Abstract

We have designed, synthesized, and evaluated the physical properties of some high birefringence (n) isothiocyanato biphenyl-tolane liquid crystals. These compounds exhibit n0.48-0.52 at room temperature and wavelength =633nm. Laterally substituted short alkyl chains and fluorine atom eliminate smectic phase and lower the melting temperature. The moderate melting temperature and very high clearing temperature make those compounds attractive for eutectic mixture formulation. A eutectic mixture based on those compounds was formulated and its physical properties evaluated.
