Synthesis And Recognition For Cu²⁺ Ion Of Monosubstituited And 1,1’-Disubstituted Ferrocene Derivatives Containing [1,2,3]-Triazole

Metal ions plays a very key role in human life and health, but the heavy metal ions easily enriched in the ecosystem, which can produce great toxic to people and organisms. Thus, Detection and Separation technology of metal pollutants have very important significance in environmental protection and so on. Naphthalene and quinoline compounds is a kind of important aromatic heterocyclic compounds, and its special structure makes this kind of compounds a great application value in the fields such as medicine and super molecular recognition. Due to some organic fluorescent probes are easy to synthesis, quick response, the advantages of high sensitivity and good selectivity, it has a broad application prospect in the field of metal ion detection.Based on ferrocene triazole naphthalene and quinoline derivatives as the foundation, the article designs and synthesis a variety of organic fluorescent probes.After using IR,¹H NMR,¹³C NMR and HRMS to characterize the target compounds and using UV-vis spectroscopy, fluorescence spectroscopy, electrochemical cyclic voltammetry （CV） and differential pulse voltammetry （DPV） with the metal ions to screen, it is easy to find that NSZ1、KSZ1 have good ability to recognize Cu2+ ion. The color vary widely after Cu2+ ion was added, which the naked eye can identify is a advantages of such probes. The fluorescence changes of quinolyl ferrocene triazole compounds also can be observed after Cu2+ ion was added under fluorescent light（365nm）, which greatly improves the efficiency of our detection of ions.
