Photoinduced Intramolecular Electron Transfer in RE(I) Chromophore-Quencher Complexes: Rate Dependence in the Inverted Region and the Use of a Rigid Organic Spacer

Rates for intramolecular electron transfer (kET) were determined in two molecular systems in which an electron donor is covalently bonded to a transition metal chromophore of the type [(diimine)ReI(CO)3L]+. In one system the dependence of kET on ΔGET was examined and in another the rates for charge separation and recombination across a rigid organic spacer were determined.
