A Low-temperature Axially Polar Ferroelectric Columnar Liquid Crystal Compound Possessing Branched Alkyl Chains

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-t...

Description
Summary: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 °C), and succeeded in significantly lowering the temperature compared to conventional ferroelectric urea compounds (>105 °C). This is the first example where ferroelectricity is greatly affected by the temperature in a columnar liquid crystal phase.
