<p>Metal-organic frameworks (MOFs) are porous coordination polymer containing bi-or polidentate organic linker coordinated with inorganic part, such as metal oxide cluster or metal cation as node which called as secondary building unit (SBU) to form infinite structure. Due to high porosity and surface area, good thermal stability as well as the availability of unsaturated metal center or the linker influence attracts the interaction with gases, thus MOFs have potential to be applied as hydrogen storage material.

The inherent porous nature and facile tunability of metal–organic frameworks (MOFs) make them ideal candidates for use in multiple fields. MOF hybrid materials are derived from existing MOFs hybridized with other materials or small molecules using a variety of techniques. This led to superior performance of the new materials by combining the advantages of MOF components and others. In this review, we discuss several hybridization methods for the preparation of various MOF hybrids with representative examples from the literature. These methods include covalent modifications, noncovalent modifications, and using MOFs as templates or precursors. We also review the applications of the MOF hybrids in the fields of catalysis, drug delivery, gas storage and separation, energy storage, sensing, and others.

Reticular chemistry, the linking of molecular building units by strong bonds to make crystalline, extended structures such as metal–organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), and covalent organic frameworks (COFs), is currently one of the most rapidly expanding fields of science. In this contribution, we outline the origins of the field; the key intellectual and practical contributions, which have led to this expansion; and the new directions reticular chemistry is taking that are changing the way we think about making new materials and the manner with which we incorporate chemical information within structures to reach additional levels of functionality. This progress is described in the larger context of chemistry and unexplored, yet important, aspects of this field are presented.

Clean Air

Addressing the three major stresses facing our planet, clean air, clean energy, and clean water, is within our reach. At present, new materials such as metal-organic frameworks and covalent organic frameworks, produced by reticular chemistry, are at the forefront of efforts to capture carbon dioxide from air and harvest water from air. We envision that the products of these two capture processes (carbon dioxide and water) can be fed into a conversion cycle in which they are used to produce fuels and chemicals via artificial photosynthesis. The use of air as a nonpolluting, cyclable, and sustainable resource for carbon and water can be powered by sunlight. We describe how the scientific basis for realizing this vision is either already achieved or being established, and that in the fullness of time this paradigm may lead to new global industries and a thriving “air economy.”

The use of predictable coordination geometries and the development of new ligands has allowed supramolecular chemists to design a plethora of new materials. Among these are metal-organic frameworks (MOFs), which are composed of ligands coordinating to metal atoms or clusters to generate a framework with potential porosity. MOFs exemplify supramolecular design strategy as their extended structure and tunable properties allow them to be applied for various applications.1 To date, many MOFs utilize carboxylates as the coordinating group since they have well studied coordination geometries and thus predictable framework topologies. Though there are examples of carboxylate-based MOFs possessing water stability, most do not possess this key feature, hindering their application in industrial settings. Phosphonate monoesters (PMEs) have been investigated as a means to impart water stability to a MOF by kinetically shielding the linker-metal bond with the ester moiety.2 Unfortunately, phosphonate monoesters have relatively unexplored coordination geometries, with most studies focusing on chlodronic acid and its derivatives, which do not typically form porous materials. In an attempt to establish building units based on PMEs, 1,4-benzenediphosphonate monoester ligands have been synthesized, coordinated to Cu(II), and characterized. It was found that while the methyl and ethyl analogues form similar 3-D structures with poor water stability,3 the isopropyl analogue forms a layered material possessing water stability. The isopropyl analogue contains chains of Cu-PME, with the isopropyl esters lying directly above and below the Cu atoms, kinetically shielding this bond from water. This water stable building unit was predicted to generate a porous framework with non-linear ligands. To test this hypothesis, 1,3,5-benzenetriphosphonate monoisopropyl ester was synthesized and coordinated to Cu(II). Unfortunately, no single crystal of sufficient quality has been produced, though a predicted and refined structure matches well to various characterization techniques. As predicted, this material is porous and does not degrade in harsh humid conditions (353K and 90% relative humidity).
