  A negative dielectric anisotropic liquid crystal compound containing 2,3-difluorophenyl, and a preparation method and use thereof are disclosed. The compound has a general structural formula as shown in Formula I. The negative dielectric anisotropic liquid crystal compound has a negative dielectric anisotropy (Δε), and has cyclobutyl or cyclopentyl as a terminal group. Compared with conventional liquid crystal compounds with a flexible alkyl chain as a terminal group, the compound of Formula I according to the present invention has the advantage of high clearing point, and enables extension of the application range of a liquid crystal mixture because a positive correlation exists between the clearing points of the liquid crystal mixture and monomer liquid crystal compounds. In addition, the compound can increase the absolute value of the negative dielectric constant of the liquid crystal mixture, thus having an important application value.
