Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Recommanded Product: 7331-52-4, 7331-52-4, Name is (S)-4-Hydroxydihydrofuran-2(3H)-one, molecular formula is C4H6O3, belongs to Tetrahydrofurans compound. In a document, author is Zhang, Ying-Peng, introduce the new discover.
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.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 7331-52-4. Recommanded Product: 7331-52-4.
