A novel rhodamine B derivative L1 was synthesized facilely by the condensation reaction of rhodamine B hydrazide and 3-aminopyridine, and its structure was characterized by 1H NMR, IR, HRMS-ESI and X-ray techniques. The recognition properties of the target compound L1 with metal ions had been investigated in water solution by the fluorescence spectrophotometry. The results showed that the probe L1 exhibited the selective colorimetric recognition to Fe3+than other metal ions. When the concentration of Fe3+ was in the range of 1×10-6~9×10-6 mol/L, there was a good linearity between the fluorescence intensity of the probe L1 and the concentration of Fe3+.
