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Cu2+,Hg2+,Pb2+,Zn2+,Ni2+和Cd2+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Cu2+有响应,溶液由无色变成红色;而其荧光光谱对Hg2+和Cu2+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。

关 键 词:8-氨基喹啉取代苯甲酰胺衍生物  吸收光谱  荧光增强      分子识别

Abstract: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 Cu2 +,Hg2 +,Pb2 +,Zn2 +,Ni2 + and Cd2 + via its absorption and fluorescence spectra.The recognition mechanism and binding mode were discussed.The results showed that 8-AQ derivatives 1 coordinated with Cu2 + can induce a new absorption peak at 509 nm,which turned the solution to red from colorless.In acetonitrile Hg2 + and Cu...
Keywords:8-Aminoquinoline derivatives  Absorption spectra  Fluorescence enhancement  Copper  Mercury  Molecular  Recognition
