    摘要: 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.

    摘要: In certain embodiments, the invention provides metal complexes having Formula (I):

    wherein each L x is independently a monodentate ligand, and any two adjacent L x may optionally combine to form a bidentate ligand; wherein M 1 is cobalt(I), rhodium(I), iridium(I), nickel(II), platinum(II), palladium(II), silver(III), gold(III), or copper(III); wherein m is a value from 1 to the maximum number of ligands that may be attached to M 1 ; wherein m+n is the maximum number of ligands that may be attached to M 1 ; wherein G 1 is O or CR 4 R 5 ; and R 1 to R 5 are various substituents, which can optionally combine with each other, among themselves, or with any L x . In certain embodiments, the invention provides devices, such as organic light emitting devices, that comprise such metal complexes.
