• Behaviors of excited [Ru(bpy)<SUB>3</SUB>]<SUP>2+</SUP> bound to anionic molecular assemblies such as polymer electrolytes, vesicles and micelles together with electron-acceptor quencher MV<SUP>2+</SUP> have been investigated by measurements of [Ru(bpy)<SUB>3</SUB>]<SUP>2+</SUP> luminescence quenching and radical yields in electron-transfer quenching using a dye laser photolysis apparatus. Quenching behavior characteristic to each molecular assembly has been observed. A remarkable enhancement of quenching was observed in the presence of poly(vinyl sulfate). Such an effect was observed also in sodium dihexadecyl phosphate solution though it is less pronounced. However, no such specific quenching behavior was observed in sodium dodecyl sulfate micellar solution.
