Publisher: | Electrochemical Society, Inc. | Abstract: | A new organic-inorganic hybrid monomer, O-2-(9H-carbazyl) ferrocenyldithiophosphonate (CzFc), was synthesized and characterized. Electropolymerization was realized with an applied potential of 1.5 V in boron trifluoride diethyl etherate (BFEE). Spectroelectrochemical and colorimetry studies have shown that P(CzFc) has transmissive colored in neutral state. For switchable glass applications, it has to be two electrochromic polymers have tranmissive states in different oxidation states. So we were constructed dual-type complementary colored polymer switchable glass derived from P(CzFc) as anodically coloring material and P(EDOT) as cathodically coloring material in sandwich configuration. Optoelectrochemical studies indicate that the reduced state of the switchable glass shows blue color for the oxidized state whereas it shows transmissive color for the reduced state. P(CzFc)/P(EDOT) device has good switching time, high optical contrasts and excellent redox stability.
