摘要：

Anti-ferroelectric (SmCA*) and ferroelectric (SmC*) phases of alpha-trifluoromethyl-beta-methyl-substituted liquid crystalline (LC) molecules, synthesized highly diastereo- and enantioselectively through our chiral titanium complex-catalyzed fluoral-ene reaction, were determined by thermal analysis and electro-optic measurements. Phase transitions were thus found to be critically dependent on the diastereomeric excess (diastereotropic) for ul (R(alpha)S(beta))-diastereomers of the LC molecules.
