Abstract

Null transmission ellipsometry and resonant x-ray diffraction are employed to study the effect of enantiomeric excess (EE) on the phase behavior of antiferroelectric liquid crystal 10OTBBB1M7. Phase sequence, layer spacing, and pitch of the helical structures of the smectic-Cα* and smectic-C^* phases are studied as a function of temperature and EE. Upon reducing EE, a liquid-gas-type critical point of the smectic-Cα* to smectic-C^* transition is observed, as well as the disappearance of the smectic-Cd4* and the smectic-Cd3* phases. Results are analyzed in a mean-field model.
