Abstract: This invention pertains to light emitting materials comprising novel ortho-metalated transition metal complexes [C^N]2M(T)(L), comprising chelate dialkylamino-substituted C^N ligands, monodentate neutral ligand (L) having sp2 hybridized N atom and a monodentate anionic ligand (T) chosen among CN?, CNO?, CNS?. It has been surprisingly found that when the metal has bound thereto in addition to substituted orthometalated ligands, both an anion chosen among cyanide, thiocyanate, cyanate, possessing strong C donor and ? acceptor properties, and a monodentate neutral ligand L, as above defined, said ligands advantageously participate in the emission process, significantly shifting emission towards higher energies (blue-shift) and enabling appreciable improvement of the emission efficiency of complexes [C^N]2M(T)(L). Still objects of the invention are the use of said light emitting materials and organic light emitting device comprising said light emitting material.
