The redox active anthraquinone diimines-terpyridine base metallosupramolecular polymers (MSPs) were synthesized from amine and 9,10-anthraquinone, respectively. The electrochemistry and electrochromic properties of these polymers were investigated. The spin-coating of polymer films exhibited reversible electrochemical processes and strong color changes upon electro-oxidation or electro-reduction. The remarkable electrochromic behavior of the film was clearly interpreted from spectroelectrochromic study and stability was evaluated by the electrochromic cyclic switching studies.
