“…[3c,68-70] The treating of solvatochromic effects of solvent mixtures will be also a challenge in terms of real physical constants. [71,72] Accurate density measurements as a function of solvent mixture composition along with the results of solvatochromism are required for this purpose. This conception works well for alcoholic solvents as shown already in two review articles.…”

Correlations of Reichardt's ET(30), the Catalán SdP (solvent dipolarity), SP (solvent polarizability), SA (solvent acidity), SB (solvent basicity), Kamlet‐Taft π* (dipolarity/polarizability), α (hydrogen bond donating ability) and β (hydrogen bond accepting ability) polarity parameters with the molar concentration of 161 pure organic solvents are presented. Mostly, linear relationships of the polarity parameter as a function of molar concentration are obtained as long as each individual solvent class is considered separately. A physically different interpretation of the ET(30), Kamlet‐Taft π* and α as well as Catalán SA and SB parameters has been proposed. Furthermore, the Hildebrand solubility parameter in combination with the diffraction index is used for the correlation analysis with the above‐mentioned solvent parameters. It can be concluded that empirical polarity parameters derived from solvatochromic UV/Vis measurements are inherently a function of the molecular structure of the probe.

“…The A°, a, b, and p are regression functionalities; A° refers to the intercept of the equation while a, b and p are coefficients that measures the magnitude of contribution of solvent acidity, basicity and polarizability respectively to the total solvation energy. The KAT parameters for the pure solvents and binary mixtures are obtainable from literature with the exception of aqueous propan-1-ol and propan-1-ol: propan-2-ol mixtures [14][15][16][17]. Regression for all possible combinations of the solvent parameters (α, β, π*) was carried out in the neat solvents (excluding carbon tetrachloride) and the binary mixtures; three cases including only one of the three parameters, another three cases involving two parameters only and a single case involving all three.…”

“…1). While the best practice for accurately obtaining , , and * is by using multiple solvatochromic probes per parameter, 29,30 there are limited datasets in the literature for cross comparison, and none known to the authors for PILs. Three solvatochromic probes were therefore selected in this work to determine , , and *: 4-nitroaniline (NA), N,N-diethyl-4-nitroaniline (DE), and 2,6-dichloro-4-(2,4,6-triphenylpyridinium-1-yl)phenolate (BD) ( Fig.…”

The ionic nature of a functionalized protic ionic liquid cannot be rationalized simply through the differences in aqueous proton dissociation constants between the acid precursor and the conjugate acid of the base precursor. The extent of proton transfer, i.e. the equilibrium ionicity, of a tertiary ammonium acetate protic ionic liquid can be significantly increased by introducing an hydroxyl functional group on the cation, compared to the alkyl or amino-functionalized analogues. This increase in apparent ionic nature correlates well with variations in solvent-solute and solvent-solvent interaction parameters, as well as with physicochemical properties such as viscosity.
