Title:
TETRADENTATE ONCN PLATINUM COMPLEX CONTAINING MULTIPLE N-HETEROCYCLES
Document Type and Number:
WIPO Patent Application WO/2022/148101
Kind Code:
A1
Abstract:
The present invention relates to a tetradentate ONCN platinum complex containing multiple N-heterocycles, which has a structural formula as represented by formula (I). By means of the introduction of the multiple N-heterocycles in the compound, the electron cloud density of molecules is dispersed, such that the order arrangement of the molecules is avoided during purification. Compared with the previous pyridine structure, the electron cloud density is higher, such that on the one hand, the coordination binding capacity is improved, and the stability of the molecules is improved, and on the other hand, the electron cloud density near the metal platinum on the parent ring is enhanced, and the efficient luminous efficiency is obtained; and the steric hindrance of molecules is increased by the R1-R5 groups on a right benzene ring, such that the aggregation of the molecules is effectively reduced.
