ABSTRACT:
A compound of the formula (I) is describedwhere R1and R2are defined in the specification and p=q=r=0or 1 with p+q+r≠0. The compound of formula (I) has high dielectric anisotropy, thermally stable, fast response time and high voltage holding ratio, which is used as a liquid crystal medium for the liquid-crystal displays such as ECB, in-plane-switching (IPS) and VA display mode.
