Use of the SPP scale for the analysis of molecular systems with dual emissions resulting from the solvent polarity.
The solvent polarity/polarizability (SPP) scale is shown to be highly useful for analyzing the solvatochromic behavior of molecular systems emitting dual fluorescence by virtue of the solvent polarity. Stokes' shift data are presented on a test set of seven solutes in 58 solvents correlating with the SPP (single parameter polarity/polarizability index). SPP values for seven further solvents are given, extending the previously available list.
