Abstract

Physical properties of mono-, di- and tri- fluorobenzenc derivatives with different core structures consisting of 3-ring system were measured. By introduction of fluorine atoms, phase change telnperaturcs decreased, nematic temperature range narrowed, optical anisotropy and elastic constant decreased, and dielectric anisotropy increased. From a calculation with MOPAC ver. 6.0, it is clear that elastic constants depend upon shapes of molecules under a restricted condition.

By blending the investigated compounds as main components, different nematic mixtures, having low threshold voltage low viscosity, large optical anisotropy or wide nematic range, which are suitable for specific applications for AM-LCD, were obtained
