Imidazophenanthridine ligands and metal complexes are provided. The compounds exhibit improved stability through a linking substitution that links a nitrogen bonded carbon of an imidizole ring to a carbon on the adjacent fused aryl ring. The compounds may be used in organic light emitting devices, particularly as emissive dopants, providing devices with improved efficiency, stability, and manufacturing. In particular, the compounds provided herein may be used in blue devices having high efficiency.
提供了咪唑菲啉配体和金属配合物。这些化合物通过连接取代基展现出改善的稳定性,该连接将咪唑环的氮键合碳与相邻融合芳基环上的碳连接起来。这些化合物可以用于有机发光器件,特别是作为发射杂质,为设备提供改善的效率、稳定性和制造工艺。具体来说,本文提供的化合物可以用于具有高效率的蓝色器件。
