Abstract

The invention relates to a 3,3',5,5'-cobalt azobenzoate (II) metal-coordination polymer and a synthesizing method and application thereof and belongs to the technical field of fluorescence detection materials. The metal-coordination polymer takes cobalt as a metal center, 3,3',5,5'-azobenzoic acid oxide H4L as a main ligand and phenanthroline phen as an ancillary ligand, and the experimental formula of the coordination polymer is described as ((Co3(phen)2(HL)2) (H2O) 2)n, and the molecular formula is describes as C56H34Co3N8O2O. The preparation of the final product is simple in method and easy to implement, and the yield is as high as 69.9%; in addition, the metal-coordination polymer is applicable to fluorescent sensor materials, capable of recognizing Fe<3+>ions in a short time and highin flexibility, and high reference value in detection of the Fe<3+> in the human body and good application prospect are achieved.

Description

technical field [0001] The invention belongs to the technical field of fluorescence detection materials, and more specifically, the invention relates to a cobalt (II) metal coordination polymer of 3,3',5,5'-oxymellitate tetracarboxylate and its synthesis method and application. Background technique [0002] Metal-organic coordination polymers, also known as metal-organic frameworks (Metal-Organic Frameworks, referred to as MOFs) materials, it is a periodic arrangement formed by the coordination of metal ions and organic ligands, which can be in three-dimensional space The extended new material is also a new type of functionalized crystal material that has received extensive attention in recent years. In MOFs, the arrangement of organic ligands and metal ions or clusters has obvious directionality, which can form different framework pore structures. Because of their advantages such as structural designability and functional specificity, this new type of material is widely use...
