| abstract |
The present invention relates to polymers containing at least one carbazole structural unit of formula (I) and at least one arylamine structural unit of formula (II) and / or (III) [Wherein, Ar 1 , Ar 2 , Ar 3 are each independently of each other an aryl or heteroaryl group which may be substituted by any desired type of one or more radicals R; m and o are independently of each other 0 or 1; n is 1, 2 or 3; The dotted line indicates the connection in the polymer; [Wherein, Ar 4 , Ar 5 , Ar 7 , Ar 8 Are each independently of each other an aryl or heteroaryl group which may be substituted by any desired type of one or more radicals R; Ar 6 is an aryl or heteroaryl group that may be substituted by any desired type of one or more radicals R, or is a group of the formula Ar 9 -Ar 9, wherein Ar 9 in each case, independently, An aryl or heteroaryl group which may be substituted or linked together by R; p is 1, 2 or 3; q is 0 or 1; The dotted line indicates the connection in the polymer. |
