Organic electronic device and method for the production thereof

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/m), 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.

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

An organic semiconductor component with a hole conductor layer having p-type doping with a superacid salt has greatly improved charged transport and optical properties. Besides increasing the specific conductivity at very low doping concentrations, the doping brings about substantially no negative change in the color impression of the layer for the human eye. The absorbtivity of the hole conductor layer is not increased in the visible wavelength range as a result of the p-type doping with the superacid salt. Deposition from solution and from the gas phase is possible.

The first functional organic layer includes a matrix material and a p-dopant with regard to the matrix material, wherein the p-dopant includes a copper complex containing at least one ligand.
