Abstract
The conjugated copolymers 3, 4-ethylenedioxythiophene (EDOT) and 3, 4-ethylenedithiothiophene (EDTT) units have been investigated by cyclic voltammetry, electronic absorption spectroscopy and spectroelectrochemistry. The electrochemical properties of the monomer have given higher oxidation potential compared to their polymer. The optical and the electrochemical band gap of the PEDOT have shown a big difference compared to the PEDTT state. These polymers can be use as an electrochromic material.
