Abstract

Quick on the uptake: The metal–organic framework Mg-MOF-C30 (see picture) contains Mg4O(CO2)6 building units (pink) and aromatic organic linkers containing 30 carbon atoms (teal). This material leads to 8.08 wt % H2 uptake at 77 K and 20 bar, the highest among investigated MOF structures.
