摘要

Abstract

We herein report the electrosynthesis of an aminomethyl functionalized poly(3

4-ethylenedioxythiophene) (PEDOT) derivative

poly(2′-aminomethyl-3

4-ethylenedioxythiophene) (PEDOT-MeNH

)

in CH

-Bu

NPF

(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-MeNH

film displayed good redox properties and high electrochemical stability. Besides

PEDOT-MeNH2 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-MeNH

film had decent contrast ratio (41.8%)

favorable coloration efficiency (152.1 cm

·C

-1

)

low switching voltages and moderate response time (2.4 s). Satisfactory results implied that the obtained PEDOT-MeNH

film is a promising optoelectronic material and holds promise for electrochromic devices and display applications.
