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.
本研究提供了咪唑菲啶配体和金属配合物。通过将咪唑环上的氮键碳与相邻融合芳基环上的碳连接起来的连接取代作用,这些化合物显示出更高的稳定性。这些化合物可用于有机发光器件,特别是作为发光掺杂剂,从而提高器件的效率、稳定性和制造性能。特别是,本文提供的化合物可用于具有高效率的蓝色器件中。
