For achieving realization of ferroelectric columnar mesophase, we synthesized liquid crystalline urea-compounds. The compounds exhibited rectangular columnar and smectic A liquid crystal phases. We investigated their mesophases and structures by polarized optical microscopy (POM), differential scanning calorimetry (DSC), and one- and two-dimentional X-ray diffractions (XRD). In addition, we investigated their ferroelectric switching behaviors by applying a triangular wave voltage. As a result, all compounds showed a response to the electric field but did not show ferroelectric behavior.
