Four series of new dimers formed by interlinking chalcone and cholesterol mesogenic entities through spacers of varying length and parity have been synthesized and characterized by polarizing optical microscopy, differential scanning calorimetry, X-ray diffraction and electrical switching studies. The structure of the chalcone core has been systematically modified to investigate the effect of the molecular structure on the thermal behaviour of the dimers. The study demonstrates the dramatic dependence of thermal behaviour of these dimers on the nature of the chalcone as well as the length and parity of the spacer. the Partner Organisations 2014.
Influence of fluoro substituents on the mesophase behaviour of banana-shaped molecules

, p. 2214 - 2220 (2007/10/03)
Three new series of bent-shaped five-ring liquid crystals, based on the ester of isophthalic acid as the central core and azomethine linkages, are presented. They differ by the number and the position of halogeno substituents on the outer rings. This lateral substitution strongly influences the type of mesophases formed. Calculations were performed to determine the modification of the distribution of charge along the different molecules.
Mesomorphic di- and tetra-fluorinated imines and their complexes with Re I

, p. 1555 - 1560 (2007/10/03)
The synthesis of some di- and tetra-fluoro imine mesogens is described and their mesomorphism is compared with that of the parent, unfluorinated materials. The comparison reveals that in the fluorinated compounds, more ordered smectic phases were suppress
