BIPYRIDINE METAL COMPLEXES FOR USE AS LIGHT-EMITTING MATERIAL |
摘要 |
The present invention relates to light emitting materials comprising novel ortho-metalated transition metal complexes [C^N]2M[N^N] comprising two orthometalated ligands (C^N ligands) and a neutral bidentate bipyridine ligand (N^N). Surprisingly, it has been found that when the metal binds both orthometalated chelate C^N ligands and a neutral bidentate bipyridine ligand (N^N), said ligands participate in the emission process, thus greatly improving the red emission efficiency of complexes [C^N]2M[N^N]. The present invention further relates to the use of said light emitting materials and an organic light emitting device comprising said light emitting material.
