Synthesis and mesomorphic properties fluoro- and chloro-substituted isothiocyanatotolanes

We report the synthesis procedures, phase transition temperatures, optical and dielectric properties of the fluoro and chloro -- substituted two rings and three rings isothiocyanatotolanes. Three eutectic mixtures comprising of these isothiocyanatotolane compounds showing a wide nematic range, low viscosity and high birefringence (~0.4) are formulated.
