Abstract

The present invention relates to metal-carbene complexes comprising a central atom selected from iridium and platinum, and specific azabenzimidazolocarbene ligands, to OLEDs (Organic Light Emitting Diode, OLED) which comprise such complexes, to a device selected from the group consisting of illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED, 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.
