Replacement of stearyl groups with oleyl groups in a discoid molecule induced a rectangular columnar phase at low temperature. Although the molecule has no hydrogen bonding sites, the induced liquid crystal phase showed a highly efficient chiral a...

Holmium (Ho) is a lanthanide element with a high magnetic moment. Here, we create an amorphous metal-organic framework (MOF) that has no long-range periodic order but retains the basic components of MOF by using isophthalic acid as an organic link...
In the field of columnar liquid crystals, a new type of thermo-optical switching material that shows a birefringence inversion without changing the columnar alignment by controlling the temperature was synthesized. The urea molecules generate one-...
Electro-optically responsive liquid crystal (LC) nanocapsules were prepared by miniemulsion polymerization of oil-in-water emulsion monomer droplets dissolving LC compounds. As theoretically predicted based on the spreading coefficients, the choic...
An axially polar-ferroelectric columnar liquid crystal (AP-FCLC) phase that exhibits both switching and maintenance of the macro-polarity in the column axis direction has been achieved in an N,N'-bis(3,4,5-trialkoxyphenyl)urea compound (rac-1) pre...
<p>N,N'-bis(3,4,5-trialkyloxyphenyl)glutaramide and malonamide were synthesized and characterized. Both of the compounds exhibited a columnar liquid crystal phase in a wide temperature range including room temperature. In the second harmonic gener...
<p>Development of organic ferroelectrics in columnar liquid crystals (FCLCs) is desired for functional materials with flexibility and low environmental load. Though FCLCs have been achieved by adjusting the molecular shapes or the hydrogen bonds, ...
<p>In this study, we have aimed to achieve high-ordering and spontaneous chiral induction of columnar liquid crystal phases driven by the tight packing of peripheral bent tail-shaped chains. We synthesized a disk-shaped molecule surrounded by six ...
