TRANSITION METAL COMPLEXES WITH TRIPODAL LIGANDS AND THE USE THEREOF IN OLEDS

摘要

The present invention relates to metal complexes of the general formula L 1 ML 2 (I), wherein M is selected from Ir and Rh, L 1 is a ligand of formula L 2 is a ligand of formula to OLEDs (Organic Light-Emitting Diodes) which comprise such complexes, to a device selected from the group consisting of illuminating elements, stationary visual display units and mobile visual display units comprising such an OLED, to the use of such a metal complex in OLEDs, for example as emitter, matrix material, charge transport material and/or charge or exciton blocker.
