Anions are fundamental species in the environment and in living cells; therefore, the recognition of anions is important. We found that silanol derivatives, including silanediols, silanetriol, 1,3-disiloxane-1,3-diol, and 1,3-disiloxane-1,1,3,3-tetraol, form multiple hydrogen bonds with anions in organic solvents. The X-ray single crystal …

Biocompatible zwitterionic polymers may be useful as drug delivery systems for cancer therapy. However, the copolymerization of zwitterionic and hydrophobic monomers is difficult owing to their different solubilities. In the present study, we achieved the solid-state copolymerization of sulfobetaine methacrylate (SBMA) and …

Ditopic receptors with different terminal substituents on urea moieties linked with ether groups are prepared, and the solubilization of high‐concentration LiCl by the receptors in acetonitrile is evaluated. The unsymmetrical receptors have higher solubility than the corresponding symmetrical receptors, and the complex …

Abstract A concentrated lithium salt solution is widely used as an electrolyte of lithium-ion batteries. We have previously reported that simple and flexible ditopic receptors bearing anion and cation recognition sites forms LiCl complex resulting in the highly concentrated solution in acetonitrile. …

Copper-based conductive ink has received attention to fabricate thin, flexible, and lightweight devices through printing techniques. In particular, the copper formate based conductive inks, called metal organic decomposition (MOD) inks, which are fabricated by using amine ligand coordinated copper formate have been …

Lithium chloride (LiCl) is an inexpensive and environmentally friendly salt abundant in the ocean. However, the insolubility of LiCl in conventional electrolyte solvents prevents the practical use of LiCl for lithium-ion batteries. Here, we report a novel method to increase the solubility …

We investigated whether soticlestat (TAK-935), a newly discovered cholesterol 24-hydroxylase (CH24H) inhibitor now in phase 3 clinical trials for Dravet and Lennox-Gastaut syndromes, has effects on neurodegeneration in both chronic and acute animal models associated with glutamate hyperexcitation. Soticlestat was administered at …
