Purpald containing poly(2,5-dithienylpyrrole)-based multifunctional conducting polymer: synthesis, characterization, and electrochromic properties


Synthesis of novel purpald (4-amino-5-hydrazino-1,2,4-triazole-3-thiol) containing 2,5-di(2-thienyl)pyrrole (TPTP) derivative monomer has been successfully achieved. Its functional conductive polymer (pTPTP) obtained electrochemically has been characterized and electrooptical properties have been investigated. In this way, multifunctional conductive polymer film has been formed by means of advanced functionalization of thiol and amine group on the polymeric backbone that can be applied in many fields such as metal sensor, biosensor sensor, and biochemical imaging. The potential usage of this multifunctional conductive polymer film in smart windows application has been investigated and the optical contrast value which is the most important parameter of this technology has been measured as 75%.
