Ferrocene‐substituted conducting polymer namely poly( trans ‐1‐(4‐methyl‐3′‐thienyl)‐2‐(ferrocenyl)ethene‐ co ‐3,4‐ethylenedioxythiophene) [P(MTFE‐ co ‐EDOT)] was synthesized and its electrochromic properties were studied. Monomer, MTFE, was obtained using 2‐(ferrocenyl)ethene and 3‐methyl‐4‐bromothiophene. The structure of monomer was determined via Fourier transform infrared spectroscopy (FTIR), 1 H‐NMR, and 13 C‐NMR techniques. The copolymer was synthesized using this monomer and EDOT. The resulting copolymer P(MTFE‐ co ‐EDOT) was characterized by cyclic voltammetry, FTIR, scanning electron microscopy, atomic force microscopy, and UV–vis spectroscopy. The conductivity measurements of copolymer and PEDOT were accomplished by the four‐probe technique. Although poly( trans ‐1‐(4‐methyl‐3′‐thienyl)‐2‐(ferrocenyl)ethene) [P(MTFE)] reveals no electrochromic activity, its copolymer with EDOT has two different colors (violet and gray). Band gap ( E g ) and λ max of P(MTFE‐ co ‐EDOT) were determined. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
