“…TPA was easily oxidized to form a radical cation with a noticeable change of color . Furthermore, because of the incorporation of bulky and three‐dimensional TPA units along the polymer backbone, all the polymers were amorphous with good solubility in many aprotic solvents and exhibited excellent thin‐film‐forming capabilities . The best way to improve the properties is to use more diamino compounds or mix several diamino compounds.…”

A series of novel polymers (coded as BCT-1 to BCT-6 (BTC is block triphenylamine)) based on N 1 -(4-aminophenyl)-N 1phenyl benzene-1,4-diamine, pyridine-2,6-dicarboxylic acid, 4,4 0 -(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).
