Solute–solvent and solvent–solvent interactions in binary solvent mixtures. Part 1. A comparison of several preferential solvation models for describing E_T(30) polarity of bipolar hydrogen bond acceptor-cosolvent mixtures

Solvatochromic Study on Binary Solvent Mixtures with Ionic Liquids

“…One possible model for the preferential solvation based on the two-step solvent-exchange equilibrium is that proposed by Skwierczynski and Connors [16] and further extended and generalized by Roses et al [17]. Despite of electrolyte solutions it was expected that mixtures of organic solvents with room temperature molten salts can be treated analogously as a normal binary solvent mixture, and the non-linear behaviour results from the preferential solvation of the dye by one component of the mixture or other interactions between the components of this mixture (indicator + organic solvent + ionic liquid).…”

Solvents Design on the Basis of Molecular-Microscopic Properties of Binary Mixtures for Lycopene Extraction

“…Tables 1-3 Tables 1-3. Inverse to Sp, the solvatochromic parameters do not show a linear correlation with the volume fraction of constituents in the mixture, so they must be measured. All these parameters have been derived from previous studies [17][18][19] that are listed in Tables 1-3.…”

Solvatochromic And Fluorescence Spectroscopic Studies On Polarity Of Ionic Liquid And Ionic Liquid-Based Binary Systems

“…Band I corresponds to an S 1 (v=0) to S 0 (v=0) transition, while band III is an S 1 (v=0) to S 0 (v=1) transition. 16 The I I /I III emission intensity ratio of pyrene has been used to define polarity and an increase in the I I /I III indicates an increase in the solvent polarity. The I I /I III did not change appreciably with change in solvent.…”
