abstract |
The invention relates to polymers containing at least one carbazole structural unit of the general formula (I), in which Ar1, Ar2, Ar3 are each an aryl or heteroaryl group independently of one another, said group being substitutable with any one or more groups R; m, o are 0 or 1 independently of each other; n is 1, 2, or 3, and the dashed lines represent the linking in the polymer; and at least one arylamine structural unit of the general formula (II) and/or (III), in which Ar4, Ar5, Ar7, Ar8 are each an aryl or heteroaryl group independently of one another, said group being substitutable with any one or more groups R; Ar6 is an aryl or heteroaryl group, which can be substituted with any one or more groups R or is a group of the formula Ar9-Ar9, in which each Ar9 is independently an aryl or heteroaryl group, each group being substitutable with any one or more groups R or said groups being linkable with each other; p is 1, 2, or 3; q is 0 or 1, and the dashed lines represent the linking in the polymer. The invention further relates to methods for producing said polymers and to formulations and electronic devices that contain said polymers. |
