Imidazolium-based ionic liquids formed with dicyanamide anion: influence of cationic structure on ionic conductivity

Article Abstract:

The synthesis and characterization of ionic liquids of dicyanamide anion and various imidazolium-based cations is reported. The studies provide insight into various properties of ionic liquids such as thermal behaviors, hydrogen-bond donor (HBD) ability, polarity, viscosity, ionic conductivity, ion association, and surface tension.

High-pressure Raman studies on aqueous protonated thiazole: Presence of charge-enhanced C-H...O hydrogen bonds

Article Abstract:

Close interactions of the charge-enhanced C-H...O type is analyzed both experimentally and computationally in the protonated thiazole-water system. The formation of weak hydrogen bond is directly evidenced by a low-frequency shift of the hydrogen-bonded aromatic C-H stretch in the protonated thiazole moiety.
