Surfaces of 11 equimolar mixtures of ionic liquids (ILs) consisting of 1-alkyl-3-methylimidazolium cations (from [C2C1Im] to [C12C1Im]) with anions (Cl, [BF4], [TfO], [PF6], [Tf2N]) were observed using high-resolution Rutherford backscattering spectroscopy (HRBS). The elemental depth profiles of these IL mixtures were derived from the observed HRBS spectra through spectrum modeling. By comparing the observed depth profiles with those of pure ILs, the surface mole fractions of constituent ILs were estimated We found a general tendency that larger IL is enriched at the surface. The observed surface enrichment can be reasonably well reproduced by a simple thermodn. calculation based on the Sprow-Prausnitz equation. A slight deviation from the calculated result was ascribed to the nonideal behavior of the IL mixtures, which was neglected in the calculation In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Synthetic Route of C18H31F6N3O4S2).
3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Many natural products, especially alkaloids, contain the imidazole ring. These imidazoles share the 1,3-C3N2 ring but feature varied substituents. Imidazole derivatives have antibacterial, antifungal and anticancer functionality. It interacts with DNA and also binds to protein and stops cell division.Synthetic Route of C18H31F6N3O4S2
