Title:
TETRADENTATE CYCLOMETAL PLATINUM(II) AND PALLADIUM(II) COMPLEX LUMINESCENT MATERIAL CONTAINING QUINOLINE STRUCTURAL UNIT AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/284486
Kind Code:
A1
Abstract:
The present invention relates to the technical field of organic luminescent materials, and provides a metal platinum (II) and palladium (II) complex luminescent material containing a quinoline structural unit, as shown below. Compared with a bidentate ligand platinum complex, the tetradentate ligand-based cyclometallated platinum (II) and palladium (II) complex provided by the present invention has strong molecular rigidity, and can effectively suppress nonradiative transitions due to molecular vibrations; moreover, quantum efficiency can be greatly improved; in addition, the present invention has broad application prospects in many fields such as OLED display and lighting.
