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.
