摘　　要：通过四(溴甲基)甲烷1与咪唑反应得到含有四个咪唑功能基的化合物2,再以其作为中间体,利用其独特的结构,设计合成了四咪唑鎓盐3、4;采用核磁滴定法,研究了四咪唑鎓盐3、4对Cl-、Br-离子的识别;结果显示,主体化合物对Cl-、Br-离子分别有显著的识别能力.Tetra-imidazolium salt 3 and 4 were synthesized via the intermediate 2 reacted with iodomethane and 2, 6-bis（bromomethyl） pyridine.The compound 2 which had a unique structure, containing four imidazole functional groups, can be prepared by the reaction tetra（bromomethyl） methane 1 and imidazole. Results showed that host compounds 3 and 4 had significant recognition ability for chloride ion, bromide ion by the method of 1HNMR titration.
