摘要: Abstract A copolymer based on selenophene and 3,4-ethylenedioxythiophene was successfully synthesized by electrochemical polymerization in boron trifluoride diethyl etherate (BFEE). The resultant characterized cyclic voltammetry, FTIR, XPS, SEM spectroelectrochemistry. presented tricolor electrochromism, which dark green-yellow (in the neutral state), blue-green intermediate state) blue oxidized state). Furthermore, optical contrast switching time of found to be 19.8% 3.2 s at 728 nm, respectively, remained 75.1% its original electroactivity after 200 cycles.
