Anions as Dynamic Probes for Ionic Liquid Mixtures was written by Di Pietro, Maria Enrica;Castiglione, Franca;Mele, Andrea. And the article was included in Journal of Physical Chemistry B in 2020.Reference of 404001-48-5 This article mentions the following:
Ionic liquid (IL) mixtures were proposed as a viable alternative to rationally fine-tune the physicochem. properties of ILs for a variety of applications. The understanding of the effects of mixing ILs on the properties of the mixtures is however only in the early stages. Two series of ionic liquid mixtures, based on the 1-ethyl-3-methylimidazolium and 1-dodecyl-3-methylimidazolium cations, and having a common anion (tetrafluoroborate or bis(trifluoromethylsulfonyl)imide), were prepared and deeply characterized via multiple NMR techniques. Diffusion and relaxation methods combined with 2D ion-ion correlation (nuclear Overhauser enhancement) experiments were used for a better understanding of the interplay between dynamics and structure of IL mixtures A crucial role of the anion in driving the mixture’s behavior emerged, making them important “dynamic probes” for gaining information of the polar and nonpolar regions of ionic liquids and their mixtures In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Reference of 404001-48-5).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Imidazole derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. Many drugs contain an imidazole ring, such as certain antifungal drugs, the nitroimidazole series of antibiotics, and the sedative midazolam.Reference of 404001-48-5
