1,3,5-Tris(4-carboxyphenyl)benzene 

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.^1,2,3 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

Sigma-Aldrich offers a variety of molecules that can serve as linkers for Metal Organic Frame Works. To see our current offerings in the area of Materials for Hydrogen Storage Applications, visit www.sigma-aldrich.com/hydrogen.
