Article Abstract
Deep eutectic solvents (DESs) represent a class of solvents that offer a number of advantages including minimal toxicity, affordability, low vapor pressure, and simple, environmentally friendly preparation methods. They have found utility in areas, such as gas absorption, metal plating, and extractions. However, the relationship between their solvation properties and chemical composition remains poorly understood. In this study, a broad range of Type I DESs composed of metal chlorides and an imidazolium salt were prepared, employed as gas chromatographic stationary phases, and characterized using the Abraham solvation parameter model by inverse gas chromatography. The Abraham solvation parameter model allows for the study of DES solvation properties and the effects of varying structural components on system constants using a linear-free energy relationship. The DESs were investigated by systematically varying their composition, including the type of metal chloride and the molar ratio between the metal chloride and the imidazolium salt. The results show that hydrogen bond acidity, hydrogen bond basicity, and dipolarity/polarizability interactions are strongly influenced by the type of metal chloride within the DES and the ratio of metal chloride to imidazolium salt in the eutectic mixture. Furthermore, a column pretreatment procedure is presented that enables the effective coating of highly polar DESs onto open tubular capillary gas chromatography columns.

Fluorescent N-heterocyclic carbene (NHC) metal complexes are useful for various chemical and biological applications. In this study, we developed a simple strategy to synthesize BODIPY-linked NHC metal complexes involving Ag, Cu, Ni, and Pd. The synthesis began with the preparation of BODIPY-imidazolium salt as a precursor ligand.

Application of photoactive transition metal complexes in lighting, imaging, sensing, and photocatalysis is usually based on the triplet metal-to-ligand charge transfer (MLCT) excited state of precious metal complexes with 4/5d valence electron configurations. These photocatalysts exhibit excited state lifetimes exceeding hundreds of nanoseconds. Simple 3d transition metal complexes containing abundant metals exhibit lifetimes below 1-2 nanoseconds, and they require multistep ligand syntheses mitigating large-scale implementation.

Aqueous pH-neutral organic redox flow batteries are emerging as viable solutions for sustainable grid-scale energy storage. However, their advancement is hindered by the limited availability of catholytes that maintain stable cyclability in both ambient air and inert environments, as well as challenges related to low-cost synthesis and achieving high volumetric capacity. Here, we present the design and synthesis of a series of imidazolium-decorated ferrocene derivatives, culminating in the identification of an ionic liquid-like catholyte that sustains cycling stability in air for over 2000 cycles.

Introduction: The discovery of alternative drugs has gained importance due to the many side effects of these drugs used for treatment.
Methods: Herein, the synthesis of a series of unsymmetrical imidazolium salts containing 4-acetylphenyl/4-formylphenyl and bioactive heterocyclic groups such as morpholine, piperidine, pyrrole or pyridine was reported. 4-(1--imidazol-1-yl)acetophenone and 4-(1--imidazol-1-yl)benzaldehyde were used as salt precursors.
