Abstract
There has been a growing interest in photochemical reduction of methylviologen (1,1′-dimethyl-4,4′-dipyridinium dichloride; MV2+) as a means of solar energy conversion1–4, because the cation radical (MV+˙) can reduce protons to give hydrogen gas5. One problem in a photochemical conversion system is the effective separation of the reaction products, because a photochemical reaction in a homogeneous solution usually accompanies a spontaneous backward reaction which consumes the acquired energy. To overcome this problem, macro- or micro-heterogeneous reaction environments such as micelle6–9 or liposome1 have been proposed. A solid phase photochemical reaction must also be useful for constructing an effective photoenergy conversion system. We describe here how MV2+ adsorbed on solid cellulose could be photoreduced to give MV+˙, the colour of the cellulose changing from white to deep blue. The reaction could be sensitized by tris(bipyridyl)ruthenium(II) complex (Ru(bpy)3) and EDTA.
