“…Thus, LC mixtures are required to have high clearing points and broad thermal range nematic phases. It has been reported that the replacement of aromatic rings with decalin rings often has advantageous effects on giving nematic phases with high crystal-nematic (Cr-N) transition temperatures, broad temperature range nematic phases and low viscosity (2)(3)(4)(5). The fluorine atom is generally used in the design of LC molecules to obtain many interesting effects, such as stronger dipole moment, lower viscosity and higher chemical stability (6)(7)(8).…”

2008) Synthesis and characterisation of nematic liquid crystals containing a trans-decalin ring, Liquid Crystals, 35:6, 665-673To link to this article: http://dx.The synthesis and mesomorphic behaviour of a series of liquid crystals incorporating a trans-decalin ring and two aromatic rings linked by esters are reported. Structures of the new compounds were confirmed by IR, 1 H NMR, 13 C NMR and elemental analysis. A single crystal of compound 18 was prepared to confirm the transconformation of the decalin ring. Liquid crystalline properties were investigated by differential scanning calorimetry and polarising optical microscopy. All of the synthesised compounds except 17e are found to show only an enantiotropic nematic phase over a wide temperature range.
