Herein, we report the synthesis of a novel, click functionalized 2,5-dithienylpyrrole (SNS-Fc) for the first time. Ferrocene was employed as an anchored unit because of its well-known physical and redox properties. SNS-Fc was electrochemically polymerized and electrochromic properties of the resulting polymer were investigated in detail. In addition, electrochemical copolymerization of SNS-Fc in the presence of 3,4-ethylenedioxythiophene was performed. The resulting copolymer displayed multichromic behavior ranging between orange, yellow, green and blue in different redox states. Cyclic voltammetry studies of both polymers revealed two reversible waves related to the polymer backbone and FeII/III redox couples, while showing the typical characteristic of surface-confined structures. Our studies have shown that the redox behavior, band gap and color of poly(2,5-dithienylpyrrole) derivatives are highly dependent on anchored unit (ferrocene) and copolymerization.
