Oligomeric metallo phthalocyanine-incorporated conducting polymers

Pyrrole and aniline were polymerized electrochemically in aqueous media using sodium salt of metallo phthalocyanine oligomer possessing carboxyl terminals as the supporting electrolyte. The polymers get coated as thin films in platinum cathode, and they were characterised by IR, UV-Vis, ESCA, and electrochemical and electrical conductivity measurements. The voltammetric measurements of the oligomeric metallo phthalocyanine-incorporated polypyrrole indicate stable and reversible electrochemical behaviour in aqueous KCl media. Monomeric metallo phthalocyanine-incorporated polypyrrole was also prepared and the electrochemical properties were studied. Oligomeric nickel phthlocyanine-incorporated polyaniline shows poor electrochemical behaviour in aqueous KCl.
