Properties of liquid crystalline compounds, which have a strong intermolecular interaction originated from synparallel arrangement of the two mesogenic cores, were investigated by polarized light optical microscopy and DSC, and the layer distances were measured by powder X-ray diffraction. Compounds 1b〜1i exhibited smectic A phases in which pural inconstant layer distances (non-interdigitated and interdigitated states) were observed.
