SINGLE-ELECTRON TRANSFER IN ORGANIC-MOLECULES

The rate of electron transfer was studied in typical organic molecules. The approach is based on a Green's function technique which allows one to account for multiscattering electron tunneling. Quantum-chemical calculations are used to obtain the parameters of dynamical Dyson's equations for relevant double-time retarded Green's function. The parameters are used to estimate electron tunneling rate including neutral and mononegative ions of the alpha, omega-diphenylalkanes with different numbers of methyl groups. The role of bridge as the conductor of an extra electron is demonstrated from results of the calculations.
