An organic light-emitting component (100) has an active layer (110) for emitting electromagnetic radiation (114). It also has an anode (102) and an organic charge transport layer (108), arranged between the active layer (110) and the anode (102), for transporting charge carriers from the anode (102) to the active layer (110). The anode (102) can be used to decouple electromagnetic radiation (114) emitted by the active layer (110) from the organic light-emitting component (110). The organic charge transport layer (108) comprises a copper complex which has at least one ligand with the chemical structure as per formula I: E1 and E2 are each one of the following elements independently of one another: oxygen, sulphur or selenium. R is chosen from the group comprising: hydrogen or substituted or unsubstituted, branched, linear or cyclic hydrocarbons.
