摘要: For the rapid, ratiometric, fluorogenic and “naked eye” detection of H2S/S2−, a pro-excited state intramolecular proton transfer (ESIPT)-based receptor, 2-formyl-benzoic acid 2-benzothiazol-2-yl-phenyl ester (FBBP) has been designed. In presence H2S/S2− in preference to other common species, 2-(2-hydroxyphenyl)benzothiazole, well known ESIPT-containing agent, is recovered from FBBP. Thus, can be detected vitro vivo by such simple, easy-to-synthesise, practical ratiometric sensor.
