摘要： In this paper, 4-dimethylamino 2,5-dihydroxy chalcone (DMADHC), which exhibits excited state intramolecular charge transfer (ICT) characteristics, was synthesized and characterized. A sensitive optochemical sensor for Fe ~3 ion was developed using DMADHC as fluorescence receptor. The fluorescence of DMADHC was gradually quenched with the addition of Fe ~3 ion, which attributed to the formation of 1:1 complex between DMADHC and Fe~3 ion. The sensor exhibited excellent selectivity for Fe~3 ion over a large number of cation ions such as alkali, alkaline earth and transitional metal ions with a linear range of 3.984×10 ~(-7)1.135×10~(-5) and a limit of detection of 8.223×10~(-8) mol/L. On this basis, the sensor was preliminary applied to the determination of the content of iron ions in multi-vitamin tablet with satisfied results and the recoveries were in the 95100% interval, and precision (n=5) was better than 5%.
