Cluster nuclearity control and modulated hydrothermal synthesis of functionalized Zr-12 metal-organic frameworks

摘要

The synthesis of chemically stable metal-organic frameworks (MOFs) in benign solvents is a key step towards their scalable production and commercialization. Extending the modulated hydrothermal (MHT) synthesis approach for zirconium (Zr) MOFs, we herein demonstrate cluster nuclearity control over the secondary building units (SBUs) to target Zr-6-based and Zr-12-based phases for the Zr terephthalate (Zr-BDC) system. Different functional groups (-NH2, -NO2, -Br, -F-4) can be incorporated into Zr-12-BDC, providing an avenue to further tune the chemical properties of these promising MOFs.
