Title:
CIRCULARLY POLARIZED LIGHT-EMITTING MATERIAL AND USE, LIGHT-EMITTING DISPLAY DEVICE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/027411
Kind Code:
A1
Abstract:
Disclosed in the present invention are a helical-chiral tetradentate cyclometalated platinum (II) and palladium (II) complex circularly polarized light-emitting material based on phenyl-benzimidazole and a derivative thereof, and a use. The helical-chiral metal complex molecule can, by means of a central chiral segment La in a tetradentate ligand, autonomously induce the whole tetradentate ligand to coordinate with metal ions in a small steric hindrance manner to form an optically pure helical-chiral metal complex circularly polarized light-emitting material. The helical-chiral metal complex circularly polarized light-emitting material does not require chiral resolution, has high chemical stability and thermal stability, and has important applications in circularly polarized light-emitting elements.
