Bottom‐Up Assembly from a Helicate to Homochiral Micro‐ and Mesoporous Metal–Organic Frameworks

Nanoscale Hierarchically Porous Metal–Organic Frameworks: Facile Synthesis, Mechanism Research, and Application

“…To date, considerable efforts have been made to develop effective and reliable synthetic strategies of H-MOFs, including long-ligand method, post-synthetic modification, and template-assisted synthesis. , However, most studies in the field of H-MOFs have only focused on the generation of mesopores but seldom pay attention to the topic of crystal size and synthesis conditions. , For instance, the crystal size of the H-MOFs usually belongs to micrometer-scale construction rather than the nanoscale, − in which the bulk crystal (micrometer scale) is unfavorable for the mass transporting of the reactants and products to/from active sites located inside the micropores . Furthermore, with regard to the practical application of H-MOFs, a facile and rapid synthetic process for the large-scale fabrication of H-MOF materials will be of great value. , Nonetheless, the synthesis methods of H-MOFs usually require a complicated synthetic procedure and harsh conditions such as high temperatures, high pressures, and being time consuming (>12 h). ,,, Consequently, these requirements will result in energy consumption and potential risk and render the large-scale commercialization of H-MOFs to be a formidable task . To solve these issues, multiple advanced methods have been developed to rapidly synthesize H-MOFs at room temperature and pressure, including ionic liquid approaches, composites method, and cooperative template strategy .…”
