More Information
Summary:A new class of compounds containing aza-dibenzothiophene or aza-dibenzofuran are provided. The compounds may be used in organic light emitting devices giving improved stability, improved efficiency, long lifetime and low operational voltage. In particular, the compounds may be used as the host material of an emissive layer having a host and an emissive dopant, or as a material in an enhancement layer.
