摘　　要：将苯并氮杂-15-冠-5的边臂链接到4,4'-联吡啶上,设计合成了3种冠醚环修饰的紫精化合物。运用紫外光谱考察了其识别碱金属离子的能力,运用循环伏安测试考察了其电化学氧化还原性质。紫外光谱测试结果显示,含有两个冠醚环的紫精化合物对金属离子有较显著的配位作用。循环伏安测试结果显示,氯化1,1'-双[2-酮-2-(苯并氮杂-15-冠-5)]-4,4'-联吡啶盐化合物具有更好的电化学信号,出现了两对可逆的氧化还原峰。Three kinds of viologens modified by crown ethers have been synthesized via the reaction of 4,4＇-bipyridine with benzoaza-15-crown-5.The recognition abilities towards alkali metal ion were evaluated by UV-Vis and the electrochemical redox characters were investigated using cyclic voltammetry.The result of UV-Vis shows that viologen with two crown ethers has a significant coordination with alkali metal ion. The cyclic voltammetry also indicates that chloride 1,1＇-bis（ 2-（ 2,3,5,6,8,9,11,12-octahydro-7H-benzo[e][1,4,7,10]tetraoxa[13]azacyclopentadecin-7-yl）-2-oxoethyl）-[4,4＇-bipyridine]-1,1＇-diium with better electrochemical signals has two pairs of reversible redox peaks.
