Title: Spectral polarity index: a new method for determining the relative polarity of solvents [1]
Abstract: The relative polarity of a number of solvents, including perfluorocarbons, has been determined by measuring the bathochromic shift (as the solvent polarity increases) of the UV-visible λmax of a new class of dyes, the (α-perfluoroheptyl-β,β-dicyanovinyl)aminostyrenes [2]. This new measure of polarity, which is defined as the Spectral Polarity Index, Ps, appears to be particularly useful in characterizing nonpolar solvents such as perfluorocarbons.
