| Abstract: | A novel rhodamine B derivative 3 was synthesized facilely by condensation reaction of rhodamine B hydrazide and 2-chloroquinoline-3-carbaldehyde in this paper.And its structure was characterized by 1H NMR,MS spectra and elemental analysis.The recognition properties of target compound 3 with metal ions had been investigated in CH3CN-H2O solution by the fluorescence spectrophotometry.The results showed that the compound 3 as fluorescent probe exhibited selective recognition of Hg2+ and this recognition was inreversible. |
