Novel heteroleptic iridium complexes are disclosed. The complexes contain a phenyl pyridine ligand and another ligand containing a dibenzofuran, dibenzothiophene, dibenzoselenophene, or carbazole linked to an imidazole or benzimidazole fragment. These complexes are useful materials when incorporated into OLED devices.
Novel asymmetric host compounds containing an electron-transport moiety, a hole-transport moiety, an aromatic spacer, and a triaryl silane group are provided. These compounds are useful materials that can be incorporated into OLED devices.
Novel phosphorescent metal complexes containing 2-phenylisoquinoline ligands with at least two substituents on the isoquinoline ring are provided. The disclosed compounds have low sublimation temperatures that allow for ease of purification and fabrication into a variety of OLED devices.

Novel diarylamino phenyl carbazole compounds are provided. By appropriately selecting the nature of the diarylamino substituent and the substitution on the carbazole nitrogen, compounds with appropriate HOMO and LUMO energies can be obtained for use as materials in a secondary hole transport layer.
Novel metal complexes containing silyl substitution are provided. Depending on the location of the substitution, compounds that emit in the yellow or green portions of the spectrum can be produced. These compounds are useful as components of OLED devices.
