Abstract:
1. A compound of the formula (1), formula (2), formula (3) or formula (4): wherein the compound of the formula (1) is selected from compounds of the following formulae (11a) to (31b): where the following applies to the symbols and indices used: A is on each occurrence, identically or differently, CR or N; W is C if a group Y is bonded to this group W and is CR or N if no group Y is bonded to this group W; with the proviso that at least one symbol A and/or at least one symbol W stands for N; X is on each occurrence, identically or differently, N, P or P═O; Y is C(R wherein one or two R groups are selected from structures of the following formulae (32) to (67): and the other R groups stand for H or D; Z is on each occurrence, identically or differently, CR Ar m is on each occurrence, identically or differently, 0, 1, 2 or 3, E is selected from the group consisting of C(R G is selected from the group consisting of NR R R R Ar is on each occurrence, identically or differently, an aromatic or heteroaromatic ring system having 5-30 aromatic ring atoms, which is optionally substituted by one or more non-aromatic radicals R L is a di-, tri-, tetra-, penta- or hexavalent straight-chain alkylene, alkylidene, alkyleneoxy or thioalkyleneoxy group having 1 to 40 C atoms or a branched or cyclic alkylene, alkylidene, alkyleneoxy or thioalkyleneoxy group having 3 to 40 C atoms or an alkenylene or alkynylene group having 2 to 40 C atoms, each of which may be substituted by one or more radicals R n is on each occurrence, identically or differently, 0 or 1; and p is 2, 3, 4, 5 or 6, with the proviso that p is not greater than the maximum valence of L.
