Patent ID: 7858724

Claim:
A phosphorescent copolyaryl borane of type K, wherein: x, y and z are molar parts and add up to 1 and the molar parts y and z each are >0, hydrogen atoms are bonded at the ends, M, HT and TE each represent a type of arylene component, M is a matrix structure comprising an arylene structure, the arylene structure being any bivalently linking single- or multi-nucleic aromatic and/or heteroaromatic structure, HT is a substituted 2-amino-thiophene or 2-amino-thiazole structure with hole-transport capability, TE is a bivalent, phosphorescent organo-metallic complex of the following structure: wherein Me denotes a metal of group 8, 9 or 10, Ar 5 is an arylene ligand that can form a complex with the metal Me and simultaneously is capable of polymeric linking, TE does not have the ligand (L-X) if the metal Me is platinum, and for all other Me L-X is a complex-forming ligand, and Ar is a carbocyclic or heterocyclic aryl moiety of which 0, 1 or more of the hydrogen atoms are each substituted by branched or linear aryl moieties or alkoxy moieties (C 1 to C 10 ), phenyl moieties or diphenyl or naphthylphenyl-amino groups.
