Abstract
The photosensitized reduction of the series of dialkyl-4,4′-bipyridinium salts, CnV2+, is examined in water-in-oil microemulsions, by using Ru(bpy)32+ as sensitizer and (NH4)3EDTA as electron donor. With the amphiphilic electron acceptors (n = 8-18) the water-in-oil microemulsion media affect the charge separation of the initial encounter cage complex, [Ru(bpy)23+⋯CnV+·], and stabilize the photoproducts, CnV+· and Ru(bpy)33+, against the recombination process. Consequently, enhanced quantum yields for CnV+· formation are observed under continuous illumination.
