20110121279 | Light-emitting material comprising multinuclear complexes - Light emitting materials comprising multinuclear metal complexes comprising at least two metal atoms and a metal bridging ligand bound to said at least two metal atoms. It relates more particularly to a multinuclear complex of Formula (I): {-[L]2M-B-}n, wherein L is a bidentate ligand; M represents a transition metal having an atomic number of at least 40, and each M can be the same or different at each occurrence; B is a 2-connecting short metal bridging ligand bound to said at least two metal atoms, where the metal bridging ligand comprises coordinating atoms independently selected from the group consisting of nitrogen, phosphorous, carbon, oxygen, sulphur and selenium in 1,2 or 1,3 mutual position.(1,2-μ or 1,3-μ bonding mode); and n is an integer larger than 1. | 05-26-2011 |
20110215276 | Phosphorescent light-emitting material - The present invention relates to light emitting materials including a novel Ir complex, where the Ir is provided with a primary ligand selected from phenyl pyridine ligands substituted with at least one Cl atom. Such light emitting materials have been found to have a significantly enhanced photoluminescence quantum yield over other Ir complexes with a phenyl pyridine ligand having no Cl atom, or even over those with a phenyl pyridine ligand having a halogen atom other than Cl, such as a Br or F atom, and as a result specifically improve the efficiency of a light emitting device. The present invention further relates to the use of such light emitting materials and an organic light emitting device including such light emitting materials. | 09-08-2011 |
