Description
| Frequently Asked Questions | Live Chat and Frequently Asked Questions are available for this Product. |
| 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.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 |
| Linkage | 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. |
