Abstract

Open and close: Inspired by close-packing of spheres, to strengthen the framework-H₂ interaction in MOFs (metal-organic frameworks), a strategy is devised to increase the number of nearest neighboring open metal sites of each H₂-hosting cage, and to align the open metal sites toward the H₂ molecules. Two MOF polymorphs were made, one exhibiting a record high hydrogen uptake of 3.0 wt% at 1 bar and 77 K. (Chemical Equation Presented)
