中文摘要：

设计合成了可识别金属离子的荧光传感分子8-氨基喹啉取代苯甲酰胺衍生物,通过核磁共振谱和质谱表征其结构;利用其光谱性质研究了该系列物质对过渡金属离子Cu^2＋,Hg^2＋,Pb^2＋,Zn^2＋,Ni^2＋和Cd^2＋的识别性质,初步探讨了其识别机理。实验表明：在乙腈中,8-氨基喹啉苯甲酰胺的吸收光谱在509nm处对Cu^2＋有响应,溶液由无色变成红色;而其荧光光谱对Hg^2＋和Cu^2＋有良好的选择性,荧光增强倍率分别高达368和192,与金属离子形成结合比为1：1配合物。

英文摘要：

The novel 8-Aminoquinoline（8-AQ） derivatives receptor was designed and synthesized.Its structure was characterized by NMR and ESI-MS.It was investigated to recognize metal ions such as Cu^2 ＋,Hg^2 ＋,Pb^2 ＋,Zn^2 ＋,Ni^2 ＋ and Cd^2 ＋ via its absorption and fluorescence spectra.The recognition mechanism and binding mode were discussed.The results showed that 8-AQ derivatives 1 coordinated with Cu^2 ＋ can induce a new absorption peak at 509 nm,which turned the solution to red from colorless.In acetonitrile Hg^2 ＋ and Cu^2 ＋ induced dramatic enhancement in the fluorescence of the derivation 1 by 368 and 192 folds.Job plot showed 1：1 stoichiometry between 8-AQ and Cu^2 ＋ or Hg^2 ＋.
