Here, an unprecedented phenomenon in which 7‐coordinate lanthanide metallomesogens, which align via hydrogen bonds mediated by coordinated H2O molecules, form micellar cubic mesophases at room temperature, creating body‐center...
The seven-coordinate Ho(III) aqua-tris(dibenzoylmethane)(DBM) complex, referred to as Ho-(DBM)3·H2O, was first reported in the late 1960s. It has a threefold symmetric structure, with Ho at the center of three dibenzoylmethane ligands and hydrogen...

Tetraalkoxylated diphenylureas U-3,4-Scit and U-3,4-raccit were synthesized from chiral and racemic citronellyl bromides as starting materials, respectively. To prepare pyroelectric crystals, these two compounds were slowly cooled from their molte...

In fabricating structural color materials with assembled colloidal particles, there is a trade-off between the internal stresses acting on the particles and the interactions between the particles during solvent volatilization. It is crucial to fab...
Axially polar-ferroelectric columnar liquid crystals (AP-FCLCs) consist of nanosized axially polarized columnar molecular aggregates arranged in parallel, in which their polar directions can be switched by applying an electric field and maintained...
<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 ...
