Abstract

We report a 5-fold acceleration of the backward intermolecular electron transfer between a rhodamine 800 dye molecule and N,N-dimethylaniline (DMA). This effect results from the controlled variation of the solvent dynamical properties in binary mixtures of DMA and acetonitrile. The observed acceleration reflects the competition between solvent-controlled and nonadiabatic electron transfer in the limit of barrierless reaction. A linear dependence of the electron-transfer time on the longitudinal relaxation time, as predicted by the outer sphere electron-transfer model is clearly observed.
