Diarylethenes have attracted much interest as a switching material and constitute an important class of photochromic molecules. Diarylethenes undergo a reversible ring-closure/opening reaction upon irradiation with UV and visible light, respectively. Stimulating them by irradiation with light at an appropriate wavelength or electrochemically, it is possible to switch their properties not only in electronic absorption but also for various physical and chemical properties, which are important for electronic and photonic applications. A diarylethene substituted with 3,4-propylene-dioxythiophene (ProDOT) was synthesized as a photochromic material. Upon electrochemical oxidation of ProDOT substituted 1,2-bis ( 2-methylbenzo [b] thiophene 3 - yl) perfluorocyclopentene (BTF) , polymeric film was deposited on a PEDOT coated working electrode. This film showed electrochromic property from red to colorless in the potential -2.0V to 2.0V in Ag/AgCl . |
