Abstract
Anisotropic compounds of the formula (1) ##STR1## wherein X and Y are each hydrogen, C.sub.1 -C.sub.12 alkyl, C.sub.1 -C.sub.12 alkoxy, N-monoalkaylamine having 1 to 12 carbon atoms in the alkyl group, halogen, cyano, nitro, or a cyclic radical of the formula ##STR2## wherein R is hydrogen, halogen, cyano, nitro, C.sub.1 -C.sub.12 alkyl, or C.sub.1 -C.sub.12 alkoxy, Z.sup.1 is a --COO-- group or a --OOC-- group and Z.sup.2 may be the same as Z.sup.1 or a single convalent bond, with the proviso that: PA1 (a) only one of the groups X and Y is a cyclic radical, and PA1 (b) neither of the groups X or Y is hydrogen, bromine, or poperidino when the other is hydrogen, have low .DELTA.n-values without a greay tendency to form smectic phases and are useful in preparing liquid crystal devices.
