摘　　要：以1,4-二羟基萘,N-叔丁氧羰基-1,2-乙二胺和二茂铁为原料,合成了一种对Hg^(2+)具有双重识别功能的探针分子(Fc L),其结构经~1H NMR和元素分析表征。采用DPV和FL研究了Fc L对Hg^(2+)的识别性能。结果表明:在混合溶剂(MeOH-H_2O)中,FcL对Hg^(2+)有电化学和荧光识别性能。荧光方法对Hg^(2+)的线性检测范围为1.3×10^(-7)~5.6×10^(-6)mol·L^(-1),检出限为3.5×10^(-8)mol·L^(-1)。Adual-function probe(FcL)for Hg2+was synthesized from1,4-dihydroxynaphthalene,N-Boc-ethylenediamine and ferrocene.The structure was characterized by1H NMR and elemental analysis.The recognition property of FcL on Hg2+was investigated by DPV and FL.The results showed that Hg2+was identified by electrochemical and fluorescence in methanol-H2O.The fluorescence method for the determination of Hg2+exhibits a dynamic response concentration range of1.3×10-7~5.6×10-6mol·L-1with a detection limit of3.5×10-8mol·L-1.
