Abstract

The invention relates to an organic electronic component (100) comprising at least one charge generation layer (5) which has an organically p-doped region (5a) that contains a zinc complex as a p-dopant, said zinc complex in turn containing at least one ligand L of the following structure: formula (I) wherein R1 and R2 can be oxygen, sulphur, selenium, NH or NR4 independently from one another, wherein R4 is selected from the group containing alkyl or aryl and which can be bonded to R3; and wherein R3 is selected from the group containing alkyl, long-chain alkyl, cycloalkyl, halogen alkyl, at least partially halogenated long-chain alkyl, halogen cycloalkyl, aryl, arylene, halogen aryl, heteroaryl, heteroarylene, heterocyclic alkylene, heterocycloalkyl, halogen heteroaryl, alkenyl, halogen alkenyl, alkynyl, halogen alkynyl, ketoaryl, halogen ketoaryl, ketoheteroaryl, ketoalkyl, halogen ketoalkyl, ketoalkenyl, halogen ketoalkenyl, halogen alkyl aryl, and halogen alkyl heteroaryl, wherein, for suitable groups, one or a number of non-adjacent CH2 groups can be replaced by —O—, —S—, —NH—, —NR∘∘∘—, —SiR∘R∘∘—, —CO—, —COO—, —COR∘OR∘∘—, —OCO—, —OCO—O—, —SO2-, —S—CO—, —CO—S—, —O—CS—, —CS—O—, …
