丹酰基团修饰的喹啉衍生物作为Cu2+和Hg2+荧光探针的研究

INVESTIGATION OF THE FLUORESCENCE PROBE FOR COPPER(Ⅱ) AND MERCURY(Ⅱ) BASED ON THE DANSYL AMINOQUINOLINE

    摘要
  • 摘要: 合成并表征了一种具有良好水溶性的荧光探针—8?(丹磺酰氨基)喹啉，它能够在水溶液中荧光识别和检测Cu2+和Hg2+.随着这2种离子浓度的增加，该探针的荧光发射强度均发生较大程度的猝灭，而相同测试条件下，其他9种所测试的常见重金属离子对该荧光探针的荧光发射性质几乎没有影响.因此，这是一种对Cu2+和Hg2+具有选择性识别的荧光探针.

     

    Abstract: A good water-soluble fluorescence probe 8-dansyl-aminoquinoline (DK) was synthesized and characterized. The probe showed fluorescence recognition and detection to copper (Ⅱ) or mercury (Ⅱ) ions in aqueous solutions. Upon the addition of Cu2+ and Hg2+, the fluorescent emission intensity of the probe was quenched. Other metal ions did not show similar recognition signals at the same condition. The molecule is a fluorescence probe with selectivity toward Cu2+ and Hg2+.
