Synthesis and properties of liquid crystals with a perfluorinated linkage

Abstract

Several homologues of perfluorinated phenyl pyrimidine liquid crystals have been synthesized and their properties evaluated. The fluorination extent of the achiral terminal chain was found to affect both the phase diagram and the physical properties greatly. The mesomorphic properties of this novel liquid crystals are reported and the effect of the fluorination extent are discussed. Also, a novel liquid crystal with a perfluorinated linkage are synthesized and its properties are reported.
