Photo-induced Intermolecular Charge Transfer in Porphyrin Complexes
Optical excitation of the sequential supermolecule H2P −ZnP −Q induces an electron transfer from the free-base porphyrin (H2P ) to the quinone (Q) via the zinc porphyrin (ZnP ). This process is modeled by equations of motion for the reduced density matrix which are solved numerically and approximately analytically. These two solutions agree very well in a great region of parameter space. It is ...
متن کاملFrom charge transfer to electron transfer in halogen-bonded complexes of electrophilic bromocarbons with halide anions.
Experimental and computational studies of the halogen-bonded complexes, [R-Br, X(-)], of bromosubstituted electrophiles, R-Br, and halide anions, X(-), revealed that decrease of a gap between the frontier orbitals of interacting species led to reduction of the energy of the optical charge-transfer transition and to increase in the ground-state charge transfer (X(-) → R-Br) in their associates. ...
متن کاملDetermination of Trimethoprim Based on Charge-Transfer Complexes Formation
A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
متن کاملPhotochromism of a diarylethene charge-transfer complex: photochemical control of intermolecular charge-transfer interaction.
A diarylethene derivative bearing a phenylenediamine group formed radical ions with an electron acceptor molecule in solution, and the concentration of the radical ions was modulated by the photochromic reaction of the diarylethene, reflecting the difference in the electron-donating character between the open- and closed-ring isomers.
متن کاملOn the role of charge transfer in halogen bonding.
The role of charge transfer in halogen bonding is the subject of an ongoing debate and controversy. It is clear from experimental data that charge transfer occurs in halogen bonds, but its contribution to the energetics of the interaction can be evaluated only computationally. Since the charge transfer is not a physically well-defined property, there are multiple computational approaches, which...
