    • 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 sp 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.
    • 本发明涉及包含新型邻位金属化过渡金属络合物[C 3 N] 2M(T)(L))的发光材料,其包含螯合二烷基氨基取代的C 1 N配体,具有sp杂化的N原子的单齿中性配体(L) 选自CN,-CNO-,CNS-的单齿阴离子配体(T)。 已经令人惊奇地发现,除了取代的正交金属配体之外,当金属与其结合时,选自具有强c供体和“受体性质”的氰化物,硫氰酸盐,氰酸盐和如上所定义的单齿中性配体L的阴离子, 所述配体有利地参与发射过程,将发射显着地转移到更高的能量(蓝移)并且使复合物[C ^ N] 2M(T)(L)的发射效率明显改善。 本发明的另一个目的是使用所述发光材料和包括所述发光材料的有机发光器件。
