Metal Organic Frameworks: The highly porous and versatile future material

Metal Organic Frameworks Metal organic framework (MOFs) are a class of porous crystalline materials composed of metal ions or metal-containing clusters coordinated to organic ligands. The large internal surface area of a MOF lends it well to storage of gases such as hydrogen, methane, or carbon dioxide. In addition, MOFs offer tunable pores, large surface areas, and excellent chemical and thermal stability. These promising properties have spurred intense research on MOFs for gas storage and separation, catalysis, drug delivery, sensing, and more. Porous Structure The high porosity or internal surface area of MOFs is one of their most advantageous properties. Metal Organic Framework crystals feature metal ion centers connected by organic linkers into two- or three-dimensional framework structures with nanometer-sized channels and cavities. Careful selection of the metal ions and organic ligands allows for systematic tuning of the pore size, functionality, and geometry. Measur...
