Problems solved by technology

Using this method, several porphyrin-based MOFs with high stability in acidic and neutral aqueous solutions have been developed, such as PCN-222 and PCN-600. An obvious disadvantage of these materials is that they are easily decomposed in alkaline solutions.

Embodiment 1

[0025] The organic ligand H 4 TPP (0.035 mmol) and S nickel acetate tetrahydrate (0.035 mmol) were mixed uniformly in 1 mL of N,N-dimethylformamide, 0.05 mL of triethylamine and 0.05 mL of water were added, and sealed into a vial. Crystals of the metal-organic framework were obtained via thermal reaction at 100° C. for 48 hours.

Embodiment 2

[0027] The organic ligand H 4 TPP (0.035 mmol) and nickel acetate tetrahydrate (0.035 mmol) were mixed uniformly in 1.5 mL of N,N-dimethylformamide, 0.05 mL of triethylamine and 0.05 mL of water were added, and sealed into a vial. Crystals of the metal-organic framework were obtained via thermal reaction at 100° C. for 48 hours.

Embodiment 3

[0029] The organic ligand H 4 TPP (0.035 mmol) and nickel acetate tetrahydrate (0.035 mmol) were mixed uniformly in 2.0 mL of N,N-dimethylformamide, 0.05 mL of triethylamine and 0.05 mL of water were added, and sealed into a vial. Crystals of the metal-organic framework were obtained via thermal reaction at 100° C. for 48 hours.

Abstract

The invention discloses a porphyrin-based metal organic framework material with ultrahigh stability and a synthetic method, and belongs to the technical field of crystalline state materials. The chemical formula of the porphyrin-based metal organic framework material is [Ni9.77C56.64N21.24O10.92H35.47]. Under the closed condition, an organic ligand 5,10,15,20-tetra(1 hydrogen-pyrazol-4-radical) porphyrin(H4TPP) and nickel acetate generate a solvothermal reaction in N,N-dimethylformamide to obtain the porphyrin-based metal organic framework material. The metal organic framework material has ultrahigh stability, and materials of this kind can be possibly applied widely.

Description

technical field [0001] The invention belongs to the technical field of crystalline materials, and the technology relates to metal-organic coordination polymer materials, and is characterized by a synthesis method of a metal-organic framework material based on porphyrin as a ligand and a study on its stability. Background technique [0002] Due to their special properties, porphyrins have very important applications in many fields, such as anticancer drugs, catalysts, photosensitizers, pH sensors and so on. However, it is prone to self-aggregation and agglomeration in its application, which seriously affects the research on the properties of porphyrin compounds. Metal-organic frameworks (MOFs) are constructed by metal ions or metal clusters and organic ligands through coordination bonds. As a new type of porous material, they have regular structure, high porosity, and large specific surface area. , structure and function are easy to control and other characteristics, and hav...
