Abstract

The present invention provides complexes of the formula (L)M(X), in which M is a metal atom selected from copper, silver and gold; L is a carbene ligand; and X is a monoanionic ligand. The complexes are useful as light emitters in the emissive zone of light-emitting devices such as OLEDs. The present invention also provides organometallic complexes which exhibit RASI photoemission, and the use of the same in light-emitting devices such as OLEDs.
