Inorganic-organic hybrid material of polyacid-based silver complex, and preparation method and application thereof

Abstract

The invention discloses an inorganic-organic hybrid material of a polyacid-based silver complex, and a preparation method and application thereof, belonging to the technical field of macromolecular compounds. The molecular formula of the inorganic-organic hybrid material is [Ag(C8H8N3)(Mo3O10)]. According to the invention, the organic ligand 2-(pyridin-3-yl)-1H-imidazole(C8H8N3) is obtained through an in-situ decarboxylation reaction of 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarboxylic acid (C10H7N3O4); one-dimensional isopolyacid (Mo3O10)2-chain structures are connected by Ag<+> to form two-dimensional inorganic layered structures; the protonated organic ligand 2-(pyridin-3-yl)-1H-imidazole and Ag<+> are coordinated and are positioned at two sides of the inorganic layered structure; and theadjacent layered structures form a three-dimensional supramolecular network structure through Pi...Pi accumulation action force among the interlaminar organic ligands. The preparation method is simpleprocess; synthesis raw materials are cheap and easy to obtain; and reaction conditions are mild.

Description

Technical field [0001] The invention belongs to the technical field of polymer compounds, and particularly relates to an inorganic-organic hybrid material of a polyacid-base silver complex, and a preparation method and application thereof. Background technique [0002] Polyoxometalates (polyacids) are a type of polynuclear metal oxides. From the structural point of view, polyacids have a large number of oxygen atoms, large anion clusters, and metal centers are usually in the highest oxidation state. In terms of physical and chemical properties, polyacids have both oxidation and reduction properties, high thermal stability and structural tunability, so they can be used in catalysis, medicine, optics and other fields. Inorganic-organic hybrid materials based on polymolybdates have received extensive attention from scientific researchers due to their structural diversity and excellent performance. Although there are already some questions about [Mo 3 O 10 ] 2- The literature report...
