Metal Organic Frameworks MOFs

Metal-organic frameworks (MOFs) are materials in which metal – to-organic ligand interactions yield porous coordination networks with record-setting surface areas surpassing activated carbons and zeolites. The applications of MOFs include storage and separations of gases, sensors, catalysis and others.1

MOFs are usually prepared under solvo- or hydrothermal conditions in pure N,N-diethylformamide or N,N-dimethylformamide, which slowly decompose upon heating and generate bases capable of deprotonating organic linker molecules. The latter react with metal salts and produce 3D meta-organic networks. A typical approach to MOF synthesis is depicted in
Figure 1.2

Metal salts, solvents and MOF linkers, suitable for the preparation of high performance MOF-1773, UMCM-1504, NOTT-1015 and many others, are listed in the table below.


Dr. Channing Ahn of California Institute of Technology wrote to us about BTB (Prod. No. 686859) purchased from Sigma-Aldrich:

We're very happy with the results so far. Looks like your linker works well and has certainly saved us a lot of trouble in not having to make it ourselves!
