Abstract
In amphiphilic liquid crystal molecules with hydroxyl end group, it has been reported that the molecules exhibit three types of the Smectic C phases. In these phases, monolayer (SmC) and bilayer (SmC', SmC") orderings were observed using the conventional X-ray diffraction (XRD). In this study, we investigated more detailed structures in the SmC' and SmC" phases using the high resolution small angle XRD. In summary, we found that the SmC" phase has a conventional bilayer structure and the SmC' phase has a frustrated bilayer structure.
