Abstract
A novel turn-off fluorescent probe bearing a benzoxazole fluorophore has been synthesised and characterised. Its recognition properties towards different metal ions have been researched by spectrometry. The probe was highly selective and sensitive to Hg2+ and showed a complexation ratio towards Hg2+ of 1:1. Its fluorescence intensity varied almost linearly with the concentration of Hg2+ (1.6~8.6 μmol L−1), and the detection limit of Hg2+ was estimated to be 0.68 μmol L−1.
