  • Title: Exploiting Microwave Chemistry for Activation of Metal-Organic Frameworks.
    Author: Lee EJ, Bae J, Choi KM, Jeong NC.
    Journal: ACS Appl Mater Interfaces; 2019 Sep 25; 11(38):35155-35161. PubMed ID: 31483139.
    Abstract:
    Microwave is thought of as a useful electromagnetic radiation tool because it is often used in real life as well as in a variety of chemical processes. Meanwhile, activation of metal-organic frameworks (MOFs), which must be essentially done to remove coordinating and pore-filling solvents before the use of MOFs for various applications, has been performed commonly with the methods of heat supply or solvent exchange. Here, we show a new methodological microwave activation (MA), realizing it with various MOFs such as HKUST-1, UiO-66, and MOF-74s. For instance, microwave irradiation to the MOF samples for 4-35 min leads to the complete activation of the MOFs without structural damage. As described below, we further demonstrate that the solvent-assisted MA, which is the MA process performed after the solvent exchange, can substantially reduce the time for the activation by 4 min.
