摘要：
A novel turn-off fluorescent probe containing a dansyl fluorophore has been synthesised. Its recognition properties towards various metal ions have been studied by fluorescence spectrometry. The compound showed a high sensitivity and selectivity to Hg2+ ion and a complexation ratio towards Hg2+ of 2 : 1. Its fluorescence intensity varied almost linearly versus the concentration of Hg2+ (0.8-8.4 mu mol L-1), and the detection limit of Hg2+ was estimated to be 0.88 mu mol L-1.
