Abstract

The syntheses and mesomorphic properties of 4-alkylcyclohexyl- and 4-alkylcyclohexylethyl and 4-alkylbicyclo-hexyl-3-fluoro- and 3,5-difluorobiphenyl-4-isothiocyanates are described. The compounds are low melting, very broad range nematic liquid crystals and are very useful for the formulation of nematic mixtures of low viscosity and with a moderately high birefringence (0.3-0.35). The refractive indices, bulk viscosity and dielectric anisotropy extrapolated from Demus' ester mixture for the prepared compounds are presented. © 2010 Taylor & Francis.
