| Outline of Final Research Achievements |
Controlling the particle size and shape of soft metal-organic framework compounds is crucial for understanding and regulating the adsorption-induced structural transitions that lead to the unique stepwise adsorption behavior of these materials. In the present study, we synthesized zeolitic imiazolate framework-8 (ZIF-8), which is a subclass of soft MOFs, and demonstrated that the intensive mixing facilitated by a microreactor enables the synthesis of monodisperse ZIF-8 particles with high reproducibility. The technique proposed in this study is additive-free and allows control of both particle size from 50 nm to 2 um and particle shape from cube to chamfered cube to rhombic dodecahedron, simply by adjusting the concentration of feed solutions and reaction temperature. Furthermore, we demonstrate that both particle size and particle shape are key physical parameters determining the adsorption characteristics of ZIF-8 particles.
