“…After addition of GBL, the decrease in the viscosity of the mixture may be due to the high relative permittivity of GBL, which causes an increase in ion solvation, weakening of the ion–ion interactions, and result in a decrease in the viscosity of the mixture. A similar type of behavior for viscosity is observed in earlier reports. − ,− With increasing the temperature (25–35 °C), the value of viscosity decreases. Further, there is a decrease in the density for [bmim][BF 4 ] observed on addition of GBL (Figure and Table S2).…”

“…The same group also reported the effect of alkyl chain length of the IL and temperature on H-bonding interactions within the mixture of IL + GBL . Further, they also reported the effect of substitution of the methyl group at the C-2 position and alkyl side chain length of the 1,2,3-trialkylimidazolium IL on H-bonding interactions in IL + GBL mixtures . Vraneš et al also reported the H-bonding interactions in the mixture of GBL with 1,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide ([mmim][Tf 2 N]) binary mixtures .…”

“…It is well documented that the C-2 proton of the [bmim + ] cation of IL, takes part in hydrogen bonding, and the HBA character of GBL can be clearly reflected by its HBA basicity, β ≈ 0.46 (Table ). So, there may be a possibility of the interaction of the C-2 proton of the [bmim + ] cation of IL with the oxygen of GBL. − In earlier reports, Gadžurić et al clearly demonstrated the H-bonding interaction between the cation of IL with the carbonyl oxygen of GBL by thermodynamic studies . The same group also reported the effect of alkyl chain length of the IL and temperature on H-bonding interactions within the mixture of IL + GBL .…”

The co-solvent modified ionic liquid (IL) systems offer favorable physicochemical properties, which render them as suitable solvents for several technological applications. Therefore, it is an utmost need to achieve a full understanding of such systems before their further applications. Here, solvation properties of 1-butyl-3-methylimidazolium tetrafluoroborate, [bmim][BF4], and γ-butyrolactone (GBL) mixture, which is an important binary mixture for several electrochemical applications, are explored by multiprobe spectroscopic and theoretical studies. The Reichardt polarity parameter (E T N) and Kamlet–Taft parameter (α, β, and π*) are determined with several absorbance probes. The unusual synergism in the probe’s response is observed within the [bmim][BF4] and γ-butyrolactone (GBL) mixture. Such type of anomalous behavior is also observed in the response of the following fluorescence probes: 8-anilino-1-naphthalene sulfonate (ANS), 6-propionyl-2-(dimethylamino)naphthalene (PRODAN), and pyrene (Py). This unusual behavior is explained by considering the role of solvent–solvent interactions between IL and GBL molecule in the cybotactic region of probes. The occurrence of solvent–solvent interaction and other possible interactions within the binary system are also explored by Fourier transform infrared, dynamic viscosity, and density studies. Further, the preferential solvation model and density functional theory also provide the useful evidence of solvent–solvent interactions within the binary mixture.

“…Whereas understanding the properties of pure ILs is of fundamental interest, the practical applications generally require the admixture of other compounds, acting either as a reactant or product or as a cosolvent required for process optimization. 10 Some earlier investigations [11][12][13][14] reveal that addition of an IL in an organic solvent enhances the electrochemical and thermal stability of IL/organic solvent binary mixtures which often reflects in higher electrical conductivity and better device performances at low temperature than comparable mixtures of salts with high melting point temperatures. 15 Recently, it has been demonstrated that ILs can serve as an excellent model system for investigating the influence of the ion structure on the mobility and ion pairing even in aqueous solutions, where the interionic interac-tions are weak.…”

“…Pure ILs are usually quite viscous and less conductive, whereas the mixing of ILs with molecular liquids (cosolvents) causes a significant decrease of viscosity and a sharp increase of conductivity. [11][12][13][14] A huge number of investigations on conductivity of mixtures of ILs with molecular solvents is available in the literature. Surprisingly, despite the large practical interest for such systems, systematic studies of the transport properties of binary mixtures of ILs and cosolvents in a broad concentration range -from diluted solutions to pure ILs -are still scarce.…”

Ionic liquids belong to the most investigated systems in the recent years and this field is still significantly growing with an increased focus on developing ionic liquids for specific applications, along with fundamental research. In the present featured paper the similarity and differences between common, "classical" electrolytes and common surfactants and ionic liquids along with the surface-active ionic liquids are discussed in order to stress their significance and point out on their weak points. A short survey of the literature data reveals namely that ionic liquids in solutions behave like "classical" electrolytes and can be described by existing models in the range of their validity. There is still a lack of models describing well the concentrated electrolyte solutions and here ionic liquids, less limited by solubility as common electrolytes, can serve as model systems. The micellization of surface-active ionic liquids in aqueous solutions can be described in the same way as for common surfactants, but surface-active ionic liquids offer more possibilities to study specific ion and isomer effects. They are also quite promising systems to study the aggregation processes in non-aqueous solutions.
