Metal organic frameworks (MOFs) are formed by central metal atoms surrounded by organic ligands, very much like metal complexes. Multidental ligands lead to a coupling of two or more metal atoms via bridging ligands, forming three dimensional networks.
Pseudo binary and multinary systems of metals and ligands have established a simple building block method of generating MOFs and thus forming an efficient base for specific modification of physical and chemical properties of MOFs.
Consecutively, this has lead to an increasing importance of MOFs in material and applied sciences. Especially the properties of porous networks and their capabilities for gas storage with hydrogen in particular has raised interests for applications in fuel cells and the general increasement of gas storage in high pressure containers, making porous MOFs an economically focus for the replacement of fossile fuel powered engines. Other fields such as heterogenous catalysis as well as gas filtration and gas seperation have made these compounds highly interesting representatives of a fast growing area of solid state chemistry.
Our workgroup has successfully synthesized different porous and luminescent MOFs based on metal nitrogen coordination ranging from rare earth via non-noble main group to 3d-transition metals, opening a new and interesting fast growing area of hybrid materials.
