Abstract

One series of chiral fluorinated benzoates have been synthesized. These compounds were characterized by IR, ¹H NMR, ¹⁹F NMR, MS, and elemental analysis. Their phase transition behavior was investigated by DSC and polarizing optical microscopy. Generally, they show an enantiotropic SmA phase. The effect of lateral and terminal fluoro-substitution was studied in this series.
