The synthesis of three different chiral short molecular weight compounds have been reported. The overall compounds incorporate a linear perfluorinated tail and S-ethyl-Iactate as chiral moiety. Each compound differ to the other by one molecular parameter: a spacer carbonyloxy or oxycarbonylmethoxy or by the presence or not of an ester function between the two aromatic rings of the mesogenic core. The synthesis have been carried out from 2-F-hexylethyliodide or 2-F-hexylethanol. The mesomorphic properties have been characterized by light microscopy and by differential thermal analysis showing the peculiar effect of the spacer. The two biphenyl derivatives exhibit liquid crystal properties over a wide temperature range. The mesophase for both compounds is smectic of type A. However, the introduction of an ester function in the core contribute to enhance the melting temperature and suppress the liquid crystal behavior.
