The electrooxydative polymerization of nickel complex of 1,5-diaminonaphthalene was performed in acetonitrile containing lithium perchlorate, using cyclic voltammetry and controlled potencial electrolysis. The film coated electrode showed an electroactive redox response in acidic solutions only. The stability of the redox response towards repetitive cyclic voltammetry was studied. The formal redox potential of the resulting film electrode was about 0.28 V vs. Ag/Ag(+) in 1.0 M acid chloride aqueous solution (ph=0). The electrical conductivity of the film was measured in 0,01 M KCl aqueous solution and was found as (2.2 (+/-) 0.02) 10(-4) S cm(-1). The morphology of the film and the factors affecting its electroactivity were studied in detail.
