In this study, the conducting forms of poly( N ‐vinyl carbazole) (PNVC) doped with HSO 4 − and NO 3 − anions were synthesized electrochemically in dioxane and ethanol. It was observed that the acid concentration was an important factor in the synthesis of the conducting PNVC in dioxane–H 2 SO 4 media. No conducting PNVC film was formed on the electrode surface in the electrolyses carried out with acid concentrations below 2.0 M H 2 SO 4 in dioxane. However, a conducting PNVC film was obtained at lower acid concentrations (i.e., 0.5 M H 2 SO 4 ) when the solvent was switched from dioxane to ethanol. The use of HCl and acetic acid at different concentrations in ethanol or dioxane media failed to yield conducting PNVC. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 74: 1792–1796, 1999
