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>Liquid crystalline urea derivatives indicate good electro-responsiveness, and their homeotropic and homogeneous alignments can be easily switched by application and removal of an external electric field. In this study, the columns of liquid cry...
<p>A diphenyl urea derivative rac-1 possessing six racemic citronellyl groups was synthesized. Compound rac-1 is not a single stereoisomer but a mixture of 21 stereoisomers. From measurements of POM, DSC and XRD measurements, it was found that rac...
<p>To realize ferroelectrically switchable biaxial smectic A phases, perfluoroarene-arene (PFA-A) interaction and a bent chain structure were introduced to rod-like molecules. In ferroelectric switching experiments, the molecules with a bent termi...
<p>Lanthanides have a high magnetic moment derived from 4f orbital electrons not involved in bonding. In this study, we focused on the orientationally order of the columnar liquid crystal phase to improve the magnetic properties by increasing the ...
