Five series of liquid crystals incorporating a 2,3,5,6-tetrafluorophenylene moiety and a terminal fluorosubstituted phenyl group have been prepared. The mesomorphic properties have been studied by polarizing microscopic textural observation and DSC measurements. The effect of terminal fluorosubstituent on mesomorphic behaviour has been discussed.
Synthesis and mesomorphic properties of some fluoro-substituted benzoates

Several series of fluoro-substituted benzoate liquid crystals have been synthesized. The results showed that the SmA phase is enhanced with the increasing of the degree of fluoro-substitution on the para- and meta-position of the terminal phenyl groups. And the molecules which have same molecular structural formula show nearly the same melting points. It is also discussed about the effect of the ester bond's direction on the mesomorphic properties.
