With the increasing S2- ions from 0.1-45 μM, the ratio of fluorescence intensity at 545 nm to 440 nm (F545/F44 is linear to S2- concentration, and the detection limit of S2- was calculated to be 0.073 μM. Contrast to those fluorescence probes with single wavelength emission, Coumarin@GDP-Tb displays a comparable sensitivity, the introduced self-adjust wavelength improved the detection accuracy efficiently. The above 98.1 % recovery rates of S2- ions in the actual water sample demonstrated the practicability of Coumarin@GDP-T
