Several vinylcarbazole derivatives were electrochemically polymerized into electrochromic films with electrical conductivities in the range of 10(-4) to 10(-7) S/cm. The characteristic white/green color change upon doping was due to bicarbazolyl groups. The cyclic voltammograms of the monomers revealed small differences due to the various positions of the vinyl group on the ring.
