Title:
Liquid crystal compounds with difluoromethoxy crosslinks, compositions and their applications
Document Type and Number:
Japanese Patent JP6306270
Kind Code:
B2
Abstract:
The present invention relates to a liquid crystal compound of a structure as represented by formula I, where R is selected from H and alkyls or alkoxies that are either unsubstituted or have one or multiple H being substituted by halogens and contain 1-12 carbon atoms, A1 is selected from single bond or 1,4 phenyl groups, wherein the H in the 1,4 phenyl group can independently be substituted by one or multiple halogens, L1 and L2 are independently selected from H or halogens, and Z1 is selected from a single bond or a -(CH2)-. The compound of the present invention has the characteristics of low rotational viscosity, large dielectric anisotropy, great miscibility, and stable performance, allows a reduced drive voltage for a component when applied to a composite, and has a broad application prospect.
