摘要：

A new fluorescent probe for the detection of Hg2+ was designed and synthesized via attaching N-methylisatin to rhodamine B hydrazide through an imine linkage. In an ethanol-Tris buffer medium, the addition of Hg2+ caused a strong orange fluorescence and a visual color change from colorless to pink. Other coexisting metal ions did not interfere with the detection of Hg2+. The research on the detection of Hg2+ in natural water suggested the possibility of practical applications in environment monitoring. Based on ESI-MS analysis, the He -sensing mechanism was proposed.
