A kind of difluoromethyleneoxy liquid crystal compound and its synthesis method |
| abstract |
The invention discloses a difluoromethyleneoxy liquid crystal compound and a synthesis method thereof. The fluorine-containing intermediate and phenylboronic acid are used as raw materials, and bis(triphenylphosphine) palladium dichloride is used as a catalyst in toluene. Fully reacted at reflux temperature and obtained after post-treatment. The difluoromethyleneoxy liquid crystal compound of the present invention has high optical anisotropy and dielectric anisotropy, high clearing point, low melting point and low viscosity, can be used for preparing liquid crystal mixture, and has broad application prospect. |
