摘　　要：设计合成了含有苯环基团支链的1,4,7,10-四氮杂环十二烷(Cyclen)全同取代衍生物1,4,7,10-四(2-对甲氧基苯氧基)乙基-1,4,7,10-四氮杂环十二烷2.化合物2的分子中含有一个Cyclen底座和4条醚链侧臂,前者易与金属离子配位,后者可通过弱相互作用形成一个富电子空穴,具有形成主-客体超分子结构的潜能.利用化合物2与碱金属盐(Li Cl或Li Br)的作用,制备了配合物3和4,并经1H NMR确证了其结构.探讨了化合物1,2,3和4的1H NMR及荧光性能的变化,发现配合物3和4 Cyclen环(NCH2CH2N)上的氢裂分为2个,且荧光强度大大增强.The tetra-N-alkylations of 1,4,7,10-tetraazacyclododecane （ Cyclen ） derivative 1,4,7,10- tetrakis （ 2-（ （ 4-methoxy ） phenoxy ） ethyl ）-1,4, 7, 10-tetraazacyclododecane 2 with pendant-armed benzene was designed and prepared with one Cyclen base and four hydroquinone groups of benzene ring. Cyclen base is easily to coordinate with metal ion, and hydroquinone groups can form w-electron-rich cavity by stacking interaction. Two complexes of 3 and 4 were prepared by the reactions of 2 with LiBr and LiCl through an improved synthetic technique. The structure was confirmed by ^1H NMR. The chemical shifts of the peaks and fluorescence spectra of 1,2, 3 and 4 were investigated. The results show that hydrogen atoms of NCH2CH2N in 3 and 4 Cyclen unit are split into two to increase the fluorescence intensity obviously.
