A novel rhodamine B derivative L was synthesized facilely by the condensation reaction of rhodamine B hydrazide and 2-hydroxyquinoline-3-carbaldehyde, and its structure was characterized by 1H NMR, MS techniques and elemental analysis. The recognition properties of the target compound L with metal ions had been investigated in CH3CN-H2O (VV=1∶1) solution by the ultraviolet spectrophotometry and the fluorescence spectrophotometry. The results showed that the probe L exhibited the selective colorimetric recognition of Cu2+ and the fluorogenic recognition of Hg2+. Upon the addition of Cu2+ or Hg2+, the spirolactam ring of probe L was opened and 1∶1 ligand-copper complex or 1∶2 ligand-mercury complex was formed, and both of the Cu2+ and Hg2+ recognition processes were proven to be a revisible process.

Key words: rhodamine B derivative, colorimetric recognition, fluorogenic recognition, metal ion
