The synthesis and electropolymerization of 2-[2-(l-pyrrolyl)ethylamino]-3-chloronaphthoquinone (PNQ) and 2,5-bis[2-(1-pyrrolyl)ethylamino]-2,6-dichlorobenzoquinone (PBQ). are described. Electrochemical behaviour of poly(PNQ) and poly(PBQ) films on platinum electrodes was investigated in acetonitrile media. A stable composite film was obtained by the oxidation of PNQ on a polypyrrole coated Pt electrode.
