Abstract

Disclosed are liquid crystal compounds of cycloalkyl-containing dibenzofuran derivatives, a preparation method therefor and use thereof. The compounds are as represented by formula I. In the molecular structures of the compounds of formula I provided by the present invention, liquid crystal compounds of cycloalkyl terminal group-containing dibenzofuran derivatives, compared with those having flexible alkyl chains as terminal groups, exhibit better intersolubility, and thus the use of a compound as represented by formula I provided by the present invention can improve the intersolubility of a liquid crystal compound and extend the application range of a liquid crystal mixture, producing an important application value.
