A facile naphthalene-based fluorescent chemodosimeter for mercury ions in aqueous solution

A facile naphthalene-based fluorescence turn-on chemodosimeter, 2-((2-(vinyloxy)naphthalen-1-yl) methylene)-malononitrile (MS1), for rapid, selective and sensitive detection of Hg2+ by mercury-promoted hydrolysis of the vinylether group has been reported. The probe displayed a fast response time, and a sensitive fluorescence response (100-fold fluorescence enhancement) to the detection of Hg2+ in aqueous solution.
