Patent ID: 8580395

Claim:
An organic electronic device having one or more active layers, wherein at least one of these active layers comprises one or more polymers wherein the polymer consists of 0.01 to 50 mol % of one or more structural units of formula (I) or (II), where the symbols and indices used have the following meanings: R 1 to R 10 are, independently of one another, identically or differently, H, halogen (F, Cl, Br, I), —CN, —NO 2 , —NCS, —NCO, —OCN, —SCN, —SF 5 , —Si(R) 3 or a straight-chain, branched or cyclic alkyl or alkoxy group having 1 to 22 C atoms, in which, in addition, one or more non-adjacent C atoms is optionally replaced by —C(R)═C(R)—, —C≡C—, —N(R)—, —O—, —S—, —CO—, —CO—O—, —O—CO— or —O—CO—O—, where, in addition, one or more H atoms is optionally replaced by fluorine, an aryl, aryloxy, heteroaryl or heteroaryl-oxy group having 5 to 40 C atoms, which is optionally substituted by one or more non-aromatic radicals R 1-10 , where, in addition, two or more radicals of the radicals R 1-10 optionally forms with one another an aliphatic or aromatic, mono- or polycyclic ring system, which optionally forms a condensed ring system with the benzene ring or the thiophene ring in the formula (I) and/or (II), R is on each occurrence, identically or differently, H, halogen, a straight-chain, branched or cyclic alkyl chain having 1 to 22 C atoms, in which, in addition, one or more non-adjacent C atoms is optionally replaced by —O—, —S—, —CO—, —CO—O—, —O—CO— or —O—CO—O—, where, in addition, one or more H atoms is optionally replaced by fluorine, an aryl, aryloxy, heteroaryl or heteroaryloxy group having 5 to 40 C atoms, which is optionally substituted by one or more non-aromatic radicals R 1-10 , where, in addition, two or more radicals R may form with one another and/or with further radicals R 1-10 an aromatic or aliphatic, mono- or polycyclic ring system, which optionally forms a condensed ring system with the benzene ring or the thiophene ring in the formula (I) and/or (II), X is S or O, and structural units, which have hole-injection and/or hole-transport properties, and structural elements, which are used as backbone; wherein the structural units, which have hole-injection and/or hole-transport properties are triarylamine and wherein the structural elements, which are used as backbone are 4,5-dihydropyrene, 4,5,9,10-tetrahydropyrene, fluorene, 9,9′-spirobifluorene, phenanthrene, 9,10-dihydrophenanthrene, 5,7-dihydrodibenzoxepine or cis- and trans-indenofluorene.
