Claim:
A compound of the general formula (I), where the symbols and indices have the following meanings: Q′, Q″, Q′″, and Q″″ are identical or different on each occurrence and are each CN, F, Cl or a straight-chain or branched or cyclic alkyl or alkoxy group which has from 1 to 20 carbon atoms and in which one or more nonadjacent CH 2 groups is optionally replaced by —O—, —S—, —CO—, —COO—, —O—CO—, —NR—, —(NR 2 R 3 ) + -A − or —CONR 4 — and one or more H atoms is optionally replaced by F, or an aryl or heteroaryl group which has from 4 to 14 carbon atoms and is optionally substituted by one or CN, F, Cl or a straight-chain or branched or cyclic alkyl or alkoxy group which has from 1 to 20 carbon atoms and in which one or more nonadjacent CH 2 groups is optionally replaced by —O—, —S—, —CO—, —COO—, —O—CO—, —NR 1 —, ˜(NR 2 R 3 ) + -A − or —CONR 4 — and one or more H atoms is optionally replaced by F; A − is a singly charged anion or its equivalent; R 1 , R 2 , R 3 , and R 4 are identical or different and are each H or an aliphatic or aromatic hydrocarbon radical having from 1 to 20 carbon atoms; n are identical or different and are each 0, 1, 2, 3; X is —CH— or N; Y1 to Y6: include at least two identical or different substituents of the formula (II) and the remaining Y1 to Y6 in the positions of the aromatic which are not occupied by formula (II) are identical or different substituents Q′ or H, where the formula (II) is where Aryl 1 and Aryl 2 are identical or different on each occurrence and are each phenyl, 1-naphthyl, 2-naphthyl, 1-anthracenyl, 2-anthracenyl, 9-anthracenyl, 2-pyridinyl, 3-pyridinyl, 4-pyridinyl, 2-pyrimidinyl, 4-pyrimidinyl, 5-pyrimidinyl, 2-pyrazinyl, 3-pyridazinyl, 4-pyridazinyl, 2-quinolinyl, 3-quinolinyl, 4-quinolinyl, 5-quinolinyl, 6-quinolinyl, 7-quinolinyl, 8-quinolinyl, 2-thienyl, 3-thienyl, 2-pyrrolyl, 3-pyrrolyl, 2-furanyl, 3-furanyl or 2-(1,3,4-oxadiazol)yl; R′ and R″ are identical or different on each occurrence and are each CN, F, Cl or a straight-chain or branched or cyclic alkyl or alkoxy group which has from 1 to 20 carbon atoms and in which one or more nonadjacent CH 2 groups is optionally replaced by —O—, —S—, —CO—, —COO—, —O—CO—, —NR 1 —, —(NR 2 R 3 ) + A − or —CONR 4 — and one or more H atoms is optionally replaced by F, or an aryl or heteroaryl group which has from 4 to 14 carbon atoms and which is optionally substituted by one or more CN, F, Cl or a straight-chain or branched or cyclic alkyl or alkoxy group which has from 1 to 20 carbon atoms and in which one or more nonadjacent CH 2 groups is optionally replaced by —O—, —S—, —CO—, —COO—, —O—CO—, —NR 1 —, —(NR 2 R 3 ) + A − or —CONR 4 — and one or more H atoms is optionally replaced by F; A − is a singly charged anion or its equivalent; R 1 , R 2 , R 3 , and R 4 are identical or different and are each H or an aliphatic or aromatic hydrocarbon radical having from 1 to 20 carbon atoms; m are identical or different and are each 0, 1, 2, 3, 4, or 5; Z is boron or aluminum.
