摘要:
Compounds containing 2-azatriphenylene are provided. In particular, compounds containing a 2-azatriphenylene core having an additional aromatic group are provided. The compounds provided may be emissive or non-emissive materials. The compounds may be used in organic light emitting devices, particularly as host materials, hole blocking layer materials, or emitting dopants. Devices comprising 2-azatriphenylene containing compounds may demonstrate improved stability and efficiency.
