Title: Luminescent gold(III) compounds containing bidentate ligand for organic light-emitting devices and their preparation
Usefulness: Luminescent gold(III) compounds containing bidentate ligand for organic light-emitting devices and their preparation
Summary: The luminescent gold(III) compounds are useful: in the light-emitting devices (all claimed), where the light-emitting devices include organic light-emitting devices, which are used in displays or solid state lighting applications; and as electrophosphorescent dopants in a multilayer organic light-emitting devices.
Novelty: New luminescent gold compound comprising a gold metal center, a bidentate ligand coordinating the metal center, and strong sigma-donating carbon donor group, useful in light-emitting devices including organic light-emitting devices
