A novel ionic liquid crystal oligomer, sodium 1,2-bis{6-[4-(4-cyanophenyl)phenyloxy]hexyloxycarbonyl}ethanesulfonate (SBCPHS), was prepared. Its physical properties were investigated by optical microscopy, differential scanning calorimetry and X-ray diffraction measurements. The compound exhibited two columnar phases, and the columnar-to-columnar phase transition did not accompany an enthalpy change. An optically isotropic phase was induced in a binary mixture with a nematic liquid crystal, 4-cyanophenyl 6-octyloxynapthalene 2-carboxylate. The mesophase formation of the ionic oligomer and its mixture are discussed in terms of microsegregation, excluded volume effect, and antiparallel interactions between cyanobiphenyl moieties.
