Described herein are two-coordinated d10 metal carbene complexes containing (i) Cu(I), Ag(I), or Au(I), (ii) a pyrazine-fused NHC ligand or a pyridine-fused NHC ligand, and (iii) a carbazole ligand, a pyrido[2,3-b]indole ligand, or a pyrido[3,4-b]indole ligand. The radiative properties of the compounds can be controlled by thermally activated delayed fluorescence. The emission colors of the complexes can be tuned by using carbazoles with varying donor strength. Also described are methods of using the complexes.

A series of thermally stable and highly luminescent cyclometalated tetradentate ligand-containing gold(III) compounds was designed and synthesized. The cyclometalated tetradentate ligand-containing gold(III) compounds can be used as light-emitting material for fabrication of light-emitting devices. The cyclometalated tetradentate ligand-containing gold(III) compounds can be deposited as a layer or a component of a layer using a solution-processing technique or a vacuum deposition process. The cyclometalated tetradentate ligand-containing gold(III) compounds are robust and can provide electroluminescence with high efficiency and brightness. More importantly, the vacuum-deposited OLEDs demonstrate long operational stabilities with half-lifetime of over 29,700 hours at 100 cd m.sup.−2.

A method of manufacturing of an ink (100) composition comprises a biphasic ligand exchange process. A first phase liquid (10) comprising a nonpolar solvent (11) with a colloidal suspension of nanoparticles (1) that are capped with a shell of non polar ligands (2) is contacted with a second phase liquid (20) comprising a polar solvent (21) with second ligand (3). The second ligand comprises at least one surface binding head group that has an affinity for binding to the nanoparticle; and an ionically charged tail group. The second ligands displace the first ligands to form a dispersion of the nanoparticles that are capped with a shell of the second ligands in the second phase liquid. The nanoparticles can be separated from the second phase liquid. The separated nanoparticles can be (re)dispersed in a printable liquid medium, e.g. used for printing a photoactive layer.
