摘要
以二茂铁甲醛、1,1'-二茂铁二甲醛、2,6-二氨基吡啶、2-氨基-7-甲基-1,8-萘啶等为原料合成了二茂铁单臂和双臂衍生物Fe L1~Fe L4,并通过核磁共振氢谱、碳谱、质谱和元素分析等对衍生物的结构进行了表征和鉴定,同时用循环伏安法研究了四种衍生物的电化学性质.通过紫外可见分光光度法和核磁滴定,研究了四种衍生物与金属离子的相互作用.结果表明,二茂铁吡啶衍生物Fe L1和Fe L2能够在15种混合金属离子中特异性识别铜离子和铬离子,二茂铁萘啶衍生物Fe L3和Fe L4能够在15种混合金属离子中特异性识别铬离子,这种方法在体外环境污染监测和体内金属离子超标检测中都具有潜在的应用.
A series of ferrocenyl derivatives FeL1-FeL4 were synthesized by ferrocenyl aldehyde, 1,1＇-ferrocene-dicarboxaldehyde, 2,6-diaminepyridine and 2-amine-7-methyl-1,8-naphthyridine. Their structures were characterized by NMR, MS and element analysis. Cyclic voltammetry（CV） was carried out to observe their electrochemical properties. The interactions between Fe L1-FeL4 and metal ions were investigated by UV-Vis and NMR titration. The results indicated that the derivatives FeL1 and FeL2 showed a very good special recognition to Cu^2＋ and Cr^3＋, and the derivatives FeL3 and FeL4 showed an excellent special recognition only to Cr^3＋ in the mixed solution contained fifteen kinds of metal ions. Thus, this method has potential applications in the monitoring of vitro environmental pollution and in the detection of vivo metal ions, which exceed the standard.
