摘要：
H2S is a reactive nucleophilic species with toxic effects towards human beings. Its efficient detection and marking is still a challenging job due to its similar nucleophilic character to a number of biothiols, like glutathione, cysteine, homocysteine etc. We report herein the first ever use of a chemosensor incorporating three electrophilic centres to achieve high sensitivity and very fast response time (40 s) towards H2S.
