“…It is also interesting to compare the results obtained with the data on viscosity, η, of the systems investigated. The temperature dependencies of viscosity based on literature sources − are presented at Figure S1 in the Supporting Information. The mutual sequence of the D values for different ILs corresponds qualitatively to the data on their viscosity, namely, the minimum D values are observed for [bmim] Cl with the highest viscosity, and the maximum D ones are registered for ILs with lowest viscosity ([bmim] TFO and [bmim]BF 4 ).…”

As the development of the work (J. Phys. Chem. B 2019, 123 (10), 2362−2372), we have investigated the translational mobility in the same set of dried imidazoliumbased ionic liquids (ILs) [bmim]A (A = BF 4− , NO 3 − , TfO − , I − , Br − , and Cl − ) in a wide temperature range using the NMR technique. It is shown that for the [bmim] + cation, the temperature dependencies of product Dη do not follow the Stokes−Einstein relation for most systems studied, that is, the so-called "diffusion−viscosity decoupling" was realized. The correlation between local and translational mobility in pure IL of the [bmim][A] type was investigated using the data on NMR relaxation rates and diffusion coefficients. The most recent hypothesis of "water pockets" in mixtures of IL with water is critically discussed. Considering the totality of data in the literature and obtained here, we propose a specific model of the microstructure which may be applied up to water concentrations of 80−90 mol % (the structure of water-rich solutions is out of our current consideration). To confirm the model, molecular dynamics simulations of "IL−water" mixtures were also carried out.

“…It is well-known that a solvation process is not only influenced by the solute-solvent interactions but also by the interfacial tension of solute and solvent [11]. The alkyl chain length of an IL has a marked influence on its density, viscosity, surface tension, melting point, and thermal stability [12][13][14][15][16][17][18][19][20][21]. A better understanding of the behavior of an IL as a solvent and as a homogeneous catalysis demands the knowledge of surface tension and its temperature dependence.…”

“…There are also reports on the thermo‐physical properties of ILs with anions, such as, [BF 4 ] − 15, [PF 6 ] − 16, [Br] − 17, [Cl] − 18 and [EtSO 4 ] − 19, among others. For the same cation, 1‐ethyl‐3‐methylimidazolium [C 2 mim] + , it is shown a complete database on the thermophysical properties of ionic liquids with different anions, including density, viscosity, refractive index, isobaric thermal expansivity and heat capacity of eight ionic liquids, allowing therefore the design of related industrial processes.…”

Effect of Ionic Liquid Anion Type in the Performance of Solid Polymer Electrolytes Based on Poly(Vinylidene fluoride‐trifluoroethylene)

The effect of different anions within the ionic liquid in the characteristics of solid polymer electrolytes (SPEs) based on P(VDF‐TrFE) has been investigated. 1‐ethyl‐3‐methylimidazolium acetate, [C2mim][OAc], 1‐ethyl‐3‐methylimidazolium triflate, [C2mim][(CF3SO3)], 1‐ethyl‐3‐methylimidazolium lactate, [C2mim][Lactate], 1‐ethyl‐3‐methylimidazolium thiocyanate, [C2mim][SNC] and 1‐ethyl‐3‐methylimidazolium hydrogen sulfate [C2mim][HSO4] have been used in SPE prepared by solvent casting. The polymer phase, thermal and electrochemical properties of the SPE have been determined. The thermal and electrical properties of the SPEs strongly depend on the selected IL, as determined by their different interactions with the polymer matrix. The room temperature ionic conductivity increases in the following way for the different anions: [SNC]>[CF3SO3)]>[HSO4]>[Lactate]>[OAc], which is mainly dependent on the viscosity of the ionic liquid.
