Abstract[English]
The present invention relates to the technical field of liquid crystal display materials, and in particular to a liquid crystal compound, a preparation method therefor, and a use thereof. The liquid crystal compound has a structure represented by the following general formula I: Formula (I). The liquid crystal compound having a specific structure of the present invention has advantages such as high dielectric anisotropy and good liquid crystal intersolubility. When the liquid crystal compound of the present invention is specifically applied to a liquid crystal composition, the dielectric anisotropy Δε of the liquid crystal composition can be significantly improved, and at the same time, appropriate refractive index anisotropy Δn is maintained. The obtained liquid crystal composition has significant fast response and low-voltage driving characteristics.[French]
