Abstract

Conductive polyaniline was successfully generated when Flemion film containing tris(2,2-bipyridyl)ruthenium complex (Ru(bpy)₃²⁺) and methylviologen (MV²⁺) was illuminated in an acidic aqueous solution containing N-phenyl-p-phenylenediamine (PPD) and aniline or acetone. Aniline or acetone was employed to prepare PPD-incorporating particles in an acidic aqueous solution, which was important for the photopolymerization. The photopolymerization proceeded in the solution rather than on the film when aniline was employed at higher concentration. This is due to the release of Ru(bpy)₃²⁺ from the film by the ion-exchange reaction between Ru(bpy)₃²⁺ and protonated aniline. On the other hand, acetone molecules did not take part in the photopolymerization. Acetone enables PPD to be supplied near Ru(bpy)₃²⁺ in the film without the release of Ru(bpy)₃²⁺. Addition of acetone was revealed to be effective for the photopolymerization of aniline derivatives for the film from the viewpoint of image formation.
