Paper Abstract

The birefringence of some different monomesogen and bimesogen liquid crystals has been determined. Birefringence is an important liquid crystal property in the context of display and optical communication applications. Members of the well known homologous series of liquid crystals nOCB were measured for comparison with a series of cyanobiphenyl bimesogens containing a novel fluorinated mesogenic group and novel conjugated ring structures. Comparative measurements were made by a rotating analyser technique, using a Helium-Neon laser as an illumination source. We present the birefringence and phase characterisation for several different liquid crystal materials, inferring structure-property relations and the effect of forming a bimesogen.
