A novel fluorescent pH sensor with tunable response range was designed based on highly fluorescent 3,4:9,10‐perylene tetracarboxylic ammonium, which could coordinate the paramagnetic Fe 3+ ions to turn off its fluorescence and could also release Fe 3+ to turn on the fluorescence again at higher pH. The fluorescent pH sensor was tunable in the presence of different ligands in aqueous solution. Copyright © 2011 John Wiley & Sons, Ltd.
