Abstract:

Compounds comprising phosphorescent metal complexes comprising cyclometallated ligands having a structure ofIn the vgs3, each of the Eatoms is selected from C and N, except that Eis selected from C, N, and S. The Eatoms collectively comprise an 18 pi-electron system, provided that Eand Eare different. The Rsubstituents are each, independently, H, hydrocarbyl, heteroatom substituted hydrocarbyl, cyano, fluoro, OR, SR, NRR, BRR, or SiRRR, where the Rsubstituents are each, independently, hydrocarbyl or heteroatom substituted hydrocarbyl. Any of the Ror Rsubstituents can be linked to form a saturated or unsaturated, aromatic or non-aromatic ring, provided that the Rsubstituents 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.
