Embodiment Construction

[0078]We describe a class of luminescent bicoordinated metal(I)carbenes with planar or twisted geometries surrounding the metal (ie, out-of-plane opposing coordination ring systems). Metal (I) is selected from Cu(I), Ag(I) and Au(I). The compound can be further described as a combination of a monodentate carbene ligand and a monodentate neutral ligand, or a combination of a monodentate carbene ligand and a monodentate monoanionic ligand, to provide an overall cationic or neutral charge, respectively. double-coordinated metal(I) compounds. Exemplary families of carbene include cyclic alkylaminocarbene (CAAC), as well as conventional and unconventional N-heterocyclic carbene ligands, such as imidazol-2-ylidene (BzI), monoamido-aminocarbene (MAAC) and diaminocarbene (DAC).

[0079] In general, an OLED comprises at least one organic layer which is disposed between and electrically connected to an anode and a cathode. When a current is applied, the anode injects holes and the ca...

Abstract

The invention relates to carbene compounds and organic electroluminescent devices. A compound selected from the group consisting of Formula I, Formula II, and Formula III, wherein ring A, ring B, andring C are independently a five-membered or six-membered, carbocyclic or heterocyclic ring, each of which is optionally aromatic; ring W of Formula I is a 6-membered heterocyclic ring, and ring W of Formula II or Formula III is a 5-membered or 6-membered heterocyclic ring; L is a mono-dentate ligand with a metal coordinating member selected from the group consisting of C, N, O, S, and P; and M isa metal selected from the group consisting of Cu, Au, and Ag.
