Abstract

Anti-ferroelectric (SmCA*) and ferroelectric (SmC*) phases of α-trifluoromethyl-β-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 (RαSβ)-diastereomers of the LC molecules.
