摘要： Compounds including a ligand with a dibenzo-fused 5-membered ring substituent are provided. In particular, the compounds may be iridium complexes including imidazole coordinated to the dibenzo-substituted ligand. The dibenzo-fused 5-membered ring moiety of the ligand may be twisted or minimally twisted out of plane with respect to the rest of the ligand structure. The compound may be used in organic light emitting devices, particularly as emitting dopants in blue devices. Devices comprising the compounds may demonstrate improved stability while maintaining excellent color.

摘要： 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.
