In order to realize ferroelectric columnar mesophases, we synthesized LC urea-derivatives. The compounds exhibited hexagonal columnar and rectangular columnar LC phases. We investigated their phase transitions and superstructures 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, some compounds indicated high-speed ferroelectric switching and stability of the polarization.
