Photoredox reactions of a positively charged water-soluble polymer containing covalently bound tris(2,2 prime -bipyridyl)ruthenium(II)-like centers: N-ethylated copolymers of 4-vinylpyridine and bis(2,2 prime -bipyridyl)(4-methyl-4 prime -vinyl-2,2 prime -bipyridyl)ruthenium(II)

The rate of electron transfer from the excited state of the (Ru(bpy){sub 3}){sup 2+}-like center in N-ethylated copolymers of 4-vinylpyridine and (Ru(bpy){sub 2}(MeVbpy)){sup 2+} to methylviologen, propylviologensulfonate, or ferric ion has been studied as a function of ionic strength bpy = 2,2{prime}-bipyridyl; MeVbpy = 4-methyl-4{prime}-vinyl-2,2{prime}-bipyridyl. The yields of Ru(III) centers and of reduced quencher have been determined directly by laser flash photolysis.
