Title:
METHOD FOR SYNTHESIZING BTBF AROMATIC AMINE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2022/262310
Kind Code:
A1
Abstract:
The present invention provides a method for synthesizing BTBF aromatic amine derivatives, in which commercialized raw materials on the market are used, and after etherification, ring closure, bromination, and coupling reaction, target products, BTBF aromatic amine derivatives, are obtained. The method has the advantages of easily available raw materials, short route, high yield, simple purification process, and no need for column chromatography separation, is suitable for large-scale production, and is applicable to printing OLED devices because the obtained products have high purity and few impurities.
