Abstract

The present invention relates to metal-carbene complexes comprising a central atom selected from iridium and platinum, and diazabenzimidazolocarbene ligands, to organic light diodes which comprise such complexes, to light-emitting layers comprising at least one such metal-carbene complex, to a device selected from the group comprising illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED and to the use of such a metal-carbene complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge or exciton blocker.
