Electroactive polymer films formed from the Schiff base product of 1,8-diaminonaphthalene and dehydroacetic acid I. Preparation and characterization

We report on the preliminary synthesis and characterization of an electroactive, conducting polymer that should readily bind metal cation. Anodic polymerization of the Schiff base resulting from the condensation reaction between 1,8-diaminonaphthalene and dehydroacetic acid, 8-(3-acetylimino-6-methyl-2.4-dioxopyran)-1-aminonaphthalene, on platinum electrode in acetonitrile was found to yield thin, electroactive polymeric films. Thr films were found electroactive in acetonitrile and aqueous sulfuric acid solution and the electroacity is attributed to the electron transformation of the amino/imine sites in the polymer as in aromatic amine polymers. Electrochemical studies of electron-transfer reactions on the polymer-covered platinum electrodes indicated that the polymer films are highly porous and semiconducting.
