Right- and left-handed homochiral domains segregate in a fluid smectic phase of the racemic (R*,S*)-beta-Me-TFMHPOBC analogue shown. This CF(3)-containing liquid crystalline compound exhibits an electrooptic response in a homogeneous cell, although no macroscopic dipole is expected to exist. Moreover, the homeotropic cells of this material exhibit striped domains, which are associated with fine stripes having two opposite tilt senses with respect to the predominant stripes.

Photoinduced diastereoselective addition of perfluoroalkyl iodides in the presence of an aqueous solution of Na2S2O3 was an excellent method for iodoperfluoroalkylation of acrylic acid derivatives bearing a chiral auxiliary, with moderate to good stereoselectivities and with no detectable side products. The iodoperfluoroalkylation of N-acyloylcamphorsultam provided a convenient route for preparing chiral fluorine-containing amino acids.
