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

Abstract: The novel cyclopropylalkyl or -alkenyl compounds have the general formula In this formula, the symbols A , A , A denote unsubstituted and in particular substituted (by halogen or CN) aromatic or heteroaromatic molecular building blocks, such as 1,4-phenylene or pyrimidine-2,5- diyl, which are linked via a single bond or via functional groups M , M , such as CO-O or CH2-O; H and m are zero or 1; j, l, n are zero, 1 or 2. The radicals are R , R , R are H or alkyl/alkenyl, R is alkyl/alkenyl or a substituent known from LC chemistry, such as an alpha - haloalkanoic acid radical. G denotes alkylene or alkenylene.
