Abstract
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.
