摘　　要：A novel quinazolinone derivative ethyl 2-(2-methyl-4-oxo-1,2,3,4-tetrahydroquinazolin-2-yl)ace-tate(EMOTA)was synthesized and characterized by HRMS,^(1)H NMR,^(13)C NMR spectroscopy and X-ray crystal-lography,and the ion recognition performance of the compound was studied by fluorescence analysis measure-ments.The results showed that probe EMOTA has a rapid fluorescence response,good selectivity and sensitivity to Fe^(3+).When the concentration of Fe^(3+)was in the range of 0~10.0×10^(-5)mol/L,the fluorescence quenching could be affected by the probe,and the detection limit was 1.65×10^(-6)mol/L.In addition,the identification and detection of Fe^(3+)in water samples were studied,and the results showed that probe EMOTA has high efficiency,significant sen-sitivity and high selectivity on the recognition and detection of Fe^(3+)in water samples,which indicates probe EMOTA has a practical application prospect.
