Abstract: An organic light emitting device (OLED) is provided. The OLED has an anode, a cathode, and an emission layer, disposed between the anode and the cathode, including a first emitting compound; wherein the first emitting compound is capable of functioning as a blue phosphorescent emitter in the OLED at room temperature; wherein the first emitting compound has PLQY of less than 90% at room temperature; wherein the OLED has an external quantum efficiency of between 8% and 20% at 1 mA/cm2.

Abstract: 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.
Abstract translation: 提供了咪唑苯胺配位体和金属配合物。 化合物通过将亚胺唑环的氮键合碳与相邻稠合芳基环上的碳连接的连接取代表现出改进的稳定性。 这些化合物可以用于有机发光器件，特别是作为发射掺杂剂，提供具有改进的效率，稳定性和制造的器件。 特别地，本文提供的化合物可以用于具有高效率的蓝色装置中。
