Abstract

The invention provides a method for synchronizing microporous aluminum-base coordination polymers. The method includes the following steps of utilizing Al(NO3)3 9H2O and ligand, 1,4-naphthalene diacid as raw materials and water as solvent, subjecting the raw materials to reaction for 2-32 hours at the temperature of 40-80 DEG C in 250W, filtering the obtained solution untile the temperature falls to the room temperature, and sequentially washing with deionized water, N,N-dimethylformamide and ethanol, drying at the room temperature and obtaining the microporous aluminum-base coordination polymers. The method for synchronizing microporous aluminum-base coordination polymers has the advantages of operable simplicity, high yield, simple posttreatment, fastness and environment-friendliness and the like.

Description

technical field [0001] The invention relates to a method for preparing an aluminum-based coordination polymer by a microwave method. The invention has the characteristics of simple operation, high yield, simple post-treatment, rapidity and environmental protection. Background technique [0002] Metal-organic porous coordination polymers (metal-organic framework, MOF) are formed by supramolecular self-assembly of metal ions and organic ligands. This complex can synthesize metal-organic frameworks with different pore structures by complexing different metal ions with various rigid organic ligands, and can carry some functional modification genes on the organic ligands (such as Br, -NH 2 etc.), making this complex more unique and functional in structure. As early as the mid-1990s, the first class of MOFs were synthesized, but their porosity and chemical stability were not high. Therefore, scientists began to study new types of coordination polymers formed by cations, anions...
