METAL COMPLEXES COMPRISING DIAZABENZIMIDAZOL CARBENE-LIGANDS AND THE USE THEREOF IN OLEDS

摘要

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