Its oxidative electropolymerization film with a non-diffusion controlled redox behaviour and an inverse dependence of AC impedance on its thickness has also been obtained by cyclic voltammetry on the working ITO electrode. The hybrid film possesses interesting dual-wavelength electrochromic properties in visible and near-infrared spectral regions.
