A fluorescent probe decorated with an alkynyl ester unit ( e.g. propiolate) displayed a selective turn-on type fluorescent response towards cysteine. Following a sequential addition-cyclisation pathway mediated by the addition of cysteine, the pre-fluorescent dye rapidly transformed into a new struc...

Description
Summary:A fluorescent probe decorated with an alkynyl ester unit ( e.g. propiolate) displayed a selective turn-on type fluorescent response towards cysteine. Following a sequential addition-cyclisation pathway mediated by the addition of cysteine, the pre-fluorescent dye rapidly transformed into a new structure and induced a fluorescent response clearly observable with the naked eye. A fluorescent probe decorated with an alkynyl ester unit ( e.g. propiolate) displayed a selective turn-on type fluorescent response towards cysteine.
