Abstract

An organic electronic component includes a substrate and a first electrode arranged on the substrate, and at least one organic functional layer arranged on the first electrode. The organic functional layer includes a matrix material into which a p-dopant has been introduced and a second electrode arranged on the organic functional layer. The p-dopant includes a copper complex having at least two ligands. Each ligand has a benzene unit with six carbon atoms. With respect to each ligand, an iminium group is linked directly as a substituent to one of the six carbon atoms of the benzene unit, and an oxygen is bound as a substituent to an adjacent carbon atom of the benzene unit, with the oxygen and the benzene unit together forming an aryloxy group. The ligands are coordinated to the copper cation, so that the copper complex has a trans-structure. The organic functional layer is hole-conducting.
