AI Article Synopsis
Article Abstract
Ionic liquids (ILs), defined as low-melting organic salts, are a novel class of compounds with unique properties and a combinatorially great chemical diversity. Ionic liquids are utilized as synthesis and dispersion media for nanoparticles as well as for surface functionalization. Ionic liquid and nanoparticle hybrid systems are governed by a combined effect of several intermolecular interactions between their constituents. For each interaction, including van der Waals, electrostatic, structural, solvophobic, steric, and hydrogen bonding, the characterization and quantitative calculation methods together with factors affecting these interactions are reviewed here. Various self-organized structures based on nanoparticles in ionic liquids are generated as a result of a balance of these intermolecular interactions. These structures, including colloidal glasses and gels, lyotropic liquid crystals, nanoparticle-stabilized ionic liquid-containing emulsions, ionic liquid surface-functionalized nanoparticles, and nanoscale ionic materials, possess properties of both ionic liquids and nanoparticles, which render them useful as novel materials especially in electrochemical and catalysis applications. This review of the interactions within nanoparticle dispersions in ionic liquids and of the structure of nanoparticle and ionic liquid hybrids provides guidance on the rational design of novel ionic liquid-based materials, enabling applications in broad areas.

In this work, we carry out a systematic computer simulation investigation of the single particle dynamics at the free surface of imidazolium-based room temperature ionic liquids by applying intrinsic surface analysis. Besides assessing the effect of the potential model and temperature, we focus in particular on the effect of changing the anion type, and, hence, their shape and size. Further, we also address the role of the length of the cation alkyl chains, known to protrude into the vapor phase, on the surface dynamics of the ions.

Beryllium carbonate has the highest capacity to bind and release the greenhouse gas CO compared to amines, ionic liquids, CaCO or LiCO. The thermodynamic equilibrium for CO and BeO from BeCO is calculated. TGA of BeCO is used to determine the stepwise mechanism of its CO release, and the low melting point Li/Sr/BeCO is demonstrated.

In recent years, the integration of multifunctional properties into electrospun fabrics has garnered significant attention for applications in wearable devices and smart textiles. A major challenge lies in achieving a balance among intermolecular interactions, structural stability, and responsiveness to external stimuli. In this study, we address this challenge by developing intrinsically healable and photoresponsive electrospun fabrics composed of poly(vinylidene fluoride--hexafluoropropylene) (PVDF-HFP), thermoplastic polyurethane (TPU), and an azobenzene-based ionic liquid ([AzoCMIM][TFSI]).

Glyme-based electrolyte solutions provide new concepts for developing suitable lithium-ion batteries. The so-called solvate ionic liquids (SILs) are promising electrolytes. They are most efficient in equimolar mixtures of lithium bis(trifluoromethanesulfonyl)imide ([Li][NTf2]) and glyme, wherein the [Li]+ cation is supposedly fully solvated by glyme molecules.

Developing new organic radical emission systems and regulating their luminescence properties presents a significant challenge. Herein, we build dynamic and multi-emission band radical luminescence systems by co-assembling inorganic metal salts with carbonyl compounds in ionic liquids. After the assembling, dual-band, and excitation wavelength-dependent emission was observed upon light irradiation, one emission band originates from carbonyl radical after light irradiation, the other band from the ligand-metal charge transfer (LMCT) state, which benefits from the charge transfer from the radicals to the metal salts.
