Abstract: 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?2.

Abstract: A novel class of gold(III) compounds containing cyclometalated tridentate ligand and one aryl auxiliary ligand, both coordinated to a gold(III) metal center. (a) X is nitrogen or carbon; (b) Y and Z are independently nitrogen or carbon; (c) A is cyclic structure (derivative) of pyridine, quinoline, isoquinoline or phenyl group; (d) B and C are independently cyclic structures (derivatives) of pyridine, quinoline, isoquinoline or phenyl groups; (e) B and C can be identical or non-identical, with the proviso that both B and C are not 4-tert-butylbenzene; (f) R? is a substituted carbon, nitrogen, oxygen or sulfur donor ligand attached to the gold atom; (g) n is zero, a positive integer or a negative integer. wherein R? is selected from, but not limited to, aryl, substituted aryl, heteroaryl, substituted heteroaryl, heterocyclic aryl and substituted heterocyclic aryl, alkoxy, aryloxy, amide, thiolate, sulfonate, phosphide, fluoride, chloride, bromide, iodide, cyanate, thiocyanate or cyanide.
