Abstract
A liquid crystal compound containing cyclobutyl and a linking group difluoromethyleneoxy, and a preparation method and use thereof are disclosed. The compound is as shown in Formula I. The liquid crystal compound containing cyclobutyl as a terminal group and difluoromethyleneoxy (—CF2O—) as a linking group in the molecular structure of Formula I according to the present invention, has not only a high dielectric anisotropy, but also importantly an extremely fast response speed and a high clearing point, which are of great significance for the formulation of a liquid crystal mixture.
