Efficient visualization of H2S via a fluorescent probe with three electrophilic centres. Issue 15 (31st March 2016) - Asthana, Sharad Kumar
Abstract : A meticulous design strategy of incorporating three electrophilic centres in an optical probe (FLA ) led to the achievement of high sensitivity and rapid response time (40 s) towards H2 S detection. Abstract : H2 S 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 H2 S.
