Tunneling Energy Effects in Photoinduced Charge and Energy Transfer

Abstract

Driving force effects on electron transfer rates in molecular donor–bridge–acceptor systems have been investigated extensively in the past. Significantly less well explored are tunneling energy effects in long-range charge transfer. These effects have to do with the energy differences between the donor/acceptor energy levels and those of the bridging molecules that are in between the two reactants. This contribution summarizes some recent advances in this research field.
