Light emitting materials comprising novel ortho-metalated transition metal complexes |
| abstract |
This invention pertains to light emitting materials comprising novel ortho-metalated transition metal complexes [C^N] 2 ML comprising two orthometalated ligands having imidazole moieties and an ancillary ligand of β-diketonate type. The ortho-metalated transition metal complexes are represented by formula (I): n nIt has been surprisingly found that when the metal has bound thereto both orthometalated ligands comprising imidazole moieties and an ancillary ligand of β-diketonate type, the ligands advantageously participate in the emission process, significantly broadening emission in the visible region and enabling appreciable improvement of the white emission efficiency of complexes [C^N] 2 ML. Additional objects of the invention are the use of the light emitting materials and organic light emitting device comprising the light emitting material. |
