抄録
The photoredox ability of a hexarhenium(III) cluster, [Re-6(mu (3)-S)(8)Cl-6](4-), in acetonitrile was examined on the basis of the emission quenching experiments of the cluster by a series of neutral organic electron acceptors (A). 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: [Re-6(mu (3)-S)(8)Cl-6](3-) and A (-). These results were proved explicitly by nanosecond transient absorption spectroscopy.
