Abstract: Optically active tetrahydrofuran-2-carboxylic acid esters containing a mesogenic molecular building block are suitable as dopes in liquid-crystal mixtures. They result in liquid-crystalline ferroelectric phases having short switching times and in electroclinic phases having high electroclinic coefficients. A further advantage is that they induce a helix of very low pitch, so they are also suitable for helix compensation in LC mixtures. The compounds are symbolised by the general formula in which the symbols and indices essentially have the following meanings: R = alkyl/alkenyl or tetrahydrofurancarbonyloxy or -thio; j, l and n = zero, 1 or 2; k and m = zero or 1; -A , -A and -A = phenylene, cycloalkylene or corresponding N-, O- or S-containing heterocycles; -M and -M = bridges, such as -CO-O-, -OCH2- or -CH=CH-; and X = O or S.

Abstract: The liquid crystalline cyclopropylalkyl or -alkenyl heterocycles have the formula in which the symbols A , A , A are aromatic or heteroaromatic molecular building blocks, such as 1,4-phenylene or pyrimidin-2,5-diyl which are linked via a single bond (if k,m are zero) or via functional groups M , M , such as CO-O or CH2-O; j, k, l, m, n are zero or 1 (j+l+n = 2 or 3). The radicals R , R , R are H or alkyl/alkenyl, R is alkyl/alkenyl or one of the substituents known from LC chemistry, such as an alpha -haloalkanoic radical. In addition, at least one of the building blocks A , A , A must be heteroaromatic and G denotes alkylene or alkenylene.
