Title:
LUMINESCENT GOLD (III) COMPOUNDS WITH THERMALLY ACTIVATED DELAYED FLUORESCENCE (TADF) AND THERMALLY STIMULATED DELAYED PHOSPHORESCENCE (TSDP) PROPERTIES FOR ORGANIC LIGHT-EMITTING DEVICES AND THEIR PREPARATION
Document Type and Number:
WIPO Patent Application WO/2022/237348
Kind Code:
A1
Abstract:
Described herein is a novel concept of the realization of thermally activated delayed fluorescence (TADF) and thermally stimulated delayed phosphorescence (TSDP) to harvest light emission from the higher-energy singlet and triplet excited states via the up-conversion from the lowest-energy triplet excited state by efficient reverse internal conversion together with reverse intersystem crossing as well as the development of emitters with TADF and TSDP properties, as exemplified by a new class of gold (III) compounds with TADF and TSDP properties. The gold (III) compounds include N-heterocycle-containing cyclometalating tridentate ligand and one auxiliary ligand, both coordinated to a gold (III) metal centre and having the chemical structure shown in generic formula (I).
