Abstract

The liquid crystalline cyclopropylalkyl or -alkenyl heterocycles have the formula <IMAGE> in which the symbols A<1>, A<2>, A<3> 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<1>, M<2>, 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<2>, R<3>, R<4> are H or alkyl/alkenyl, R<1> 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<1>, A<2>, A<3> must be heteroaromatic and G denotes alkylene or alkenylene.
