Electroinitiated polymerization of carbazole was achieved in acetonitrile by direct electron transfer via constant potential electrolysis based on anodic peak potentials. The anodic peak potential of carbazole was determined by cyclic voltammetry to be + 1.4V. It has been observed that polymer yield increased with some factors, such as time, monomer concentration, and polymerization potential. Conducting polycarbazole material obtained on a platinum anode electrode was characterized by FT-IR, TGA, and conductance measurements. The conductivities of samples were measured to be about 10(-3)-10(-4) S/cm by the four-probe method. Temperature-dependence of electrical resistance values of polycarbazole between 30 degrees-125 degrees C suggest that it 0 can be used as a thermal sensor. (c) 2005 Wiley Periodicals, Inc.
