On the Moisture Absorption Capability of Ionic Liquids.

Due to their many attractive physicochemical properties, ionic liquids (ILs) have received extensive attention with numerous applications proposed in various fields of science and technology. Despite this, the molecular origins of many of their properties, such as the moisture absorption capability, are still not well understood. For insight into this, we systematically synthesized 24 types of ILs by the combination of the dimethyl phosphate anion with various types of alkyl group-substituted cyclic cations─imidazolium, pyrazolium, 1,2,3-triazolium, and 1,2,4-triazolium cations─and performed a detailed analysis of the dehumidification properties of these ILs and their aqueous solutions.

Bis-Argentivorous Molecules Bridged by Phenyl and 4,4'-Biphenyl Groups: Structural and Dynamic Behavior of Silver Complexes.

Bis-argentivorous molecules ( and ), which have phenyl and 4,4'-biphenyl groups as linkers, have been prepared. The structures of Ag complexes with the new ligands ( and ) were investigated in solution and the solid state. The CSI-MS and H NMR titration of and with Ag show 1:1 and 1:2 complexes depending on the [Ag]:[] ratios.
