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 20):
A compound having a structure according to Formula A: wherein M is Ir; wherein n is 3; wherein A is a linking group selected from the group consisting of \u2014CR\u2032R\u2033\u2014CR\u2032R\u2033\u2014 and \u2014CR\u2032R\u2032\u2014CR\u2033R\u2033\u2014; wherein each or R\u2032 and R\u2033 is independently selected from the group consisting of undeuterated alkyl, partially deuterated alkyl, and fully deuterated alkyl; 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 R 1a  is selected from the group consisting of H, non-deuterated phenyl, partially deuterated phenyl, and fully deuterated phenyl; wherein R 1d  is selected from the group consisting of H, \u2014CH 3 , \u2014CD 3 , and isopropyl; and wherein R 1f  is selected from the group consisting of H, \u2014CH 3 , \u2014CD 3 , and isopropyl.
