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: Phenylpyrimidinyl trans-cyclohexanecarboxylates of the formula … … form, in addition to a relatively broad nematic phase, a smectic C phase if R denotes an alkyl radical having 10 to 16 carbon atoms, in particular 11 to 16 carbon atoms, or an alkyloxy radical having 8 to 14 carbon atoms and R denotes an alkyl radical having 2 to 9 carbon atoms. Accordingly, they are suitable in particular as components of liquid-crystalline mixtures having a smectic C phase, since they induce a relatively broad nematic phase or widen a narrow nematic phase present and enlarge the temperature range of the smectic C phase towards low, but in particular towards high temperatures.
