Abstract

In photoinduced electron-transfer systems accompanying chemical equilibrium changes, such as the formation/dissociation of a noncovalent-bonded complex, the calculation method of the charge separation and recombination reaction rates have been derived based on a simple model, in which the formation/dissociation of noncovalent bonding during the electron-transfer reaction is treated as a change of the chemical equilibrium. The effects of the formation/dissociation of noncovalent bonding on the driving forces and the reorganization energies were calculated using the chemical equilibrium constants for the reactant and product states. It has been demonstrated that the formation/dissociation of noncovalent bonding affects the electron-transfer reaction rates not only by stabilizing the charge-separated state, but also by increasing the reorganization energy.
