Using the novel-model liquid crystals (LC) having two stereogenic centers in the molecule (CF3 and CH3), which were synthesized by the chiral titanium complex-catalyzed carbonyl-ene reaction with fluoral, the relationship between the appearance of antiferroelectricity and conformational arrangement were examined, From the results of our investigation, we concluded that the relative stereochemistry of the diastereomeric chiral portion should give strong effect on the preference and the thermotropic stability of SmCA* phase.
