摘要

A series of novel polymers (coded as BCT-1 to BCT-6 (BTC is block triphenylamine)) based on N-1-(4-aminophenyl)-N-1-phenyl benzene-1,4-diamine, pyridine-2,6-dicarboxylic acid, 4,4'-(phenyl azanediyl)dibenzoic acid (PDA), and different diamine compounds were synthesized successfully through a polymer condensation reaction. For comparison, model polymers, BCT-2,6-pyridine dicarboxylic acid (PA) and BCT-PDA, were synthesized as well. The electrochromic properties of the BCTs were determined via an electrochemical workstation and a UV-visible spectrophotometer. Through electrooxidation, the polymer films showed reversible redox processes and steady color changes. In a comparision of the electrochromic characteristics of the BCTs, almost all the novel polymer films showed a better electrochromism stability, a higher electrochromic coloration efficiency (CE), and a more rapid switching time than BCT-PA and BCT-PDA. Among these polymers, BCT-1 exhibited the highest CE of 266.7 cm(2)/C, and BCT-4 showed the most rapid switching time (color switching time = 3.08 s and bleaching time = 2.01 s).
