Abstract
A novel class of gold (III) compounds with thermally stimulated delayed phosphorescence (TSDP) properties, methods of making and use thereof are disclosed. The gold (III) compound includes a triazine-containing cyclometalating tridentate ligand and one auxiliary ligand, both coordinated to a gold (III) metal center. The gold (III) compounds can be used as light-emitting material for fabrication of OLEDs. A novel concept of TSDP to harvest light emission from the higher energy triplet excited state via the up-conversion from the lowest-energy triplet excited state by efficient spin-allowed reverse internal conversion is also disclosed.
