    • The pH values for Figure 1 were obtained via a pH meter. They therefore represent relative nominal pH readings (to display trends for the present study), not precise pH values.

    • Addition of 3 equiv of sucrose, glucose, or fructose to colored (preheated) 10% aqueous DMSO solutions containing 5.2 mM 1 affords characteristic color changes (purple, peach, and yellow for sucrose, glucose, and fructose, respectively, as described in ref 5) upon standing at it overnight. Interestingly, addition of preheated (6 min at gentle reflux) 10% aqueous DMSO solutions containing 3 equiv of each of the three sugars to colored (preheated) solutions of 1 also affords solution colors similar to those reported in ref 5, but within l min at room temperature. The absorbance intensity monitored at 538 nm diminishes corresponding to the previously observed order: sucrose (A = 0.546) > glucose (A = 0.493) > fructose (A = 0.174).
