Abstract

Physical properties of several fluorinated diphenyldiacetylene and tolane liquid crystals are evaluated. These liquid crystals exhibit a high resistivity, high birefringence, low viscosity and modest dielectric anisotropy. Some difluoro compounds show a relatively low melting temperature and small heat fusion enthalpy, and are useful for formulating eutectic mixtures. The mixtures consisting of these fluorinated compounds are particularly useful for active matrix, photoactivated light valve, and polymerdispersed liquid crystal displays.
