Electroactive, light-emitting film-forming polymer materials used in electrophotography, electroluminescent material and electrochromic display are derived from bis(aryl-hydroxymethyl)-(hetero)arene and N,N'-diaryl-arylene diamine

摘要

Electroactive and light-emitting polymer materials, forming films from solution, contain polymer(s) (I), comprising polycondensates of bis(aryl-hydroxymethyl)-(hetero)aromatic compounds and N,N'-diaryl-arylene diamines. Electroactive and light-emitting polymer materials, forming films from solution, contain polymer(s) of formula (I), comprising polycondensates of bis(aryl-hydroxymethyl)-(hetero)aromatic compounds and N,N'-diaryl-arylene diamines. Y = a divalent aryl-substituted arylene diamine derivative of formula (II); m = 1, 2 or 3; R = alkyl or aryl; R' = alkyl, alkoxy or halogen; Z = divalent (hetero)aromatic groups; Ar, Ar' = aryl; n = 5-5000 The full definitions are given in the DEFINITIONS (Full Definitions) Field. An Independent claim is also included for the preparation of a (I) solution.
