Abstract

The invention discloses a preparation method and application of a ferrocyclamine compound sensing material. The method is to prepare a water-soluble ferrocyclamine compound by the ring-closure reaction of ferrocenecarboxaldehyde and 1,2-di(aminoethoxy)ethane. The ferrocyclamine compound can be used as a sensing material for identifying anions by an electrochemical cyclic voltammetry method and has high sensitivity to H2PO4<->, HSO4<-> and F<->.

Description

technical field [0001] The invention relates to a sensing material preparation technology, in particular to a preparation method and application of a ferrocenyl cyclic amine compound sensing material. Background technique [0002] The ferrocene group has stable redox characteristics and chemical activity, and has been proven to be one of the most effective electrochemical signal transmission groups. Designing anion recognition receptors containing ferrocene groups has always been the focus and focus of research. . Generally, the determination of the presence of anions is easily affected by solvents, especially in highly polar aqueous solutions. Although it is more practical to effectively identify anions in aqueous environments, the progress in anion identification in aqueous solutions has been slow. . (P.D.Beer, Zheng Chen, et al., [J].Inorgnaica Chemica Acta., 1996, 246, 143-150;) Cyclic amine compounds have good water solubility, variable ring size, and can be matched b...
