Abstract

The present invention relates to dinuclear Pt-carbene complexes comprising carbene ligands and pyrazole bridges, to a process for preparing the dinuclear Pt-carbene complexes by contacting suitable Pt compounds with the corresponding ligands or ligand precursors and/or pyrazole or corresponding pyrazole derivatives, to organic electronic components comprising at least one such dinuclear Pt-carbene complex, to an OLED comprising at least one such dinuclear Pt-carbene complex, to a light-emitting layer comprising at least one such dinuclear Pt-carbene complex, to an OLED comprising such a light-emitting layer, to a device selected from the group consisting of stationary visual display units, mobile visual display units and illumination means, comprising such an OLED, and to the use of an inventive dinuclear Pt-carbene complex in OLEDs.
