    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.

    Abstract translation: 在某些实施方案中，本发明提供具有式（I）的金属络合物：其中每个L x独立地是单齿配体，并且任意两个相邻的Lx可以任选地结合形成二齿配体; 其中M1是钴（I），铑（I），铱（I），镍（II），铂（II），钯（II），银（III），金（III）或铜（III） 其中m是可以连接到M1的配体的1至最大数量的值; 其中m + n是可以连接到M1的配体的最大数目; 其中G1是O或CR4R5; 并且R 1至R 5是各种取代基，其可任选地彼此结合，彼此之间或任何L x。 在某些实施方案中，本发明提供了包含这种金属络合物的装置，例如有机发光装置。
