摘　　要：以香豆素为母体设计合成了一个新型荧光淬灭香豆素类衍生物探针，并研究了其识别能力和结合方式等。研究发现，该探针对Cu^2＋具有很高选择性、灵敏性，以及较高的荧光淬灭率（达95．2％）。并且当Cu^2＋浓度在3×10^-6～1．5×10^-5mol／L范围内，该探针的荧光强度和离子浓度具有较好的线性关系。A novel coumarin-based fluorescence quenching probe has been designed and synthesized. After studying its recognition capability and bonding mode, we discovered that the probe could high selectively and sensitively detect Cu^2＋ in solution as well as having a high fluorescence quenches rate which was up to 95.2% Additionally, there was a good linearity between the fluorescence intensity of the probe and the concentration of copper ion, when the concentration of Cu^2＋ was in the range of 3-15 μmol/L.
