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...

<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, ...
