Metal Organic Frameworks (MOFs) Biphenylpyridine Ligand

A rigid linear ligand linker for MOFs in applications of methane storage

4'-(Pyridin-4-yl)-[1,1'-biphenyl]-4-carboxylic acid (HPBPC), CAS number 1393711-96-0, has a rigid linear structure of biphenylpyridine with a carboxylic acid at the end of benzene rings.

MOF NiL2 (L=4-(4-pyridyl)-biphenyl-4-carboxylic acid), shows a dynamic feature of diamondoid topology switches between closed non-porous and several open porous phases at specific CO2 and CH4 pressures. Metal doping of the MOF with cobalt ions enables control over the gate opening between non-porous and porous phases. By adjusting the ratio of Ni/Co, methane-induced phase transformations can be fine-tuned to enhance methane working capacity. The optimal working capacity from 5 to 35 bar at 298 K (153 cm3 cm−3) was found for Ni0.89Co0.11L2 (X-dia-1- Ni0.89Co0.11), which is greater than that of benchmark rigid MOFs.
