Abstract
We synthesized triphenylamine-based zwitterion TPA-SB, maleimide-functionalized triphenylamine TPA-MI, and triphenylamine derivatives compound 9, 10, 11. A systematic analysis for electrochemical polymerization of triphenylamine on an indium – tin oxide (ITO) electrode was performed, and the polymer film was investigate by scanning electron spectroscopy (SEM). There are two studies：(1)Bioelectronic character：Electrochemical polymerization of TPA-SB with different fractions of TPA-MI develop a bionic conducting polymer on ITO. Using X-ray photoelectron spectroscopy (XPS) calculate the compositions of the copolymer films. The resistance of polymer films towards the adhesion of proteins resulted from the highly hydrophilic yet net-neutral properties of the zwitterion on surfaces, so we test the surfactant hydrophilicity by water droplet contact angles analysis. (2)Electrochromic character：The triphenylamine polymer film have electrochromic character. Using spectroelectrochemistry (SEC) to discuss the correlation between electrochemical reaction and color change of polymer film.
