Bekarek has proposed that the solvatochromic parameters, π*, and α, and β, be modified to give πn*=π*/f (n2), αn=α/f (n2), βn=β/f (n2), where f (n2)=(n2– 1)/(2n2+ 1), and has suggested that, while the former parameter set is adequate to correlate some types of electronic spectral properties, the latter set is to be preferred for correlating most other ...

A New Method for the Characterisation of Solutes and Solvent Phases Using Solvatochromic Parameters
1991Abstract : The solvatochromic principle was first introduced by Kamlet and Tait in 1977 when a paper was published on the determination of the Beta1 scale for hydrogen bond basicity using the solvatochromic comparison method. Solvatochromic literally means solvent colour, and is derived from the effect the solvent has on the colour of an indicator used

Journal of Polymer Science Part B: Polymer Physics, 2015
The assembly of poly(3-hextylthiophene) (P3HT) in solvent mixtures is studied using solubility and solvatochromic parameters. Correlations between the excitonic coupling of P3HT assemblies and the Kamlet–Taft (α, β, π*) and ETN solvent scales reveal that lower excitonic coupling values are observed in binary mixtures characterized by low β values (0

Modeling solvent extraction using the solvatochromic parameters .alpha., .beta., and .pi.*
Analytical Chemistry, 1993A linear solvation energy relationship (LSER) employing only the solvatochromic parameters a, β, π * , and δ was shown to be adequate for describing solvent/water distribution processes for single solutes. Cavity formation is represented by the solvent αβ or αβ and π *2 .

Liquid Crystals, 2013
In application of liquid crystals (LCs) as solvents, it is required to obtain the polarity and solvatochromic polarity parameters such as the Kamlet–Abboud–Taft polarity functions. In this study, solvatochromic polarity parameters of some cyanobiphenyl nematic liquid crystals were acquired in different temperatures and phases, isotropic and anisotropic

Abstract The theoretical basis of empirical inverse linear relationships between the logarithms of the octan -1- ol water partition coefficient (KOW) and liquid or sub-cooled liquid aqueous solubility (SL(W)) is investigated in terms of fundamental solute-solvent interactions characterized by solvatochromic parameters.
