           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.
