Abstract
Isothiocyanato tolane liquid crystals exhibit a high birefringence and relatively low viscosity. The phase transition temperatures, birefringence and visco-elastic coefficient of several high birefringence isothiocyanato tolane compounds are evaluated. Using these compounds, several eutectic mixtures were formulated. These new mixtures exhibit a wide nematic range, high birefringence (>0.4) and low viscosity.
