[摘要]：A series of organosoluble polyamides based on N-phenothiazinylphenyl redox units showing anodically electrochromic characteristics both in the near-infrared (NIR) and visible light regions were prepared from the phosphorylation polyamidation reactions of a newly synthesized diamine monomer, 4,4'-diamino-4 ''-N-phenothiazinyltriphenylamine, with various dicarboxylic acids. These polymers were readily soluble in many polar solvents and showed useful levels of thermal stability associated with relatively high glass-transition temperatures (T-g) (255-277 degrees C) and high char yields (higher than 67% at 800 degrees C in nitrogen). In addition, the polymer films showed reversible electrochemical oxidation with enhanced NIR contrast, high coloration efficiency (CE), low switching time, and anodic green/purple electrochromic behaviors. |
