Summary: This Perspective highlights the pathways to prepare porous ionic liquids using easily accessible materials for reduced environmental impact. The study demonstrates that suspensions of porous solids are stable in eutectic mixtures, which indicates their potential in preparing porous ionic liquids. Porous ionic liquids maintain the wide electrochemical window observed in their precursor pure ionic liquids, making them suitable for green electrochemical reactions, especially those involving gases with enhanced solubility in the porous suspensions. Furthermore, their capacity as gas-rich media suggests potential sustainable biomedical and pharmaceutical applications, provided that non-toxic, biocompatible ionic liquids and porous solids are utilized.

Summary: In this study, we investigate the influence of ionic correlations on the reaction rates and selectivity of CO2 electroreduction. Through experiments, we find that at intermediate concentrations, the reduction rates of CO2 are accelerated and the efficiency of CO production is enhanced. The acceleration of CO2 reduction is due to the amplification of potential-dependent driving forces, rather than changes in onset potential. These findings are applicable to both cocatalytic and noncatalytic ions.

Summary: This study proposed the use of ionic liquids (ILs) for the selective separation of natural analogues artemisitene and artemisinin. The aqueous solution of N-allyl-N,N,N-trimethylammonium chloride ([AA][Cl]) exhibited excellent capability for this separation, with a separation selectivity of 12.23 under optimal conditions. π-π complexation between artemisitene and [AA][Cl] played a major role in the separation process, and counter-flow extraction showed advantages in energy consumption and product yield compared to multistage cross-flow extraction.

Summary: In this study, the interaction between ionic liquids (ILs) and graphene oxide (GO) was investigated using density functional theory. It was found that the adsorption of ILs on GO reduced the HOMO-LUMO energy gap, weakened hydrogen bonding interactions, and charge transfer played a key role in the adsorption process. Additionally, the forces at play depended on whether the ILs were on the hydroxyl side of GO or not, with van der Waals interactions being prominent.

Summary: Understanding the preparation and stabilization of silver nanoparticles in ionic liquids is still needed to investigate. Various groups have reported the synthesis and stabilization of silver nanoparticles (Ag NPs) in ionic liquids (ILs) on varying the cation and anion. The impact of alkyl chain in the cation and the interactions between the ILs and Ag NPs were investigated using imidazolium ring-based ionic liquids. DFT and TD-DFT calculations were performed to study the interactions and thermodynamic parameters.

Summary: Controlling charge density in low-dimensional materials using an electrostatic potential is a powerful tool to explore and manipulate their electronic and optical properties. Ionic liquid (IL) gating, which only requires a metallic electrode in contact with IL, provides an alternative method with excellent gating properties. However, many ILs are not suitable for optical experiments in the mid-IR region due to low optical transparency and degradation. In this study, we present two electrolytes based on bromide ILs dissolved in PMMA, which can achieve high charge densities and exhibit optical transparency, making them promising candidates for electronic and mid-IR optoelectronic devices.

Summary: Four divalent ionic liquids based on imidazolium cations with alkyl or ether functionalized side-chains were synthesized and characterized. These ionic liquids exhibit variable densities and viscosities, with non-additive molar volumes observed in the case of double-charged imidazolium cations, likely due to intramolecular hydrogen bonding. The carboxylate-based divalent ionic liquids show reversible carbon dioxide absorption behavior, with improved stoichiometry achieved in certain compositions, making them amongst the most effective for carbon dioxide absorption.
