The Future

Ionic liquids, being composed entirely of ions, were once mainly of interest to electrochemists. Recently, however, it has become apparent that, inter alia, their lack of measurable vapor pressure characterizes them as green solvents, and that a wide range of chemical reactions (reviewed here) can be performed in them.

The Impact

Abstract The increasing interest in the development of new environment-friendly solvents has led to the synthesis of new materials that minimize the impact of solvents on the environment. However, most of the published studies on green solvents focus primarily on their physicochemical properties, with limited emphasis on their toxicological risk in the environment. In this study, the acute toxicities of five ionic liquids, 1-propylpyridinium tetrafluoroborate, 1-butylpyridinium tetrafluoroborate, 1-butyl-2-methylpyridinium tetrafluoroborate, 1-butyl-3-methylpyridinium tetrafluoroborate and 1-butyl-4-methylpyridinium tetrafluoroborate, on Vibrio fischeri and Daphnia magna are evaluated. In the latter bioassay, the presence and position of a methyl group on the pyridinium ring or the length of the chain attached to the nitrogen atom seem to be the key factors for toxicity. In the Vibrio fischeri study, the alkyl chain attached to the nitrogen atom has a considerable influence on EC50 values. Moreover, quantitative structure activity relationship studies are performed to relate their physicochemical properties with their acute toxicity.

Solvent Power

Understanding the miscibility behavior of ionic liquid (IL) / monomer, IL / polymer and IL / nanoparticle mixtures is critical for the use of ILs as green solvents in polymerization processes, and to rationalize recent observations concerning the superior solubility of some proteins in ILs when compared to standard solvents. In this work, the most relevant results obtained in terms of a three-component Flory-Huggins theory concerning the “Extra Solvent Power, ESP” of ILs when compared to traditional non-ionic solvents for monomeric solutes (case I), linear polymers (case II) and globular nanoparticles (case III) are presented. Moreover, useful ESP maps are drawn for the first time for IL mixtures corresponding to case I, II and III. Finally, a potential pathway to improve the miscibility of non-ionic polymers in ILs is also proposed.

: The unique properties of ionic liquids make them quite appealing for diverse applications, from “green” solvents (1st generation ionic liquids) to finely tuned materials (2nd generation ionic liquids). A decade ago, a 3rd generation of ionic liquids emerged which is focused on their prospective clinical applications, either as drugs per se or as adjuvants in drug formulations. In recent years, research focused on the use of ionic liquids for topical drug delivery has been increasing and holds great promise towards clinical application against skin cancers. This article highlights the growing relevance of ionic liquids in medicinal chemistry and pharmaceutical technology, which is opening new windows of opportunity.

: Green chemistry emphasizes designing novel routes to overcome health and environmental problems that occur during a chemical reaction. Green solvents are used in place of conventional solvents that are hazardous to both human and the environment. Solvents like water, ionic liquids, supercritical CO2, biosolvents, organic carbonates, and deep eutectic mixtures can be used as green solvents. The review focuses on the properties, applications, and limitations of these solvents.

A 19F solvatomagnetic comparison of 4-fluorophenol and 4-fluoroanisole yields a more reliable measurement of the hydrogen-bond acceptance of ionic liquids and green solvents than the solvatochromic comparison method.
