Abstract

An organic light-emitting component has an active layer for emitting electromagnetic radiation. It also has an anode and an organic charge transport layer, arranged between the active layer and the anode, for transporting charge carriers from the anode to the active layer. The anode can be used to decouple electromagnetic radiation emitted by the active layer from the organic light-emitting component. The organic charge transport layer comprises a copper complex which has at least one ligand with the chemical structure as per a formula I.
