introduction | 4-bromo -2, 6-difluorophenol, also called 2, 6-difluoro-4-bromophenol, is an important intermediate used to synthesize a variety of liquid crystal monomers. on the one hand, it can undergo etherification reaction with halogen-containing benzene ring, on the other hand, fluorine-containing liquid crystal monomers with different properties can be prepared by coupling reaction with a variety of boric acids. These liquid crystal monomers have the advantages of low viscosity, high resistivity, fast response speed, and can improve the dielectric constant of mixed crystals. It is very suitable for liquid crystal displays driven by thin film field effect transistors. |
