    • The facts that this deprotonation process accompanies no significant fluorescence intensity changes and that the disappearance of α-carbonyl protons in 1H NMR titration spectra suggest that the equilibrium between 1 and its ylide generated by the basic anions causes H/D exchange of α-carbonyl protons

    • Upon addition of cyanide to 1, the solution turns colorless then pale blue. The intensity of the blue color becomes more intense with time. This may imply that the acridinone 3 is responsible for the blue color.
