| titleOfInvention | A kind of probe for detecting copper ion and zinc ion and preparation method and application |
| abstract | A probe for detecting copper ions and zinc ions is an imine derivative of [5] helicene. It is complexed with copper ions, resulting in obvious absorption peaks in the visible light region, and copper ions can be detected by ultraviolet-visible spectroscopy. It complexes with zinc ions, and the fluorescence increases, and the zinc ions can be detected by fluorescence spectroscopy. The preparation method is as follows: firstly the [5] helicene compound with a hydroxyl group reacts with chloromethyl methyl ether, continues to react with butyllithium and DMF to introduce a formyl group at the ortho position of the hydroxyl group, and continues to react with an amino compound to generate [5] helicene Imine Derivative DC. The advantages of the present invention are: the helicene derivative DC prepared by the present invention is simple and convenient to synthesize, has high yield, is easy to prepare, and is suitable for scale-up synthesis and practical production application. The ultraviolet-visible absorption spectrum can be used to detect divalent copper ions, and the fluorescence method can be used to detect divalent zinc ions, which can be applied to the field of ion detection as a novel probe. The probe molecule has good selectivity and high sensitivity, has the advantages of fast response and obvious phenomenon, and has broad application prospects. |
