Abstract

The photosensitized electron-transfer system containing R~(bpy)~~+ as photosensitizer and N, N'-bis (4-sulfonatotolyl)-4, 4'-bipyridyldiylium (BSV) as quencher was investigated in aqueous solutions containing the polyelectrolyte poly (viny1 sulfate)(PVS). This is the first system where acceleration of the forward quenching reaction together with considerable retardation of the reaction regenerating the ground-state species occurs on addition of a ...
