摘　　要：应用紫外-可见吸收光谱和荧光光谱考察了N-对氯苯甲酰基-N'-芳酰氨基硫脲在二甲基亚砜(DMSO)中与F-、Cl-、Br-、I-、CH3CO2-和HSO4-的相互作用。结果表明,该类主体分子b和d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-有突出的响应灵敏度,可选择性识别F-。In the paper,regarding N-p-chlorobenzoyl-N′-aroyl thiosemicarbazides as host molecules,the binding properties with ani-ons such as F-, Cl-, Br-, I-, CH3 CO2- and HSO4-in DMSO were examined by UV-Vis and fluorescence spectrum. The results showed that a 1∶1 stoichiometry complex was formed between compound （ b or d） and anions by hydrogen-bonding interaction. The results showed that the receptor （ b or d） had a better selectivity for F-obviously.
