Abstract

The present invention relates to the use of transition metal-carbene complexes in organic light-emitting diodes (OLEDs), to a light-emitting layer, to a blocking layer for electrons or excitons, or to a blocking layer for holes, each comprising these transition metal-carbene complexes, to OLEDs comprising these transition metal-carbene complexes, to devices which comprise an inventive OLED, and to transition metal-carbene complexes.
