ORGANIC ELECTRONIC COMPONENT HAVING A CHARGE GENERATION LAYER AND USE OF A ZINC COMPLEX AS A P-DOPANT IN CHARGE GENERATION LAYERS

摘要

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 CH₂sb / 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-, -CY1=CY2 or -C≡C- independently from one another, and in such a way that O and/or S atoms are not directly bonded to one another, and are replaced optionally with aryl- or heteroaryl preferably containing between 1 and 30 C atoms (terminal CH₃ groups are understood to be CH₂ groups in the sense of CH2-H). sb / The invention further relates to the use of a zinc complex as a p-dopant in charge generation layers.
