ureidopyrimidine derivative, a potential electrochemical sensor for trifluoromethanesulfonic acid and trifluoroacetic acid, were investigated using UV/Vis, NMR, and CV measurements. Upon protonation, a structural change was found to take place leading to the formation of a proper binding site for the anion of the acid. Anion binding has been proved for both CF3SO3– and CF3CO2–as well as for the BF4– anion
