▎ 摘　　要

NOVELTY - Polyarylsulfone/polyarylketone based electrochromic polymer film comprises polyarylsulfone/polyarylketone repeating unit (I) is new. (I) has electrochemical sites. USE - The electrochemical sites containing polyarylsulfone/polyarylketone based electrochromic polymer film useful in electrochromism, electroluminescence, aggregation-induced luminescence, information storage and supercapacitor (claimed). ADVANTAGE - The polyarylsulfone/polyarylketone based electrochromic polymer film comprises: has excellent cycle stability, can be directly polymerized and grown on the electrode surface to form a film; can effectively control the thickness of the film. DETAILED DESCRIPTION - Polyarylsulfone/polyarylketone based electrochromic polymer film (A) comprises polyarylsulfone/polyarylketone repeating unit of formula (I) is new. n = positive integer, indicating the degree of aggregation; X = diphenylaminyl of formula (X1) or 9H-carbazol-9-yl of formula (X2); T = disulfuryl of formula (T1), (disulfinyl)benzene of formula (T2), dicarbonyl of formula (T3) or (dicarbonyl)benzene of formula (T4). An INDEPENDENT CLAIM is also included for preparation of (A).
