A visible light excitable colorimetric and fluorescent ESIPT probe for rapid and selective detection of hydrogen sulfide

In this paper, a visible light excitable ESIPT probe was developed, which was found to be a very promising colorimetric and fluorescent sensor for rapid and selective detection of hydrogen sulfide in aqueous solution. The sensing mechanism and the application of this probe for hydrogen sulfide detection in biological serum and in simulated wastewater samples were investigated.
