Claim 11:
12. The OLED according to claim 11 comprising at least one compound of formula (XI) or (XI*), wherein
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 or —OR67;
R70, R71, R72 are each independently aryl, heteroaryl, alkyl, cycloalkyl, heterocycloalkyl, wherein of at least one of the radicals R70, R71, R72 comprises at least two carbon atoms or OR73,
R55, R56 are each independently alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, a group Q or a group with donor or acceptor action;
a′, b′ are for the compound of formula (XI): each independently 0, 1, 2, 3; for the compound of formula (XI*) a′ is 0, 1, 2 and b is′ 0, 1, 2, 3, 4;
R58, R59 together with the nitrogen atom form a cyclic radical which has 2 to 10 ring atoms and 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 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;
R73 is independently SiR74R75R76, aryl, heteroaryl, alkyl, cycloalkyl or heterocycloalkyl, optionally substituted with a group OR77 
R77 is independently SiR74R75R76, aryl, heteroaryl, alkyl, cycloalkyl or heterocycloalkyl,
R60, R61, R62, R63, R64, R65, R66, R67, R74, R75, R76 are each independently aryl, heteroaryl, alkyl, cycloalkyl or heterocycloalkyl,
or
two units of the general formulae (XI) and/or (XI*) are bridged by a linear or branched, saturated or unsaturated bridge, optionally interrupted by at least one heteroatom or by O, wherein said bridge is bonded in the general formulae (XI) and/or (XI*) each time instead of R71 to the Si-atoms.
