Title:
PREPARATION AND USE OF TETRADENTATE PLATINUM(II) COMPLEX
Document Type and Number:
WIPO Patent Application WO/2021/233147
Kind Code:
A1
Abstract:
The present invention relates to the preparation and use of a novel tetradentate platinum(II) complex, and belongs to the field of OLED organic electroluminescent materials. The complex of the present invention has an NCNC chelating coordination, a stable structure, a spiro ring structure in the skeleton, a strong molecular stereoscopic property, and a weak intermolecular interaction, thereby avoiding the occurrence of mutual stacking between the complex molecules, greatly inhibiting the formation of an excimer, and thus improving the efficiency of an OLED device. The complex of the present invention has a high fluorescence quantum efficiency, a good heat stability and a low quenching constant, and can be used for manufacturing a red-light OLED device with a high luminous efficiency and a low roll-off.
