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...
In this research, the chiral dopant molecules derived from tartaric acid was utilized for enlarging HTPs in nematic phases and widening blue phase temperature ranges. As a result, we clarified that the HTPs were affected by the interaction of the ...
We have been studying electro-responsive columnar liquid crystalline ureas. In this study, we attempted to synthesize novel ferroelectric columnar liquid crystals. To stabilize ferroelectricity acetyl groups were introduced at the terminal alkylch...
We recently synthesized a chiral dopant DA (Scheme1), with two rod-like units and a rigid arched unit. It is predicted that DA thermally decomposes and to recombines through retro-Diels-Alder and Diels-Alder reaction of anthracene and fumaryl este...
