Fig. 6. Fluorescence intensity of 1 (10 μM) monitored at 462 nm in water/MeCN mixtures (99/1 v/v) at 25 °C with different pH, (red) with and (black) without OCl⁻ (50 equiv.). The mole fraction distributions of Cl₂, HClO, and OCl⁻ calculated based on the equilibria (eqn (1) and (2)) are shown by green lines.
