Novel heteroleptic iridium complexes having the structure of Formula I,
are provided. In Formula I, X is selected from the group consisting of NR, BR, and Se; R is selected from hydrogen and alkyl, and each R1, R2, R3, and R4 is independently selected from hydrogen, alkyl, and aryl. The compounds may be used in organic light emitting devices, particularly as emitting dopants, to provide devices having improved efficiency, lifetime, and manufacturing.
