4-Diphenylamino-phenyl substituted pyrazine: Nonlinear optical switching by protonation

Through the integration of a 4-diphenylamino-phenyl unit with a pyrazine segment, a series of novel organic conjugated molecules with different spacers and shapes have been synthesized and fully characterized. These as-prepared compounds exhibit reversibl

Electropolymerization of V-shape D-A-D type monomers for efficient and tunable electrochromics

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, respectively. 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 behaviours 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 additional substituents on the quinoxaline parts, respectively.
