Ferroelectric columnar liquid crystals have received much attention as energy-saving electronic materials. In this study, an N,N'-bis(3,4,5-tris((2-ethylhexyl)oxy)phenyl)urea was synthesized and characterized. As a result, the compound exhibited a ferroelectric columnar liquid crystal phase at low-temperature (63-103 degrees C), and succeeded in significantly lowering the temperature compared to conventional ferroelectric urea compounds (>105 degrees C). This is the first example where ferroelectricity is greatly affected by the temperature in a columnar liquid crystal phase.
