Abstract
The present invention discloses liquid crystal compounds having dibenzopyran derivatives with cycloalkyl groups, and preparation methods and application thereof. The liquid crystal compounds having dibenzopyran derivatives with cycloalkyl terminal groups, shown in formula I, exhibit better miscibility and a very large negative dielectric constant, compared to those having a flexible alkyl chain as a terminal group, therefore the compounds of the present invention, shown in formula I, may improve the miscibility of liquid crystal compounds and broaden the application range of liquid crystal mixtures. In addition, the compounds may also increase the negative dielectric constants of liquid crystal mixtures, having an important application value.
