Solvatochromic probes are often used to understand solvation environments at the molecular scale. In the case of ionic liquids constituted by an anion and a cation, which are designed and paired in order to obtain a low melting point and other desirable physicochemical properties, these two indivisible components can interact in a very different way with the probe. This is the case with one of the most common probes: Reichardt’s Dye. In the cases where the positive charge of the cation is delocalized on an aromatic ring such as imidazolium, the antibonding orbitals of the positively charged aromatic system are very similar in nature and energy to the LUMO of Reichardt’s Dye. This leads to an interesting, specific cation-probe interaction that can be used to elucidate the nature of the ionic liquids’ cations. Parallel computational and experimental investigations have been conducted to elucidate the nature of this interaction with respect to the molecular structure of the cation.

“…Ionic liquids (ILs) are a class of low melting organic salts, which have attracted a great amount of research interest in the past two decades [ 1 ]. Due to their peculiar physicochemical properties, including negligible vapor pressure, good thermal stability, high ionic and thermal conductivity, low flammability, wide electrochemical window, and unique solvent properties [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ], ILs have found broad use as catalysts and as unconventional solvents for synthesis [ 9 , 10 , 11 , 12 ], as well as for a wide variety of different applications, spanning from electrochemical applications [ 13 , 14 , 15 , 16 , 17 ], biomass processing [ 18 , 19 , 20 ], preparation of carbon materials [ 21 ], and CO 2 capture [ 22 ], to drug delivery and utilization as potential drug components [ 23 , 24 , 25 ].…”

Two couples of dicationic ionic liquids, featuring pyrrolidinium and piperidinium cations and different linker chains, were prepared and characterized. 1,1′-(propane-1,3-diyl)bis(1-methylpyrrolidinium) bromide, 1,1′-(octane-1,8-diyl)bis(1-methylpyrrolidinium) bromide, 1,1′-(propane-1,3-diyl)bis(1-methylpiperidinium) bromide, and 1,1′-(octane-1,8-diyl)bis(1-methylpiperidinium) bromide were synthesized in quantitative yields and high purity and thermally characterized through TGA and DSC analysis. In this study, we propose a preliminary comparative evaluation of the effect of the linker chain length and of the size of the aliphatic ammonium ring on the thermal and solubility properties of bromide dicationic ionic liquids.
