Abstract
Novel trans(equatorial-equatorial)1,4-disubstituted cyclohexane derivatives of the general formula ##STR1## wherein R represents a linear alkyl group containing 3 to 7 carbon atoms, and R' represents a linear alkoxy group containing 2 to 5 carbon atoms or a cyano group. These compounds are nematic liquid crystals, and a composition containing at least one of these compounds is useful as an electro-optical display material.
Claims25
A trans(equatorial-equatorial)1,4-disubstituted cyclohexane derivative of the general formula ##STR249## wherein R represents a linear alkyl group containing 3 to 7 carbon atoms and R' represents a linear alkoxy group containing 2 to 5 carbon atoms or a cyano group.
A nematic liquid crystalline composition comprising at least two trans(equatorial-equatorial)1,4-disubstituted cyclohexane derivatives, which are nematic liquid crystalline compounds, of the general formula ##STR250## wherein R represents a linear alkyl group containing 3 to 7 carbon atoms, and R' represents a linear alkoxy group containing 2 to 5 carbon atoms or a cyano group.
A nematic liquid crystalline composition comprising at least one trans(equatorial-equatorial)1,4-disubstituted cyclohexane derivative, a nematic liquid crystalline compounds, of the general formula ##STR251## wherein R represents a linear alkyl group containing 3 to 7 carbon atoms, and R' represents a linear alkoxy group containing 2 to 5 carbon atoms or a cyano group, and at least one additional component selected from the group consisting of other nematic liquid crystalline compounds and homologs thereof which are not liquid crystalline.
