ABSTRACT
This chapter discusses different postsynthetic modification (PSM) methods that have found frequent application in the synthesis of mesoporous Metal-Organic Frameworks (MOFs) for different applications, specifically as sorbents and heterogeneous catalysts. The modified MOF was characterized by chemical analysis, adsorption of argon, nitrogen and water vapors, powder x-ray diffraction (XRD), thermo gravimetric analysis (TGA), solid-state NMR, and Fourier transform infrared (FTIR) spectroscopy. The liporeductor caffeine has been selected as a model compound for small-molecule heterocyclic drugs, for proof-of-principle encapsulation on mesoporous MOFs that have been post synthetically modified by adsorption of heparin. Absorption of visible light is thought to occur in MIL-100(Fe), which has the suitable optical absorption spectrum and a distinct color, while supported metallic palladium nanoparticles constitute a common photo catalytic promoter among the metal-doped oxide photocatalysts. The nanoparticles of metallic palladium in Pd@MIL-100 (Fe) are believed to assist in the separation of the photoexcited electron and hole formed in the MOF upon absorption of light.
