dc.description.abstract | Generally, the amino group is considered highly reactive and unstable. Thus, the amino derivatives would be entirely consumed by polymerization or end-capping to preserve the material stability in most research or application fields. Herein, we demonstrated that triphenylamine (TPA) with multiple para-amino substituents could reduce oxidation potential and provide extra oxidation sites while retaining their reversibility. Four para-amino-substituted TPA derivatives (TPA-1N, TPA-2N, TPA-3N, and TPA-ADM) designed and prepared in this study exhibited excellent stability under the electrochemical redox procedure, revealing more than 88% reversibility in the continuous cyclic voltammetry process up to 10,000 cycles. Among all the electrochromic devices, TPA-3N/HV performs the highest coloration efficiency (631 cm2/C), coloration speed (46.4 % s−1), and superior stability, manifesting a reversibility of 99% or 98% after 1000 cycles (switching) or 10 h (maintaining at coloring state), respectively. | en_US |
