Abstract

An organic electronic component and a method for making an organic electronic component with a p-dopant are disclosed. In an embodiment, the component includes a matrix containing a zinc complex as a p-dopant, the zinc complex 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 selected from one another, wherein R3 may comprise alkyl, long-chain alkyl, cycloalkyl, halogen-alkyl, 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 or halogen-alkyl-heteroaryl, and wherein R4 is selected from the group consisting of alkyl and aryl which can be bonded to R3.
