Synthesis and characterization of novel high-performance polyarylsulfones with 4-(carbazol-9-yl) triphenylamine moieties

A novel homopolyarylsulfone with 4-(carbazol-9-yl) triphenylamine moieties was synthesized successfully through N-C coupling reactions under similar conditions to the synthesis of polyarylsulfones (PSU). By using this simple method and adjusting the feed ratio between 9-(4-aminobenzene) carbazole (NH2-Ar-Cz) and bisphenol A, a series of high-performance copolymers with high molecular weight, good film-reforming ability, great thermal stability, and excellent photoelectric characteristics were also prepared, which have good application potential in the field of organic optoelectronics.
