Claim 10:
11. An OLED comprising a heteroleptic complex according to claim 1 and at least one compound of the formula (X), in which T is NR57, S, O or PR57;, R57 is aryl, heteroaryl, alkyl, cycloalkyl or heterocycloalkyl;, Q′ is —NR58R59, —P(O)R60R61, PR62R63, S(O)2R64, —S(O)R65, —SR66, —OR67, or, wherein
R68, R69 are each independently alkyl, cycloalkyl, heterocycloalkyl, aryl or heteroaryl;
y, z are each independently 0, 1, 2, 3 or 4;
R55, R56 are each independently alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, SiR70R71R72, a group Q′ or a group with donor or acceptor action;
a″ 0, 1, 2, 3 or 4;
b′ 0, 1, 2 or 3;
R58, R59 together with the nitrogen atom form a cyclic radical which has 3 to 10 ring atoms and may be unsubstituted or substituted by one or more substitutents selected from alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl and a group with donor or acceptor action and/or may be fused to one or more further cyclic radicals having 3 to 10 ring atoms, where the fused radicals may be unsubstituted or substituted by one or more substituents selected from alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl and a group with donor or acceptor action;
R70, R71, R72, R60, R61, R62, R63, R64, R65, R66, R67 are each independently aryl, heteroaryl, alkyl, cycloalkyl or heterocycloalkyl,
or
two units of the general formula (X) are bridged by a linear or branched, saturated or unsaturated bridge, optionally interrupted by at least one heteroatom, by a bonding or by O.
