Abstract

We synthesized the symmetrical achiral dimer, a,w-bis(4-(4'-butoxyphenyl)benzylthio)perfluoroalkane with different fluorocarbons on the center, and (4-(4'-butoxyphenyl)benzylthio)perfluoroalkyliodide. Their mesogenicity was studied by DSC and X-ray diffraction measurements, and POM observations. The relationship between the molecular shape and mesomorphic structure was determined and the dependence of fluoroalkyl chain length on the mesogenicity was studied.
