Problems solved by technology

At present, metal-organic coordination polymers with simple indium ions as the central node are relatively common, and their organic ligands are mostly aromatic organic molecules containing carboxylic acids. The three-dimensional metal-organic framework structure constructed by indium and trimesic acid shows good performance. The gas adsorption performance; the coordination polymer with the indium-copper bimetal as the central node is receiving more and more attention; and the coordination polymer with the indium-potassium-copper trimetallic ion as the central node in the crystal structure has not yet been reported

Description

technical field [0001] The invention belongs to the technical field of coordination chemistry, and in particular relates to an indium potassium copper trimetallic coordination polymer crystal and a preparation method and application thereof. Background technique [0002] Metal-organic coordination polymers are a new type of functional crystalline material formed by coordination bonds between metals and organic ligands. This material has important applications in the fields of luminescent materials, organic catalysis, and gas adsorption and separation. Metal ions in metal-organic coordination polymers are used as central nodes to connect with organic ligands to form one-dimensional, two-dimensional or three-dimensional crystal structures through coordination self-assembly. The metal ions in this type of material can be single metal ions, double metal ions or multi-metal ions. However, metal-organic coordination polymers constructed with multiple metal ions often exhibit diff...
