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 organic light emitting devices, particularly as emissive dopants, providing devices with improved efficiency, stability, and manufacturing. In particular, the compounds provided herein may be used in blue devices having high efficiency.

Claim (Index 16):
The compound of  claim 1 , wherein the ligand L is selected from the group consisting of: wherein each X 1  to X 13  are independently selected from the group consisting of carbon and nitrogen; wherein each R a , R b , R c , and R d  may represent from mono substitution to the possible maximum number of substitution, or no substitution; wherein R a , R b , R c , and R d  are each independently selected from the group consisting of hydrogen, deuterium, halide, alkyl, cycloalkyl, heteroalkyl, arylalkyl, alkoxy, aryloxy, amino, silyl, alkenyl, cycloalkenyl, heteroalkenyl, alkynyl, aryl, heteroaryl, acyl, carbonyl, carboxylic acids, ester, nitrile, isonitrile, sulfanyl, sulfinyl, sulfonyl, phosphino, and combinations thereof; and wherein any two adjacent substituents of R a , R b , R c , and R d  are optionally fused or joined to form a ring or form a multidentate ligand.
