Probing Solvation in Ionic Liquids via the Electrochemistry of the DPPH Radical
The electrochemistry of the radical species 2,2-diphenyl-1-picrylhydrazyl, DPPH, has been studied in a range of common ionic liquids and its voltammetric response found to vary with the choice of anion. The trend observed is used to provide a relative Lewis basicity scale of nine ionic liquids commonly used as solvents.
