A Novel Fluorescent Probe Based on Pyrazole-Pyrazoline for Fe (III) Ions Recognition
Firstly, a novel pyrazole-pyrazoline fluorescent probe was developed and synthesized. The probe can be used to determine Fe(3+)ions in a series of cations in tetrahydrofuran aqueous solution with high selectivity and high sensitivity. After the addition of iron ions, the fluorescence intensity is significantly reduced, Its structure was characterized by(1)H NMR,C-13 NMR and HR-ESI-MS. UV absorption spectra and Fluorescence spectroscopy were used to study the selective recognition of probeMon metal ions. The probeMcan selectivity and sensitivity to distinguish the target ion from other ions through different fluorescence phenomena. In addition, the binding modes ofMwith Fe(3+)were proved to be 1:1 stoichiometry in the complexes by Job’s plot, IR results. The combination of probeMand iron ions is 1:1, and the detection limit is 3.9 x 10(-10)M. The binding mode and sensing mechanism ofMwith Fe(3+)was verified by theoretical calculations using Gaussian 09 based on B3LYP/6-31G(d) basis.
Reference of 67-51-6, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 67-51-6 is helpful to your research.
