抄録

The Electropolymerization of diphenyl compounds (p-phenoxyaniline (PA), p-phenoxyphenol (PP), 4-aminodiphenylamine (ADA) and 4-hydroxydiphenylamine (HDA)) was carried out under various electrolysis conditions, and the preparation of polymer films and their electrochemical properties and structures were examined. It was found that the electrochemical oxidation of PA, PP and ADA leads to the formation of polymer films PPA, PPP and PADA, respectively, on the electrode surfaces and that these films are elecctro-active in aqueous solutions. It became also apparent that PPA contains the redox units corresponding to azobenzene-hydrazobenzene, p-aminophenol-quinone imine and p, p′-biphenol-biphenoquinone redox couples and PPP contains those corresponding to p-benzoquinone-hydroquinone and p, p′-biphenol-biphenoquinone redox couples. PADA displayed complicated electrochemical response such as that of electroative poly-aniline films. In contrast to PA, PP and ADA, the electrochemical oxidation of HDA did not lead to the corresponding polymeric film formation.
