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...

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>Axially polarized ferroelectric columnar liquid crystals are expected to be a great candidate for ultra-high density memory device if the polar direction of each column can be controlled. Here, a diphenyl urea derivative possessing six racemic ...
<p>Columnar liquid crystals with ferroelectricity are expected to be applied to high-density memory devices by controlling the polarization direction of each column with a nanoscale diameter. Recently, we reported that a diphenylurea derivative ac...
<p>Although the construction of double-helix structures is an important challenge in supramolecular chemistry, no general construction method has been established for columnar liquid crystal phases. In this study, we have designed and synthesized ...
<p>In this study, we focus on a double helix structure known as a basic structure of DNAs in order tomaintain the induced polarization. The structure is important to protect a genetic information in DNA. Here,we synthesized Urea PE-(S)-Citronellyl...
<p>Ferroelectric columnar liquid crystals are materials in which the polar direction can be controlled by applying a voltage and can be maintained after removal of the voltage. In this study, we present an example of a perfectly bistable ferroelec...
