Abstract

Anisotropic compounds having a nematic phase have the formula ##STR1## wherein R.sup.1, R.sup.2, A, Z, X and n are described in the specification. Compounds having the defined lateral substituents on the rings have a reduced tendency to form smectic phases as compared with the compounds not having such lateral substituents.
