Abstract

Different structures of laterally fluorinated tolane and diphenyl-diacetylene liquid crystals were synthesized and their physical properties evaluated. Some of these compounds exhibit relatively low melting temperature, small heat fusion enthalpy, large negative dielectric anisotropy and high resistivity. The fluoro-tolanes possess a modest birefringence and are useful for high contrast displays employing a homeotropic alignment. On the other hand, the fluoro diphenyl-diacetylenes have a larger birefringence. Their potential applications are in the infrared spatial light modulators and millimeter wave phase shifters.
