Poly(3,4-ethylenedioxythiophene) (PEDOT) is a highly conductive, low band gap (1.6 eV) polymer. In the oxidized state, thin films of PEDOT are stable and nearly transparent. We present here a derivative of EDOT, a new compound, 1-methyl-1_(6-(2,3-dihydrothieno[ 3,4-b][1,4]-dioxine-2-yl-methoxy)-hexyl)-4,4_-bipyridylium bis(hexafluorophosphorane). During electro-polymerization it forms a polymer combining good electrochemical and electrical properties of PEDOT with redox and electrochromic properties of viologen. The monomer was also copolymerized with EDOT. The stability of these polymers was examined using cyclic voltammetry (CV). The CV curves of the thin films of PEDOTM-C6-V2+2PF6 and the copolymer obtained in the solution of the pure electrolyte have proved the existence of the characteristic, reversible redox system at -0.50 V that is assigned to the viologen radical cation.
