Reflection symmetry breaking in achiral rod-shaped smectic liquid crystals?

J Am Chem Soc. 2006 Apr 26;128(16):5318-9. doi: 10.1021/ja060478o.

Abstract

The SmC phase of 4'-octyloxyphenyl-4-octyloxybenzoate has been examined in light of recent reports that this phase is chiral. The results suggest that two varieties of chiral domains in LC cells of the phenylbenzoate are indeed formed, driven by interactions with surfaces. Application of sensitive probes for chirality and polarity in the absence of such interfacial influences failed to find any. Currently, there is no evidence that the subject SmC phase is chiral.
