We herein report the electrosynthesis of an aminomethyl functionalized poly(3,4-ethylenedioxythiophene)(PEDOT) derivative, poly(2’-aminomethyl-3,4-ethylenedioxythiophene)(PEDOT-Me NH2), in CH2Cl2-Bu4NPF6(0.1 mol·L-1) system containing 2% boron trifluoride diethyl etherate(BFEE). The electrochemical behavior, structure characterization, thermal properties and surface morphology of this novel polymer were systematically investigated by cyclic voltammetry(CV), Fourier-transform infrared spectroscopy(FTIR), thermogravimetry(TG) and scanning electron microscopy(SEM), respectively. Electrochemistry results demonstrated that PEDOT-Me NH2 film displayed good redox properties and high electrochemical stability. Besides, PEDOT-Me NH2 films exhibited the electrochromic nature with obvious color changing from purple in the reduced form to blue upon oxidation. By further investigation, kinetic studies revealed that PEDOT-Me NH2 film had decent contrast ratio(41.8%), favorable coloration efficiency(152.1 cm2·C-1), low switching voltages and moderate response time(2.4 s). Satisfactory results implied that the obtained PEDOT-Me NH2 film is a promising optoelectronic material and holds promise for electrochromic devices and display applications.
