Dopant for a hole conductor layer for organic semiconductor components, and use thereof

摘要

The invention relates to novel metal-organic materials for hole injection layers in organic electronic components. For example, in light-emitting components such as organic light diodes (OLED) or organic light-emitting electrochemical cells (OLEEC) or organic field effect transistors or organic solar cells or organic photo detectors. Luminescence (cd/m2), efficiency (cd/A), and service life (h) of organic electronic components such as from organic light diodes in particular are highly dependent on the exciton thickness in the light-emitting layer and on the quality of the charge carrier injection and are also limited by same, among other things. The invention relates to a hole injection layer consisting of quadratic planar mononuclear transition metal complexes such as copper 2+ complexes, for example, which are embedded into a hole-conducting matrix.

1. A hole conductor layer for organic electronic components, in which a dopant comprising a mononuclear square-planar transition metal complex comprising a central atom and ligands has been introduced into a hole conductor matrix, wherein the transition metal complex has the following general formula: wherein Y1 or Y2 each independent are selected from N or C—R, X1 and X2 each independently are selected from O or N—R, R, R1a, R1b, R2a and R2b each independently are selected from the group of the following substituents:
hydrogen, deuteriumunbranched, branched, fused, cyclic or fully or partly substituted alkyl substituents (C1-C20), wherein said alkyl substituents may contain ether groups, ester groups, amide groups, carbonate groups and halogens,substituted or unsubstituted aromatics and heterocycles.
