Abstract: 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.

Abstract: An OLED includes a suppression mechanism and multiple dopants in its organic emissive layer. The organic emissive layer includes a host, a first compound capable of phosphorescent emission at room temperature, and a second compound capable of phosphorescent emission at room temperature. The suppression mechanism is capable of preferentially reducing the emission of light emitted by the second compound. The organic emissive layer may also contain a third compound capable of phosphorescent emission at room temperature.
