ABSTRACT:
Compounds of the formula ##STR1## wherein X.sup.2 is a single covalent bond or --COO--; X.sup.1 is a single covalent bond, --COO--, --CH.sub.2 CH.sub.2 -- or when X.sup.2 is --COO--, X.sup.1 also can be p--C.sub.6 H.sub.4 --, p--C.sub.6 H.sub.4 --CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 --p--C.sub.6 H.sub.4, p--C.sub.6 H.sub.4 --COO-- or --COO--p--C.sub.6 H.sub.4 ; ring A is a benzene ring or trans-1,4-cyclohexylene; ring B is a benzene ring or when X.sup.2 is --COO-- and X.sup.1 is a single covalent bond, --COO-- or --CH.sub.2 CH.sub.2 --, ring B also can be trans-1,4-cyclohexylene; Z.sup.1, Z.sup.2 and Z.sup.3 individually are hydrogen or when positioned on a benzene ring which is not linked directly with a further ring via a single covalent bond, Z.sup.1, Z.sup.2 and Z.sup.3 also can be halogen, cyano or methyl; Y.sup.2 is cyano, nitro, 2,2-dicyanovinyl or when Y.sup.1 is hydrogen Y.sup.2 also can be 2,2-dicyano-1-methylvinyl; Y.sup.1 is halogen, cyano, C.sub.1 -C.sub.3 -alkyl or, when X.sup.1 includes a benzene ring of --COO-- or Y.sup.2 is nitro or at least one of Z.sup.1 and Z.sup.2 is other than hydrogen, Y.sup.1 also can be hydrogen; and R.sup.1 is C.sub.1 -C.sub.12 -alkyl or when positioned on a benzene ring R.sup.1 also can be C.sub.1 -C.sub.12 -alkoxy, their manufacture and use in liquid crystalline mixtures are described.
