π-Conjugated (1-4) and partially reduced (5) macrocyclic Schiff bases have been obtained by proton-template condensation of 2,6-diformyl-4-R1- phenol (R1 = Me, t-Bu) with 1,2-diamino-4,5-R2-benzene (R2 = H, Me).

A series of new macrocyclic binuclear copper(II) complexes of the type [Cu2L1–5(ClO4)](ClO4) (1–5) were synthesized by template condensation between precursor compounds 2,6-bis(4-aminoethylpiperazin-1-ylmethyl)-

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.
