Abstract:
1. A polymer containing at least one carbazole structural unit of the general formula (Ia) where Ar m and o are independently of one another, 0 or 1; n is 1, 2 or 3 and the dashed lines represent a covalent single bond linking to the polymer; and at least one arylamine structural unit of the general formula (IIa) and/or (IIIa) where Ar R is selected on each occurrence, independently of one another, from F, Cl, Br, I, N(Ar) Y is a linear or branched alkylene group having 1 to 20 C atoms, in which one or more non-adjacent CH q is 0 or 1 and the dashed lines represent a covalent single bond linking to the polymer.
