A new one series of chiral schiff's base containing benzylidene aniline moieties was synthesized and characterized by IR, 1H NMR. elementary analysis, and polarized optical microscopy(POM). The yield of these synthetic compounds was in the range of 62~67℃. The results showed that most of the synthetic compounds were monotropic liquid crystal and exhibited chiral smectic C(Sc*) liquid crystal phases, and the range of phase transition temperature was to 71.4℃ from 45.0℃.
