Preparation method and application of mercaptan fluorescence probe based on coumarin

The invention discloses a preparation method and application of a mercaptan fluorescence probe based on coumarin. The preparation method includes: coumarin and p-tert-butylphenol dialdehyde are used as raw materials to synthesize a bis-Schiff base coumarin derivative (compound I), the compound I has strong fluorescence, and the compound I is coordinated with copper ions to prepare coumarin-copper ion (II) complex, namely the mercaptan fluorescence probe I-Cu (II). Due to the influence of the paramagnetism of Cu2+ and photoinduction electron transfer effect, the fluorescence of the compound I is quenched; sulfur atoms in compounds such as mercapto-amino acid and derivatives such as glutathione thereof and Cu2+ have a strong coordination effect, the competitive coordination effect allows the copper ions in the coumarin-copper ion (II) complex to be taken away by the mercapto-amino acid and the derivatives thereof so as to regenerate the compound I, and the fluorescence of the compound I is restored. Accordingly, a method for fast and simply detecting mercaptan compounds is built.
