Abstract

The invention discloses a two-dimensional ultra-microporous crystalline rare earth coordination polymer with a stable structure as well as a preparation method and application of the two-dimensional ultra-microporous crystalline rare earth coordination polymer. The rare earth coordination polymer obtained by assembling and synthesizing a 4, 4 '4' '-triformic acid triphenylamine ligand and rare earth ions La < 3 + > has a two-dimensional through ultra-microporous structure, so that the material transmission speed of small molecules in the microporous structure is increased, so that CO2 gas adsorption can reach adsorption saturation more quickly, and meanwhile, the fluorescence response rate is also improved in fluorescence sensing application. The specific crystal material synthesized by the invention is applied to gas adsorption (including but not limited to CO2 molecules), fluorescence luminescence and fluorescence sensing.

Description

technical field [0001] The invention belongs to the field of coordination polymers, and in particular relates to a structurally stable two-dimensional ultra-microporous crystalline rare earth coordination polymer, a preparation method and an application thereof. Background technique [0002] Porous coordination polymers, also known as metal-organic framework compounds, are a class of crystalline porous inorganic-organic hybrid materials composed of metal ions and organic ligands. Compared with traditional inorganic molecular sieves, porous coordination polymers have the advantages of diverse structures, high specific surface area, and easy modification, and can be used in the fields of adsorption, separation, molecular recognition, and catalysis. According to the definition and classification of pore size by the International Union of Pure and Applied Chemistry (IUPAC), micropores with a pore size of 0.7-2.0 nanometers are called supermicropores, and micropores with a pore s...
