Abstract:

 

The electrochemical and optical properties of a novel  conducting copolymer called poly(2,5'-dimethyl-[4-(2,5-di-thiophen-  2-yl-pyrrol-1-yl)-phenyl]azobenzene-co-(3,4-ethylenedioxythiophene))  (poly(1-co-EDOT)) are reported.  Electrochemically synthesized  poly(1-co-EDOT) based on the azo dye has a well-defined and reversible  redox couple (0.37 V vs.  Ag/AgCl) with good cycle stability.  The  copolymer film exhibits high conductivity (13 S/cm) as well as  electrochromic behavior (magenta when neutralized and transmissive sky  blue when oxidized).  Furthermore, electro-optically active copolymer  film has a low band gap of 1.79 eV with a p-p* transition at 555 nm.
