Photo-oxidation (photoelectrochromism) of poly(aniline) was performed using photoinduced electron transfer between Ru complex (Ru(bpy) 2+ 3) and methylviologen molecules. Especially, effect of electrode structure on the photoelectrochromism was at first analysed in solution system. The electrode structure to increase the probability that poly(aniline) and Ru(bpy) 2+ 3 came into contact or very nearly so was effective to proceed the photoelectrochromism. Further, employment of poly(ethylene glycol) (PEG, Mw=400) as additive into Flemion matrix revealed to enable the present photoelectrochromism even in all solid state. Effect of PEG addition was also discussed.
