Journal ArticleDOI
Nature of the chemical bond formed with the structural metal ion at the A9/G10.1 motif derived from hammerhead ribozymes.

TL;DR: It is concluded that Cd(II) can form an inner-sphere complex with the nucleobase in the motif, and large 1H and 31P chemical shift perturbations for the motif are observed, which suggests that the metal ion at these motifs is not a catalytic center of hammerhead ribozymes.
Journal ArticleDOI
Solvation for Ions and Counterions: Complementary Relation between Ion−Counterion and Ion−Solvent Interaction
TL;DR: The microscopic environments around a cation and its counterion were experimentally studied for methanol solutions of CsCl, LiCl and LiClO4 through mass spectrometric analysis of clusters as discussed by the authors.
Journal ArticleDOI
Solvation-controlled clustering of a phenol–pyridine acid–base pair
Akihiro Wakisaka,Yoshitaka Yamamoto,Yoshikatsu Akiyama,Harutoshi Takeo,Fujio Mizukami,Kengo Sakaguchi +5 more
TL;DR: In this paper, it was shown that the observed clusters are controlled by the solvation structure depending on the solvent alkyl-chain length, and that the phenol molecules also formed clusters in methanol and acetonitrile, but not in propan-1-ol or propiontrile.
Journal ArticleDOI
Self-Association of m-Cresol in Aqueous Organic Solvents: Relation to Enzymatic Polymerization Reaction
Takahisa Oguchi,Akihiro Wakisaka,Shin-ichiro Tawaki,Hiroyuki Tonami,Hiroshi Uyama,Shiro Kobayashi +5 more
TL;DR: In this paper, the self-association of m-cresol in aqueous organic solvents (1,4-dioxane-water and methanol-water), which is an attractive pathway for synthesis of a new class of polyphenols withoutuse of toxic formaldehyde, was remarkably influenced by the water content.
Journal ArticleDOI
Central metal ion exchange in a coordination polymer based on lanthanide ions and di(2-ethylhexyl)phosphoric acid: exchange rate and tunable affinity.
TL;DR: Kinetic and selectivity studies suggest that a polymeric network of [Ln(dehp)3] has different characteristics than the corresponding monomeric complex, and such unique affinity can be explained by two factors: the coordination preference and steric strain caused by the polymeric structure.
