摘要：

Three isomorphous porous metal-organic frameworks (MOFs; PCN-9 (Co/Fe/Mn)) with entatic metal centers have been constructed on the basis of the trigonal planar H(3)TATB ligand and a novel square-planar secondary building unit. N-2 adsorption isotherms at 77 K confirmed the permanent porosities of the three porous MOFs. Variable-temperature adsorption measurements of H-2 revealed that the H-2 affinities of the three porous MOFs are related to the nature of entatic metal centers, which reversely affect their H-2 uptake capacities.
