Highly sensitive fluorescent chemosensor for hypochlorite anion based on a novel irreversible ring-opening strategy

摘要

A novel strategy to design a fluorescent chemosensor for OCl~- which can be used over a pH span of 6-11 by Integrating the reactive phenylhydrazo group within rhodamine 6G has been achieved. Upon the reaction with OCl~-, a significant fluorescence enhancement was triggered with a detection limit down to the 10~(9) M range.
