The dual response of Hg^2＋ was not only in the marked color change of the solution from dark green to colorless, but also in the significant enhancement of the fluorescent intensity of the chemodosimeter in aqueous acetonitrile. Moreover, when the chemodosimeter was assembled into nanoparticles, it could also exhibit remarkably dual response of color change and fluorescence enhancement for detection of Hg^2＋.展开更多
