Metal-Organic Frame Works (MOFs) for Smart Applications

Metal-organic framework (MOF) is a class of materials, which is formed by combining metal/inorganic and organic linkers, resulting in the formation of a framework with high surface area and permanent porosity. The freedom to vary inorganic and organic linkers stimulated the synthesis of thousands of MOF structures, for their utility in various applications. The presence of high porosity, high surface area and high free volume made these materials a perfect choice among the class of solid adsorbents. The metal nodes, tunable pore, versatile structure and functionalized surface allow various types of chemical interactions, viz. electrostatic interactions, π complexation, H-bonding, coordination bonding, van der Waals interactions, hydrophobic/hydrophilic interactions. All these features made MOF a customizable material to be utilized for targeted applications. This chapter involves a discussion about the usage of versatile MOFs in smart applications, such as gas storage, gas separation and drug delivery, along with a brief discussion about the synthesis of MOFs.
