Abstract

A new class of dibenzothiophene, dibenzofuran and/or carbazole-containing compounds are provided. The new compounds may be useful in organic light emitting devices, particularly as the host of an emissive layer having a host and an emissive dopant, or as a material in an enhancement layer.
