Original Article


A highly sensitive fluorescent turn-on probe specific for mercury ion has been developed on the basis of mercury ion-promoted hydrolysis of a pyrene-1-carbaldehyde hydrazone (1). The chemical conversion of 1, catalyzed by Hg2+ ions, was studied by using UV, fluorescence and 1H NMR spectroscopy, which clearly showed the conversion of 1 to highly fluorescent compound 1-pyrenecarboxaldehyde (2).
