The invention relates to the use in organic light-emitting diodes of transition metal carbene complexes, wherein the bond of the one or more carbene ligands to the transition metal is exclusively effected via carbene carbon atoms. The invention also relates to organic light-emitting diodes which contain at least one of the aforementioned transition metal carbene complexes, to a light-emitting layer which contains at least one of the aforementioned transition metal carbene complexes, to organic light-emitting diodes which contain at least one light-emitting layer according to the invention, and to devices which contain at least one organic light-emitting diode according to the invention. |
