Document Type and Number:
WIPO Patent Application WO/2021/249507
Kind Code:
A1
Abstract:
The present invention relates to the technical field of organic light-emitting materials, and provides a quadridentate ring metal platinum (II) complex based on carboxyl coordination and comprising pyridyl acridine and the use thereof; the quadridentate ring metal platinum (II) complex has a structure as shown in general formula (I); and in the quadridentate ring metal platinum (II) complex of the invention, a quadridentate ligand containing a strong field ligand of an oxygen anion is used, which has a strong coordination ability and large rigidity, and which can simultaneously improve the high quantum efficiency and optical stability thereof.
