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 1):
A compound having a structure (L A ) n ML m  according to Formula 1: wherein M is a metal having an atomic weight greater than 40, n has a value of at least 1 and m+n is the maximun number of ligands that may be attached to the metal; wherein A is a linking group selected from the group consisting of \u2014CR\u2032R\u2033\u2014CR\u2032R\u2033\u2014, \u2014CR\u2032R\u2032\u2014CR\u2033R\u2033\u2014, and \u2014CR\u2032R\u2032\u2014CR\u2032R\u2032\u2014CR\u2032R\u2032\u2014; wherein each R\u2032 is independently selected from the group consisting of H, D, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof, wherein each R\u2033 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, heteroaryl, partially or fully deuterated variants thereof, and combinations thereof, wherein R\u2032s and R\u2033s are optionally connected to form a saturated five membered ring or a saturated six membered ring, and combinations thereof, wherein R 1a  to R 1g  are each independently selected from the group consisting of hydrogen, deuterium, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; wherein any one of the ring atoms to which R 1b  to R 1g  are attached may be replaced with a nitrogen atom, wherein when the ring atom is replaced with a nitrogen atom the corresponding R group is not present; wherein L is a substituted or unsubstituted cyclometallated ligand, wherein L can be joined to R 1g  through a linking group L 2 ; wherein L 2  is selected from the group consisting of a single bond, NR, O, S, CR 1 R 2 , and SiR 1 R 2 ; wherein R, R 1 , and R 2  can be same or different, and are independently selected from the group consisting of hydrogen, deuterium, alkyl, cycloalkyl, aryl, heteroaryl, and combinations thereof; wherein any adjacent R 1  and R 2  are optionally connected to form a saturated five membered ring or a saturated six membered ring.
