摘要：A simple 7-hydroxycoumarin-basecl compound L1 was rationally designed and synthesized behaving as a highly selective fluorescent sensor for Hg2+ in aqueous media. It shows selective and "turn-on" fluorescence upon addition of Hg2+. Fluorescence titration and H-1 NMR investigation reveal that the fluorescence enhancement of L1 upon Hg2+ addition is promoted by Hg2+-induced cyclization of L1 to a more rigid dihydrobenzofuran derivative.
