that the excited states of arylborane derivatives were characterized by charge transfer from the π-orbital of the aryl group to the vacant p-orbital on the boron atom: π(Ar) – p(B) CT. If such π(Ar) – p(B) CT interactions are introduced to the MLCT excited state of a transition metal complex, new and novel aspects into photophysics of the metal complexes could be d

Abstract:

An electron donor–acceptor supramolecular complex was formed between an anionic zinc chlorin carboxylate ( ZnCh -) and lithium-ion-encapsulated [60]fullerene ( Li +@ C 60) by an electrostatic interaction in benzonitrile ( PhCN ). Photoinduced electron transfer in the supramolecular complex of ZnCh -/ Li +@ C 60 resulted in the formation of the charge-separated state via electron transfer from the triplet excited state of ZnCh - to Li +@ C 60. We report herein photovoltaic cells using ZnCh -/ Li +@ C 60 nanoclusters, which are assembled on the optically transparent electrode (OTE) of nanostruct

Abstract:

The molecular charge transfer reactions of quinine (Q) with 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) as a π-acceptor to form charge transfer (CT) complexes have been studied. The CT complexes were characterized by infrared spectra, NMR, mass spectrometry, conductometry and spectrometry. The Q-DDQ and Q-TCNQ charge transfer complexes were monitored at 480 and 843 nm, respectively. The results confirm the formation of CT complexes. The molar ratio of Q:DDQ and Q: TCNQ assessed using Job’s method was 1:1, which agrees with the results obtained by t

The electron-population degrees-of-freedom of donor-acceptor systems are reexamined and alternative simple models of charge-transfer reactivity are discussed in the substrate and atomic resolutions. The in situ differential descriptors of the polarized subsystems are emphasized and alternative energy profiles in interactions between hard and soft acidic and basic reactants are used to investigate the process representative activation and reaction energies. The intersecting-state model of such acid-base (AB) systems is explored, its predictions of the reaction transition-state complex and its p

Photoactive supramolecules composed of electron donor and electron acceptor entities are important for light energy harvesting applications. In the present study, a Star Wars Tie Fighter Ship shaped supramolecular triad was constructed by self-assembling two zinc naphthalocyanines to a fulleropyrrolidine bearing two pyridine entities using an axial coordination approach. Optical absorption and emission studies revealed stable complex formation, and the experimentally determined free-energy change revealed the possibility of electron transfer from singlet excited zinc naphthalocyanine to the fu

Through-space charge transfer (TSCT) between spatially adjacent donor and acceptor units has garnered considerable attention as a promising design principle for optoelectronic materials. While TSCT systems incorporating rigid spacers have been extensively studied to enhance through-space interactions, transition metal complexes connected by flexible linkers remain underexplored, despite increasing interest in their potential TSCT behavior.

The complex amplitudes of the electronic wavefunctions on different sites are used as Kramers variables for describing Electron Transfer. The strong coupling of the electronic charge to the many nuclei, ions, dipoles, etc, of the environment, is modeled as a thermal bath better considered classically. After elimination of the bath variables, the electron dynamics is described by a discrete nonlinear Schrödinger equation with norm preserving dissipative terms and Langevin random noises (at finite temperature). The standard Marcus results are recovered far from the inversion point, where atomic

Photosystem I (PS I) is a photosynthetic pigment–protein complex that absorbs light and uses the absorbed energy to initiate electron transfer. Electron transfer has been shown to occur concurrently along two (A- and B-) branches of reaction center (RC) cofactors. The electron transfer chain originates from a special pair of chlorophyll a molecules (P700), followed by two chlorophylls and one phylloquinone in each branch (denoted as A−1, A0, A1, respectively), converging in a single iron–sulfur complex Fx. While there is a consensus that the ultimate electron donor–acceptor pair is P700+A0−, t

The crystal structure determination of the new rhodium(III)-complex [(DML)(C5Me5)ClRh](PF6).

This result stands in contrast to the previously reported structure of a cationic dihydrobiopterin bound to [Mo(O)Cl3]- which exhibited a very unsymmetrical chelate arrangement. Chemical and electrochemical two-electron reduction of the Rh(III) complex led to a very labile Rh(I) species (DML)(C5Me5)Rh which is distinguished by an intense charge t
