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.

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.
