Abstract: Imidazophenanthridine ligands and metal complexes are provided. The compounds exhibit improved stability through a linking substitution that links a nitrogen bonded carbon of an imidizole ring to a carbon on the adjacent fused aryl ring. The compounds may be used in OLEDs, particularly as emissive dopants in the emissive region in the OLEDs, providing devices with improved efficiency, stability, and manufacturing. In particular, the compounds provided herein may be used in blue devices having high efficiency.

Abstract: Compounds having the structure of Formula M(LA)x(LB)y and Formula III, are disclosed. In Formula M(LA)x(LB)y, Ligand LA is and ligand LB is a mono anionic bidentate ligand. In these compounds, metal M has an atomic number greater than 40; x is 1, 2, or 3; y is 0, 1, or 2; x+y is the oxidation state of metal M; L11 represents a linking group selected from alkyl, cycloalkyl, aryl, and heteroaryl; L12 represents a linking group selected from NR15 and PR15; each R1, R2, R3, R4, R5, R6, R11, R12, R13, R14, and R15 is independently selected from a group of substituents, wherein any adjacent substituents are optionally joined to form a fused or unfused ring; and LA and LB are optionally joined to form a ligand that is at least tetradentate. Formulations and devices, such as OLEDs, that include the compound of Formula M(LA)x(LB)y(LC)z are also described.
