Vibration Modes at Terahertz and Infrared Frequencies of Ionic Liquids Consisting of an Imidazolium Cation and a Halogen Anion
The terahertz and infrared frequency vibration modes of room-temperature ionic liquids with imidazolium cations and halogen anions were extensively investigated. There is an intermolecular vibrational mode between the imidazolium ring of an imidazolium cation, a halogen atomic anion with a large absorption coefficient and a broad bandwidth in the low THz frequency region (13-130 cm-1), the intr...
متن کاملCrystal structure of dimethylformamidium bis(trifluoromethanesulfonyl)amide: an ionic liquid
At 100 K, the title mol-ecular salt, C3H8NO+·C2F6NO4S2-, has ortho-rhom-bic (P212121) symmetry; the amino H atom of bis-(tri-fluoro-methane-sulfon-yl)amine (HNTf2) was transferred to the basic O atom of di-methyl-formamide (DMF) when the ionic liquid components were mixed. The structure displays an O-H⋯N hydrogen bond, which links the cation to the anion, which is reinforced by a non-convention...
متن کاملSynthesis of an ionic liquid with an iron coordination cation.
An iron-based ionic liquid, Fe((OHCH(2)CH(2))(2)NH)(6)(CF(3)SO(3))(3), is synthesized in a single-step complexation reaction. Infrared and Raman data suggest NH(CH(2)CH(2)OH)(2) primarily coordinates to Fe(iii) through alcohol groups. The compound has T(g) and T(d) values of -64 degrees C and 260 degrees C, respectively. Cyclic voltammetry reveals quasi-reversible Fe(iii)/Fe(ii) reduction waves.
متن کاملCation identity dependence of crown ether photonic crystal Pb2+ sensing.
We quantitatively modeled the volume phase transition of a hydrogel containing a crystalline colloidal array with a crown ether ligand which binds Pb2+. The hydrogel volume response and the wavelength diffracted depend on the Pb2+ concentration and on both the ionic strength and the valence of the nonbinding ionic species. We successfully modeled the response of this hydrogel Pb2+ sensor to ion...
متن کاملExplaining Ionic Liquid Water Solubility in Terms of Cation and Anion Hydrophobicity
The water solubility of salts is ordinarily dictated by lattice energy and ion solvation. However, in the case of low melting salts also known as ionic liquids, lattice energy is immaterial and differences in hydrophobicity largely account for differences in their water solubility. In this contribution, the activity coefficients of ionic liquids in water are split into cation and anion contribu...
