Solvation properties of protic ionic liquids and molecular solvents

Abstract

Ionic liquids (ILs) are highly tailorable solvents with many potential applications. Knowledge about their solvation properties is highly beneficial in the utilization of ILs for specific tasks, though for many ILs this is currently unknown.

The physical significance of the Kamlet–Taftπ* parameter of ionic liquids

“…65 suitability for protic ILs. [66][67][68][69] Hydrogen-bonding also plays a role for Stokes shift relaxation of indoline derivatives. 41 Hence, we recommended the use of Th (see Fig.…”

The unseen evidence of Reduced Ionicity: The elephant in (the) room temperature ionic liquids

“…Protic Ionic Liquids (PILs) are a sub-class of the nowadays widely studied ionic liquids [1][2][3][4][5] since they follow the general definition given by Walden in 1914, i.e., "water-free salts that are in liquid form below 100 °C" [6]. A more rigorous definition is currently adopted as water-free organic salts showing a melting point at temperatures below their decomposition.…”

Electrolyte solvation chemistry for lithium–sulfur batteries with electrolyte-lean conditions

“…Another strategy takes the opposite route against sparingly solvating electrolyte, termed as highly solvating electrolyte, in which high donor number (DN) or high dielectric constant solvents are employed to solubilize LiPSs as much as possible (at least higher than the benchmark electrolyte) [97,101]. The donor number is based on the heat of reaction between the 'solvent' dissolved in 1,2dichloroethane (CH 2 ClCH 2 Cl) and antimony pentachloride (SbCl 5 ), reflecting the Lewis basicity of a solvent [102], while the dielectric constant indicates the electronic polarizability of a solvent [103,104]. The commonly used solvents with above two parameters are listed in Table 1 [97,105].…”
