The present invention relates to polymers which contain at least one carbazole structural unit of the general formula (I) where Ar1, Ar2, Ar3 is each, independently of one another, an aryl or heteroaryl group, which may be substituted by one or more radicals R of any desired type; m, o is, independently of one another, 0 or 1; 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) where Ar4, Ar5, Ar7, Ar8 is each, independently of one another, an aryl or heteroaryl group, which may be substituted by one or more radicals R of any desired type; Ar6 is an aryl or heteroaryl group, which may be substituted by one or more radicals R of any desired type, or represents a group of the formula Ar9-Y—Ar9, where Ar9 is in each case, independently, an aryl or heteroaryl group, which is substituted by one or more radicals R of any desired type or which may be linked to one another, and Y is a spacer group or a direct bond; p is 1, 2 or 3; q is 0 or 1 and the dashed lines represent the linking in the polymer. Furthermore, the present invention relates to processes for the preparation of these polymers and to formulations and electronic devices which comprise these polymers. |
