Substituent effects on electrochemical and electrochromic properties of aromatic polyimides with 4-(carbazol-9-yl)triphenylamine moieties

Three series of aromatic polyimides with 4-(carbazol-9-yl)triphenylamine moieties were prepared from the polycondensation reactions of 4,4′-diamino-4″-(carbazol-9-yl) triphenylamine (1), 4,4′-diamino-4″-(3,6-di-tert-butylcarbazol-9-yl)triphenylamine (t-Bu-1), and 4,4′-diamino-4″-(3,6-dimethoxycarbazol-9-yl) triphenylamine (MeO-1), respectively, with various commercially available tetracarboxylic dianhydrides. In addition to high thermal stability and good film-forming ability, the resulting polyimides exhibited an ambipolar electrochromic behavior. The polyimides based on t-Bu-1 and MeO-1 revealed higher redox-stability and enhanced electrochromic performance than the corresponding ones based on 1 because the active sites of their carbazole units are blocked with bulky t-butyl or electron-donating methoxy groups. 2014 Wiley Periodicals, Inc. J. Polym. Sci., Part A: Polym. Chem. 2014, 52, 1172-1184 Three series of 4-(carbazol-9-yl)triphenylamine-based aromatic polyimides are prepared by polycondensation of corresponding diamines with various commercially available tetracarboxylic dianhydrides. All the polyimides afford flexible and tough films with high thermal stability. The polymer films show ambipolar redox and multicolored electrochromic behaviors. During the electro-oxidation processes, the polyimides with t-butyl or methoxy substituents on the pendent carbazole unit exhibit enhanced electrochemical stability and electrochemical performance, as compared with the coresponding parent polyimides, because the electrochemically active sites of carbazole are blocked.
