    Abstract

    We have designed, synthesised and evaluated the physical properties of some high-birefringence (Delta n) isothiocyanato phenyl-tolane liquid crystals. These compounds exhibit Delta n similar to 0.48-0.52 at room temperature and wavelength lambda = 633 nm. Laterally substituted fluorine atoms eliminate smectic phases and lower the melting temperature. The moderate melting temperature and very high clearing temperature make those compounds attractive for eutectic mixture formulation.
