- Obtained three novel monomers based on carbazole derivatives and redox groups.
- All the resulting polymer films could show multi-electrochromic property.
- The bleaching time of P(BCB-Fc) and P(BCB-TEMPO) films are found to be 0.79 and 0.73Â s, respectively.
Three novel monomers based on carbazole-3, 4-ethoxylenedioxythiophene and redox groups were synthesized and characterized. Their polymer films were obtained by electropolymerization. Cyclic voltammetry and spectroelectrochemistry of the polymer films showed that they possessed multi-electrochromic property. The presence of ferrocene and 2,2,6,6-tetramethyl-1-piperidinyloxy units not only changed the films' colour but also improved their switching time due to their excellent electrochemical properties. Additionally, the polymer films also possessed a reasonable transmittance change, which made them promising candidates for use in electrochromic devices.
