Abstract
The present invention relates to the use of transition metal-carbene complexes, in which the carbene ligand(s) is bonded to the transition metal exclusively via carbene carbon atoms, in organic light-emitting diodes, to organic light-emitting diodes comprising at least one aforementioned transition metal-carbene complex, to a light-emitting layer comprising at least one aforementioned transition metal-carbene complex, to organic light-emitting diodes comprising at least one inventive light-emitting layer, and to devices which comprise at least one inventive organic light-emitting diode.
