Application
1,3,5-Tris(4-carboxyphenyl)benzene (BTB) is a building block for Metal Organic Frameworks (MOFs). MOFs are 3D-microporous materials with potential applications in gas adsorption and separation technologies. BTB has been recently used as a linker to make MOFs with extremely high surface area such as MOF-177 (~ 5000 m2/g), a hydrogen absorbing material with an extremely high hydrogen storage capacity of 7.5% at 77K.
1,3,5-Tris(4-carboxyphenyl)benzene (H3BTB) is a star-shaped two-dimensional molecule that forms a self-assembled monolayer (SAM) on a variety of substrates. It can be used as a tritopic bridging ligand that facilitates the functionalization of polyoxometalate-based metal organic frameworks (MOFs) for potential usage in gas storage, gas separation, and catalysis.[1][2]

Is a protocol available for using Product 686859, Benzoic acid, to produce Metal Organic Frameworks (MOFs) with high surface area?
1 answer-
Unfortunately, Sigma-Aldrich does not manufacture MOFs and do not have a protocol for using this material for a similar application. However, a synthesis method for preparing MOF-177 (a MOF with high surface area) can be obtained from the following reference: Chae, H. K.; Siberio-Perez, D. Y.; Kim, J.; Go, Y.-B.; Eddaoudi, M.; Matzger, A. J.; O’Keeffe, M.; Yaghi, O. M. Nature 2004, 427, 523-527. In addition to product #686859, Zinc (II) nitrate hexahydrate (e.g. product #96482) and N,N-Diethylformamide (e.g. product #186317) would be required to prepare the MOF in this reference.
