The photoinduced electron transfer quenching rate constants and the relevant activation parameters demonstrated that the hexarhenium(III) cluster acted as a useful photoredox sensitizer towards various A and the system gave a high charge separation yield owing to electrostatic repulsion between the product ions: [Re6(μ 3-S)8Cl6]3− and A −. These results were proved explicitly by nanosecond transient absorption spectroscopy.
