CENTRAL CHIRALITY INDUCED SPIRO CHIRAL TETRADENTATE CYCLOMETALATED PLATINUM (II) AND PALLADIUM (II) COMPLEX-BASED CIRCULARLY POLARIZED LUMINESCENCE MATERIAL AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/218399

Kind Code:

A1

Abstract:

Disclosed are a central chirality induced spiro chiral tetradentate cyclometalated platinum (II) and palladium (II) complex-based circularly polarized luminescence material and an application thereof. Spiro chiral metal complex molecules can autonomously induce the whole tetradentate ligand to coordinate with metal ions in a less sterically hindered manner by means of a central chiral fragment La in the tetradentate ligand, to form an optically pure spiro chiral metal complex-based circularly polarized luminescence material, without the need for chiral resolution. Moreover, the material has high chemical stability and thermal stability, and has important applications in circularly polarized luminescence elements.
