1,3,5-Tris(4-carboxyphenyl)benzene: (NEW) Building Block for Metal Organic Frameworks

Dr. Channing Ahn of the California Institute of Technology kindly suggested that we make 1,3,5-tris(4-carboxyphenyl) benzene (BTB) — a building block for Metal Organic Frameworks (MOFs). MOFs are a class of 3D-microporous materials with potential applications in adsorption and separation technologies.1–3 BTB can be used as a linker to make MOFs with very high surface area, such as MOF-177: a hydrogen absorbing material with an extremely high storage capacity of 7.5% at 77K.3
