Abstract
The present invention provides a series of phosphorescent transition metal complexes having a facially arranged, carbon-phosphorus-carbon (C^P^C) tridentate chelate, alone with one monoanionic bidentate chromophoric chelate (either C^N or A^N) and one arbitrary charge neutral chelate (L), or with one charge neutral bidentate chromophoric chelate (N^N) and one arbitrary anionic ligand (X); all of them can be used to generate high efficiency photo-induced phosphorescence at room temperature, as well as bright electroluminescence upon employment of these materials in the fabrication of organic light-emitting devices.
