9. Acetonitrile-water mixtures were used as eluents in HPLC analysis.
10. For example, cyclic voltammetry of 3c in acetonitrile solution shows in the range -2.0 to +2.0 V only one peak at 0.9 V vs SCE, due to the irreversible oxidation of the dansyl chromophore. This locates an hypothetical charge-transfer state at an energy above 2.9 eV, much higher than the energy (2.4 eV) of the excited state responsible for the emission.
11. The choice of this reaction medium was dictated by the solubility of 2c and 3c in the form of deprotonated sulfonamides.
