Abstract:
An organic light emitting device that includes an anode, a cathode, an enhancement layer, and an emissive layer that includes homoleptic iridium complexes containing phenyl-imidazole ligands, which include at least one fused substituent. The enhancement layer also includes a new dibenzothiophene and dibenzofuran-containing compound that is useful as a material in an enhancement layer.
