摘　　要：应用紫外-可见吸收光谱和荧光光谱考察了一种酰胺硫脲类衍生物在二甲基亚砜(DMSO)中与F-、Cl-、Br-、CH3CO2-、H2PO4-和HSO4-的相互作用。结果表明,该类主体分子能与阴离子形成结合比为1:1的氢键配合物,荧光光谱显示它们对F-和H2PO4-有突出的响应灵敏度,可选择性识别F-和H2PO4-。In the paper, the binding properties of the amide thiourea derivative with anions such as F-, CI-, Br-, CH3 CO2-, H2PO4- and HSO4 - in DMSO were examined by UV-Vis and fluorescence spectrum. The results indicated that a 1 ： 1 stoiehiometry complex was formed between compound and anions by hydrogen-bonding interaction. The results showed that the receptor had a better selec- tivity for F-and H2PO4-.
