    Abstract: Compounds comprising phosphorescent metal complexes comprising cyclometallated ligands having a structure of In the vgs3, each of the E1 atoms is selected from C and N, except that E1g is selected from C, N, and S. The E1 atoms collectively comprise an 18 pi-electron system, provided that E1a and E1p are different. The R1 substituents are each, independently, H, hydrocarbyl, heteroatom substituted hydrocarbyl, cyano, fluoro, OR2a, SR2a, NR2aR2b, BR2aR2b, or SiR2aR2bR2c, where the R2 substituents are each, independently, hydrocarbyl or heteroatom substituted hydrocarbyl. Any of the R1 or R2 substituents can be linked to form a saturated or unsaturated, aromatic or non-aromatic ring, provided that the R1 substituents are not present when the corresponding one of E atoms is N or S. Organic light emitting diode devices comprising these compounds are also described.
