A novel excited-state intramolecular proton transfer (ESIPT) dye with unique near-IR keto emission and its application in detection of hydrogen sulfide

A new ESIPT dye of benzothiazole with a conjugative electron acceptor was discovered and synthesized. Due to its unique NIR keto emission and a large Stokes shift, it was used to develop a fluorescent probe for sensitive and selective detection of hydrogen sulfide.
