Synthesis and Characterization of Electrochromic Photo Switch Based on Aniline Oligomer

Generally, chromic is a compound that by external stimuli could change its color reversibly. Most of the stimuli could be used for this purpose. In this study, we synthesized a conductive oligomer with a good solubility based on pentamer aniline. In this reversibility study, electrochemical replacement of this compound was investigated by photochemical properties. In addition, electrochemical oxidation of this compound was investigated by UV-vis spectroscopy.Accordingly, we synthesized a compound that is multi-stimuli responsive to external excitations such, pH, and electrical current and these stimuli have different impacts on the conductivity of the compound in different circumstances.
