ORGANISCHE LICHTEMITTIERENDE EINRICHTUNGEN MIT TRÄGERBLOCKIERSCHICHTEN MIT METALLKOMPLEXEN

摘要

Light emitting devices having blocking layers comprising one or more metal complexes are provided. The blocking layers may serve to block electron, holes, and/or excitons. Preferably, the devices further comprise a separate emissive layer in which charge and/or excitons are confined. Metal complexes suitable for blocking layers can be selected by comparison of HOMO and LUMO energy levels of materials comprising adjacent layers in devices of the present invention.
