ELECTRO-OXIDATIVE OLIGOMERIZATION OF 1,5-DIAMINONAPHTHALENE IN ACETONITRILE MEDIUM

New electroactive oligomer films of 1,5-diaminonaphthalene have been p repared on platinum and carbon graphite electrodes in acetonitrile sol ution by potential sweep electrolysis and controlled potential electro lysis. The films were electroactive in aqueous acidic solutions with a formal redox potential of ca. 0.33 V vs. SCE in 1 M HCl solution. Cyc lic voltammetry, controlled potential electrolysis, SEM, FT-IR spectro scopy, H-1 NMR, conductivity measurements and gel permeation chromatog raphy were used to characterize the oligomeric film.
