ABSTRACT:
The new compounds produced from a molecular structural element with two chirality centers and at least one mesogenic structural element are defined by the general formula (I) ##STR1## in which the symbols have the following meaning: Y.sup.1, Y.sup.2, Y.sup.3, Y.sup.4 = in any two cases (a) hydroxy and MC--CO--O or, independently of each other, MC--CO--O and (b), independently of each other (C.sub.1 -C.sub.10)alkoxy, MC denoting the molecular radical of a mesogenic carboxylic acid after splitting off a COOH group, and it being possible for Y.sup.2 and Y.sup.3, in the case of (C.sub.1 -C.sub.10)alkoxy, also to be jointly part of a dioxolane ring, or Y.sup.1 and Y.sup.4 jointly = 0 as part of a tetrahydrofuran ring, and Y.sup.2 and Y.sup.3 = hydroxy and MC--CO--O or, independently of each other, MC--CO--O. Said esters preferably find application as dopants in twistable liquid crystal phases in which they produce temperature compensation and twisting.
