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. 

Liquid crystal compounds containing dibenzopyran derivatives of naphthenic base and application thereof

This invention relates to liquid crystal compound of formula I containing benzene derivatives group that hydrogen substituted by deuterium. Liquid crystal compounds of formula I have not only large positive dielectric anisotropy, but also moderate optical anisotropy and driving voltage, thereby having great significance to formulate a liquid crystal mixture. A liquid crystal mixture containing such type of liquid crystal compounds can be applied in various display devices, which is particularly suitable for TN and STN display devices, and can also be used in IPS and VA display devices. 

Liquid crystal compounds containing deuterium

This invention relates to liquid crystal compound of formula I containing a difluoromethyleneoxy linking group that hydrogen substituted by deuterium and therefore being very suitable for formulating a liquid crystal mixture. A liquid crystal mixture containing such type of liquid crystal compounds can be applied in various display devices.
