Pyrrole and aniline were polymerized electrochemically in aqueous media usi
ng sodium salt of metallo phthalocyanine oligomer possessing carboxyl termi
nals as the supporting electrolyte. The polymers get coated as thin films i
n platinum cathode, and they were characterised by IR, UV-Vis, ESCA, and el
ectrochemical and electrical conductivity measurements. The voltammetric me
asurements of the oligomeric metallo phthalocyanine-incorporated polypyrrol
e indicate stable and reversible electrochemical behaviour in aqueous KCl m
edia. Monomeric metallo phthalocyanine-incorporated polypyrrole was also pr
epared and the electrochemical properties were studied. Oligomeric nickel p
hthlocyanine-incorporated polyaniline shows poor electrochemical behaviour
in aqueous KCl. (C) 2000 Elsevier Science S.A. All rights reserved.
