Abstract: An ordered macroporous metal-organic framework single crystals and a preparation method therefor. In the method, a three-dimensional structure constructed by polymer microspheres is used as a template; 2-methylimidazole and zinc nitrate, precursors of MOFs, are firstly deposited in the three-dimensional template; the three-dimensional template containing the precursors is soaked in a mixed solution of ammonia water and methanol subsequently, and the three-dimensional template is taken out after crystallization; the three-dimensional template is soaked in an organic solvent to remove the macromolecular three-dimensional template, and the ordered macroporous MOF single crystals is obtained through centrifugal separation. The ordered macroporous MOF single crystals have a basic framework of zeolitic imidazolate framework-8, and structurally include highly-ordered macro-pores whose pore size may be controlled to be between 50 and 2000 nm based on a size of the used template.
