A nanotubular metal-organic framework with permanent porosity: structure analysis and gas sorption studies

A nanotubular metal-organic framework, PCN-19, was constructed based on a mu(3)-oxo-trinickel basic carboxylate secondary building unit (SBU) and the 9,10-anthracenedi-carboxylate ligand; its permanent porosity was confirmed by N-2 adsorption isotherms, and its H-2 storage performances were evaluated under both low and high pressures at 77 K.
