Freestanding and conducting poly[poly(N-vinyl-carbazole)](PPVK) films,with a conductivity of 0.012 S/cm and electrochromic properties,were synthesized electrochemically by direct anodic oxidation of poly (N-vinyl-carbazole)(PVK).The PPVK films thus obtained showed good redox activity and high electrochemical stability in boron trifluoride diethyl etherate.FT-IR data showed that the secondary polymerization of PVK occurred at the benzene ring.The fluorescence spectra suggested that the PPVK in solid state was a good blue light emitter.On the basis of electrochemical impedance spectroscopy data,the anodic oxidation process of PPVK (0.5~1.9 V) can be divided into three segments:p-doping (0.5~1.3 V),transitional region (1.4~1.5 V),and over-oxidative region (1.6~1.9 V).
