Wang, Wenyuan; Chen, Hongjin; Yue, Youfeng; Zhang, Rui; Liu, Jian published the artcile< Electropolymerization of V-shape D-A-D type monomers for efficient and tunable electrochromics>, Recommanded Product: 4,5-Dimethoxybenzene-1,2-diamine, the main research area is electrochromic triphenylamine quinoxaline derivative preparation electrochem polymerization.
Five novel donor-acceptor-donor (D-A-D) type monomers (VQ1 ∼ VQ5) with a common V-shape configuration have been developed and further electropolymerized for electrochromic applications. The monomers were designed by introducing two triphenylamine groups into the 2- and 3- position of the quinoxaline derivates, resp. These redox-active monomers could be electrodeposited robustly on the ITO electrodes in an electrolyte solution via the oxidative coupling reactions between triphenylamine radical cations. The obtained thin polymer films (PVQ1 ∼ PVQ5) exhibited reversible redox behaviors and obvious color changes upon voltage variation. All these polymers exhibited excellent electrochromic performances involving high optical contrast (over 70%), short response time (less than 2 s) and high coloration efficiency (over 200 cm2 C-1). Moreover, the optical properties of these polymers in both neutral state and oxidation state can be tuned by variation of the addnl. substituents on the quinoxaline parts, resp.
