A preparation method for a water-soluble fluorescent probe that specifically recognizes zinc ions, the compound name is 8-[4'-N-((2-ethoxy)ethanol)methylaminobenzoyl]methylquine Phyline, the chemical molecular formula is C 22 H 24 N 4 O 3 , and the molecular structural formula is: The preparation method is: use methyl p-formylbenzoate and diglycolamine as raw materials to form a Schiff base, and then undergo a reduction reaction and a hydrazinolysis reaction to form 4-N-[(2-ethoxy)ethanolmethylamino]benzyl Hydrazide, which reacts with quinoline-8-carbaldehyde to form the target compound. The advantages of the present invention are: the preparation method has simple process, readily available raw materials, and is easy to implement; the prepared fluorescent probe has high selectivity to Zn 2+ , and realizes high-sensitivity detection of zinc ions; The detection of metal zinc ions has important application value. |
