Summary

Basically, this contribution will summarize three key prior results in the FLC field: 1) antiferroelectrics composed of enantiomerically enriched molecules; 2) the Soto-Bustamante–Blinov antiferroelectric smectic bilayer composed of achiral molecules; and 3) the antiferroelectric phases composed of achiral bent-core molecules (bow-phases, or banana phases), which provide the first example of spontaneous chiral symmetry breaking in a liquid. The directed design, based upon these prior results, of a chiral ferroelectric banana (phase) composed of racemic molecules is then described. The latter provides an example of spontaneous polar symmetry breaking in a smectic liquid crystal.
