Abstract
Optically active 1,3-dioxolane-4-carboxylic acid esters and oxirane-2-carboxylic acid esters of the general formula (I) <IMAGE> where R<1> is, for example, C1-C16-alkyl or C1-C16-alkoxy, A<1>, A<2> and A<3> are, for example, phenyl or pyrimidine-2,5-diyl, M<1> and M<2> are, for example, CO-O or CH2-CH2, j and l are 0, 1 or 2, k and m are 0 or 1, n is 0, 1 or 2, X is O or S and Ac is <IMAGE> or where R<2>, R<3>, R<4>, R<5> and R<6> are, for example, H or methyl, are particularly suitable doping agents for liquid-crystalline mixtures since they induce a high spontaneous polarisation and considerably reduce the melting point.
