This book documents the latest research progress in MOF/COF-polymer hybrid materials and reviews and summarises hybridization strategies to achieve MOF/COF polymeric composites.

In this book, the authors present topical research in the study of coordination polymers and metal organic frameworks. Topics discussed include hybrid vanadates and metal organic frameworks; structure and magnetic properties of mono- and poly-nuclear complexes containing Re(IV)l; metal organic framework applications in the fields of hydrogen storage and catalysis; MOF-Based mixed-matrix-membranes for industrial applications; coordination polymers in heterogeneous catalysis; high pressure gas storage on porous solids; metal organic frameworks for CO2 capture and halogen bonding in the assembly of high-dimensional supramolecular coordination polymers.

Since first discovered some two decades ago, metal-organic frameworks (MOFs) have shown interesting properties with regard to storage, separation, and catalysis applications. While MOFs have shown promise in these arenas over the years, a major shortcoming of these materials is their inherently crystalline form factor which hinders their applicational. To circumvent this issue, we have turned to the hybridization of MOFs with polymers in an effort to form a material that has the desired properties of the MOF and the flexibility of the polymer. In particular, we seek to develop novel textile based (nylon based or spray coated) MOF-polymer hybrid materials that are catalytically active against harmful organophosphorus chemical warfare agents (CWAs). Chapter 2 describes the synthesis of a MOF-nylon hybrid material through and interfacial postsynthetic polymerization (PSP) method. The hybrid material contains 29 weight percent MOF and shows catalytic activity against a CWA simulant. Importantly, the covalent MOF-nylon material displays about a seven-fold increase in activity compared to physically mixed controls. In Chapter 3, we screened a wide range of MOFs with varying organic functional groups to establish structure activity relationships (SAR) between MOF functional groups and CWA simulant degradation. The Zr-based MOF UiO-66 (UiO = University of Oslo) was synthesized with either mixed ligand functional groups or halogenated functional groups. We determined that the mixed ligand approach improves CWA activity by three-fold whereas the UiO-66-Iodine MOF displays a fourfold increase in activity. Through theoretical calculations, the increased activity in UiO-66-I was determined to be an artifact of halogen bonding with the CWA simulant. In Chapter 4, we combined the approaches from Chapter 2 and 3, by using the commonly known pseudohalogen isothiocyanate (NCS) functional group in UiO-66 to improve the catalytic activity against CWAs and covalent PSP sites. The UiO-66-NCS MOF was synthesized via postsynthetic modification (PSM) and displayed a ~20 fold increase in activity compared to the presynthetic MOF. More importantly, using amine terminated polypropylene oxides, MOF-polymer material was formed, and spray coated onto textile fibers. This material showed great durability and catalytic activity compared to physically mixed controls. Chapter 5 describes the room temperature synthesis of the commonly used UiO-66 MOF as well as a few functional groups derivatives. Starting from a UiO-66-F4 MOF with relatively labile ligands, postsynthetic exchange (PSE) with four different MOF ligands at room temperature in aqueous conditions was performed with almost complete ligand exchange. These MOFs were thoroughly characterized after PSE and maintained desired properties such as crystallinity and particle size or shape.

Document from the year 2022 in the subject Chemistry - Macromolecular Chemistry, Polymer Chemistry, grade: 17, Gauhati University, language: English, abstract: Porous coordination polymers, also known as metal organic frameworks are a new type of hybrid material constructed via self-assembly of metal ions/metal clusters which function as nodes and organic ligands which act as bridges or linkers. They are one of the earliest developed classes of metal containing polymers. They extend infinitely one, two or three dimensional framework through coordination bonding, hydrogen bonding, π–π stacking, C-H-π interactions as well as van der Waal forces. These weaker non-covalent interactions, are important for the packing of the one dimensional chains, two-dimensional nets and three-dimensional frameworks. In view of the tunable structures and promising properties shown by these systems various complexities have been prepared and thoroughly investigated over last decade. MOFs are currently flourishing fields of research owing to their intriguing structural motifs and various potential applications, in the field of gas storage, gas separation, catalysis, ion exchange, microelectronics, non linear optics, sensors, medicine and molecular magnetism etc. They possess structural regularity, high porosity, high surface area resulting in greater potential applications than conventional zeolites or activated carbons and mesoporous silica. For the construction of porous coordination polymers with diverse structures and properties selection of the special inorganic and organic building blocks is one of the important factors. Multicarboxylate organic ligands have proved to be an excellent choice for the construction of MOFs of higher nuclearity due to their different coordination modes with the metals, molecular flexibilities and structural stabilities. Metal carboxylate linker in combination with cross linked or pillered polypyridine have generated many interesting coordination architecture. Making use of transition metal carboxylate and linear bridging auxiliary ligands it is possible to construct 1-D, 2-D and 3-D porous coordination polymer of different pore structures and porosities. Aside from coordination bonding interactions, various non-covalent bonding or some weak intra- or intermolecular interactions, such as hydrogen-bonding, π–π stacking and C–H–π interactions or van der Waals interactions also influence the formation of final architectures.

Metal-Organic Frameworks (MOFs) are crystalline compounds consisting of rigid organic molecules held together and organized by metal ions or clusters. Special interests in these materials arise from the fact that many are highly porous and can be used for storage of small molecules, for example H2 or CO2. Consequently, the materials are ideal candidates for a wide range of applications including gas storage, separation technologies and catalysis. Potential applications include the storage of hydrogen for fuel-cell cars, and the removal and storage of carbon dioxide in sustainable technical processes. MOFs offer the inorganic chemist and materials scientist a wide range of new synthetic possibilities and open the doors to new and exciting basic research. Metal-Organic Frameworks Materials provides a solid basis for the understanding of MOFs and insights into new inorganic materials structures and properties. The volume also reflects progress that has been made in recent years, presenting a wide range of new applications including state-of-the art developments in the promising technology for alternative fuels. The comprehensive volume investigates structures, symmetry, supramolecular chemistry, surface engineering, recognition, properties, and reactions.
