Notes:
The characteristics of the photoinduced electron transfer reaction from polystyrene pendant tris(2,2′-bipyridyl)ruthenium (II) complex [Ru(bpy)32+] to methylviologen (MV2+) were studied. The rate constant k1 from the excited state of the complex, Ru(bpy)32+*, to MV2+ were determined for both the polymeric and monomeric complexes from the lifetime τ of Ru(bpy)32+* and the quenching rate of Ru(bpy)32+* by MV2+. The polymer pendant Ru(bpy)32+* showed three kinds of τ components ranging from 7 to 474 ns, in contrast to the monomeric complex, which showed one component of 350 ns. The k1 values for both complexes were almost the same, on the order of 108 L/mol s. The photoinduced electron transfer from solid-phase Ru(bpy)32+ to liquid-phase MV2+ was realized by utilizing the polymer complex, and the solid-liquid interphase reaction system is discussed.
