Abstract:

A fluorescent probe CMD-Zn2+ based on zinc complexes was constructed for NO detection, Ligand CMD was prepared by naphthalene and furanide and ligonidaldehyde by condensation reaction. The ligand CMD was combined with zinc ions to form the probe CMD-Zn2+. The probe CMD-Zn2+ could specifically recognize NO. The recognition performance of probe CMD-Zn2+ was examined by fluorescence spectroscopy and UV absorption spectroscopy, and the structure of CMD was characterized by high-resolution mass spectroscopy(HRMS) and nuclear magnetic resonance hydrogen spectroscopy(1H NMR). The experimental results showed that in the presence of other competing ions, the probe CMD-Zn2+ specifically recognized NO, and the detection limit of NO recognition was 8.23×10‒9 mol/L. The probe CMD-Zn2+ has been successfully applied in fluorescence imaging studies in cells and live mice.
