Abstract: 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.

Abstract: Organometallic compounds comprising an imidazole carbene ligand having a N-containing ring fused to the imidazole ring are provided. In particular, the N-containing ring fused to the imidazole ring may contain one nitrogen atom or more than one nitrogen atom. These compounds may demonstrate high photoluminescent (PL) efficiency, Gaussian emission spectra, and/or short excited state lifetimes. These materials may be especially useful as blue phosphorescent emitters.
