Abstract
New halogenated ester derivatives and liquid crystal compositions containing the same are provided. The derivatives are expressed by the general formula ##STR1## wherein X is ##STR2## R is 1-15C alkyl group or alkoxy group; and Y is carboxyl group. The derivatives are useful as component(s) of liquid crystal compositions which have higher mesomorphic temperature ranges, nevertheless have lower viscosities; and also have lower absolute values of dielectric anisotropy, nevertheless can be driven at lower voltages.
Claims8
In a liquid crystalline admixture, the improvement wherein at least one component of said admixture is a halogenated ester derivative expressed by the general formula ##STR14## wherein X represents a group selected from the group consisting of ##STR15## R represents an alkyl group or an alkoxy group, each having 1 to 15 carbon atoms;
- and Y represents carboxyl group the symbol and the symbol being in a trans-configuration relative to cyclohexane or bicyclohexane ring.
