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. |

1. A polymer containing at least one carbazole structural unit of the general formula (Ia)where
Ar1, Ar2 and Ar3 is each, independently of one another, an aryl or heteroaryl group, which is optionally substituted by one or more radicals R; 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
Ar4, Ar5, Ar7 and Ar8 is each, independently of one another, an aryl or heteroaryl group, which is optionally substituted by one or more radicals R; R is selected on each occurrence, independently of one another, from F, Cl, Br, I, N(Ar)2, N(R′)2, CN, NO2, Si(R′)3, B(OR′)2, C(═O)Ar, C(═O)R′, P(═O)(Ar)2, P(═O)(R′)2, S(═O)Ar, S(═O)R′, S(═O)2Ar, S(═O)2R′, —CR′═CR′Ar, OSO2R′, a straight-chain alkyl, alkoxy or thioalkoxy group having 1 to 40 C atoms or a branched or cyclic alkyl, alkoxy or thioalkoxy group having 3 to 40 C atoms, each of which is optionally substituted by one or more radicals R′, where one or more non-adjacent CH2 groups is optionally replaced by R′C═CR′, C≡C, Si(R′)2, Ge(R′)2, Sn(R′)2, C═O, C═S, C═Se, C═NR′, P(═O)(R′), SO, SO2, NR′, O, S or CONR′ and where one or more H atoms is optionally replaced by F, Cl, Br, I, CN or NO2, a crosslinkable group or an aromatic or heteroaromatic ring system having 5 to 60 ring atoms, which may in each case be substituted by one or more radicals R′, or an aryloxy or heteroaryloxy group having 5 to 60 ring atoms, which is optionally substituted by one or more radicals R′, or a combination of these systems, where two or more substituents R may also form a mono- or polycyclic, aliphatic or aromatic ring system with one another, where R′ is in each case, independently of one another, H or an aliphatic or aromatic hydrocarbon radical having 1 to 20 C atoms and Ar is an aryl or heteroaryl group having 2 to 30 C atoms; Y is a linear or branched alkylene group having 1 to 20 C atoms, in which one or more non-adjacent CH2 groups may be replaced by —O—, —S—, —NH—, —N(CH3)—, —N—CO—, —N—CO—O—, —N—CO—N—, —CO—, —O—CO—, —S—CO—, —O—COO—, —CO—S, —CO—O—, —CH(halogen)-, —CH(CN)—, —CH═CH— or —C≡C—, or a cyclic alkyl group; q is 0 or 1 and the dashed lines represent a covalent single bond linking to the polymer. |
