Novel organic compounds containing a twisted aryl group are provided. In particular, the compounds provided contain a 2-phenylpyridine ligand having a twisted aryl group on the pyridine portion of the ligand. The compounds may be used in organic light emitting devices, particularly as emitting dopants. Devices comprising the compounds containing twisted aryl may demonstrate improved color, efficiency, stability and manufacturing. Additionally, methods are provided for making homoleptic Ir (III) compounds which may contain a twisted aryl.
提供了含有扭曲芳基团的新型有机化合物。具体来说,所提供的化合物包含在配体的吡啶部分上具有扭曲芳基团的2-苯基吡啶配体。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。含有扭曲芳基的化合物的器件可能表现出改善的颜色、效率、稳定性和制造工艺。此外,提供了制备可能含有扭曲芳基的同核铱(III)化合物的方法。
