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 porous crystalline polymers constructed by metal sites and organic building blocks. Since the discovery of MOFs in the 1990s, they have received tremendous research attention for various applications due to their high surface area, controllable morphology, tunable chemical properties, and multifunctionalities, including MOFs as precursors and self-sacrificing templates for synthesizing metal oxides, heteroatom-doped carbons, metal-atoms encapsulated carbons, and others. Thus, awareness and knowledge about MOFs and their derived nanomaterials with conceptual understanding are essential for the advanced material community. This breakthrough new volume aims to explore down-to-earth applications in fields such as biomedical, environmental, energy, and electronics. This book provides an overview of the structural and fundamental properties, synthesis strategies, and versatile applications of MOFs and their derived nanomaterials. It gives an updated and comprehensive account of the research in the field of MOFs and their derived nanomaterials. Whether as a reference for industry professionals and nanotechnologists or for use in the classroom for graduate and postgraduate students, faculty members, and research and development specialists working in the area of inorganic chemistry, materials science, and chemical engineering, this is a must-have for any library.

Metal-organic frameworks represent a new class of materials that may solve the hydrogen storage problem associated with hydrogen-fueled vehicles.

Providing professors, graduate and undergraduate students, structural chemists, physical chemists, and chemical engineers with a historical perspective, as well as the most up-to-date developments by leading experts, Metal-Organic Frameworks examines structure, symmetry, supramolecular chemistry, surface engineering, metal-organometallic frameworks, properties, and reactions.

Composites based on Metal-organic frameworks (MOFs) have exceptional physical and chemical properties and offer a great number of advanced applications in such fields as energy storage, energy conversion by catalysis, sensors for environmental applications, environment safety and industrial wastewater treatments. They also have interesting medical applications, such as encapsulation of enzymes. The present book covers design, synthesis and preparation of various MOFs, as well as the resulting product characteristics: homogenous morphology, small size dispersion, high thermal stability and desired surface area.

This title takes researchers in as well as out of the field of metal-organic framework (MOF) and then guides them on a journey to rediscover and rethink how these designer coordination polymers will influence the realm of materials science. This book opens with a look at a deeply controversial issue, MOF stability, which has plagued many systems, but ultimately has led to better materials that proved to be more robust allowing them to be investigated for multiple applications. This book successfully highlights many of these useful applications that MOFs are well adapted for. Because MOF components, inorganic and organic, can combine the best of both chemical domains, MOFs will improve our environment by removing harmful contaminants from the air and water, reduce the energy required to perform chemical reactions, partition hard to separate molecular mixtures, and form the next-generation of magnetic and electronic materials. MOFs will eventually be used for everyday activities — for monitoring or reacting to changing conditions. Readers of this book can then take note and implement MOFs in their line of research.

In the last two decades, metal-organic frameworks (MOFs) have provoked considerable interest due to their potential applications in different fields such as catalysis, gas storage and sensing. The most important advantages of MOFs over other porous materials is the ability of tailoring their pore size, functionality and even the topology of the framework by rational selection of the molecular building blocks. Therefore, many chemists have tried to engineer the structure of MOFs to achieve specific functions. Pillared metal organic frameworks are a class of MOFs composed of inorganic secondary building units (SBUs) and two sets of organic linkers, generally oxygen- and nitrogen-donor ligands. Typically, in the structure of pillared MOFs, the oxygen-donor struts link the metal clusters into a two-dimensional (2D) sheet and the N-donor struts pillar the sheets to generate a three-dimensional (3D) framework. Thus, the construction of MOFs by utilizing two sets of organic linkers could provide an extra possibility for further tuning of MOF’s pore walls. A variety of functional groups including imine, amide and heterocycles were successfully incorporated into bidentate pillar ligand skeleton. Interestingly, by using pillaring linkers with different length, a wide diversity of metal-organic frameworks with tunable pore dimensions and topologies can be obtained. In this book, we introduce pillared metal organic frameworks with their properties and applications.
