Harnessing mechanochemistry for direct synthesis of imine-based metal-organic frameworks

Patent published on the 2026-06-25 in US under Ref US20260176291 by UNIV OHIO [US] (Tegudeer Zhuorigebatu [us], Gao Wenyang [us])

Abstract: The growth of metal-organic frameworks (MOFs) is most frequently accessed by direct assembly of metal cations and multitopic ready-to-connect ligands under solvothermal conditions. However, such nonambient conditions are expected to impose a synthetic challenge to incorporate degradable ligands into MOFs. This explains why imine-based MOFs are scarce, as the imine motif is usually prone to decompose through hydrolysis. This work not only showcases mechanochemistry as an ambient, sustainable, and[...]


Our summary: This study demonstrates the use of mechanochemistry for synthesizing imine-based metal-organic frameworks (MOFs). It addresses the challenges of incorporating degradable ligands by integrating ligand synthesis and MOF growth into one step. The approach offers a sustainable and efficient method for producing these historically difficult materials.

Abstract: Efficiently separating propene and propane is paramount for the chemical industry but notoriously difficult due to their minimal size and volatility differences. Here, an efficient strategy to overcome this separation challenge was demonstrated through the design of bimetallic zeolitic imidazolate framework (ZIF)-based mixed-matrix membranes (MMMs). Thin-film composite (TFC) membranes were fabricated by integrating monometallic ZIF-8, ZIF-67, and a synergistic bimetallic ZIF-8-67 into a uniquely[...]
