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.1-3
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.3
1,3,5-Tris(4-carboxyphenyl)benzene, Product No. 686859
Dr. Channing Ahn of the California Institute of Technology wrote to us about BTB 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!" |
