LUMINESCENT CYCLOMETALATING TRIDENTATE LIGAND-CONTAINING GOLD (III) COMPOUNDS WITH ARYL AUXILIARY LIGANDS FOR ORGANIC LIGHT-EMITTING DEVICES AND THEIR PREPARATION THEREOF

WIPO Patent Application WO/2018/064974

A1

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) Ais cyclic structure (derivative) ofpyridine, 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, apositive 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. Rings A, B and C are independently benzene or pyridine, or aryl (derivatives) or pyridyl, quinolyl, isoquinolyl (derivatives) with, but not limited to, one or more alkyl, alkenyl, alkynyl, alkylaryl, cycloalkyl, OR, NR2, SR, C (O) R, C (O) OR, C (O) NR2, CN, CF3, NO2, SO2, SOR, SO3R, halo, aryl, substituted aryl, heteroaryl, substituted heteroaryl or heterocyclic group, wherein R is independently alkyl, alkenyl, alkynyl, alkyaryl, aryl, or cycloalkyl.
