Abstract
In certain embodiments, the invention provides metal complexes having Formula (I):wherein each Lx is independently a monodentate ligand, and any two adjacent Lx may optionally combine to form a bidentate ligand; wherein M1 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 M1; wherein m+n is the maximum number of ligands that may be attached to M1; wherein G1 is O or CR4R5; and R1 to R5 are various substituents, which can optionally combine with each other, among themselves, or with any Lx. In certain embodiments, the invention provides devices, such as organic light emitting devices, that comprise such metal complexes.
