Abstract
A novel ratiometric and reversible fluorescence probe was designed and synthesized. The fluorescent probe recognizes Al<sup>3+</sup> to cause a blue shift in the fluorescence emission spectrum. Fluorescence probe can be used as a sensor to detect Al<sup>3+</sup> in living cells and Zebra fishes. The probe can detect the pH value when the alkalinity range was 8–10.
