In this work, we meticulously designed a Tröger’s base (TB)-cored arylamine-containing diamine monomer, TBTPA-NH2, and synthesized the corresponding redox-active polyamide, PTBTPA. The resulting PTBTPA exhibits low density with large d-spacing and surface area, contributing to the rigid and V-shaped TB unit. Consequently, the prepared polymer film demonstrated remarkable electrochemical and EC behaviors, such as low applied potential (1.00 V), facilitating rapid diffusion of the electrolyte, reasonable switching capability (1.8 s/1.5 s for coloring tc and bleaching tb, respectively), and excellent stability. For further application, the electrochromic device (ECD) of PTBTPA/HV exhibits the best-enhanced response capability (3.5 s/6.1 s for tc and tb, respectively), the highest coloration efficiency (337 cm2/C), and switching stability (96.1% of retention after 500-cycle switching). |
