摘　　要：以7-羟基-4-甲基香豆素为原料制得两个香豆素衍生物(2a和2b);2与蔗糖反应合成了两个新型的香豆素单取代蔗糖衍生物(3a和3b),其结构经1H NMR,IR和LC-MS表征。3a和3b均具有较强的荧光强度,且荧光强度对pH的变化较为敏感,可选择性地识别Fe3+。Two coumarin derivatives（2a and 2b） were prepared from 7-hydroxy-4-methyl coumarin.Two novel mono-substituted sucrose coumarin derivatives（3a and 3b） were synthesized by the reaction of 2 with sucrose.The structures were characterized by 1H NMR,IR and LC-MS.The results showed that 3a and 3b exhibited strong fluorescence intensity which sensitively changed with pH and can selectively identify Fe3＋.
