Abstract

Synthesis and electropolymerization of the new bisthienyl‐substituted diketopyrrolopyrrole monomer 1,4‐diketo‐2,5‐di‐hexyl‐3,6‐bis{[2‐(3',4'‐ethylenedi‐oxy)thienyl]phenyl}pyrrolo[3,4‐c]pyrrole (EDOT‐DPP‐EDOT) is reported. EDOT‐DPP‐EDOT exhibits a low oxidation potential of 0.67 V versus ferrocene and can be electropolymerized to form a stable, well adherent polymer thin film at the ITO anode. The polymer film is insoluble in organic solvents, non‐fluorescent, but exhibits reversible electrochromic properties with color changes from deep blue in the neutral state via transparent gray to purple red in the oxidized state. The reversibility in air is excellent.
