A 12-connected fcu metal–organic framework (MOF), MMPF-3, has been prepared using a CoII metalloporphyrin. MMPF-3 is comprised of the same polyhedral supermolecular building blocks as the prototypal fcu-MOF, fcu-MOF-1, and its nanoscale cavities feature 18 catalytically active cobalt centers. The high density (ca. 5 cobalt sites/nm3) affords MMPF-3 superior performance in catalytic epoxidation of trans-stilbene compared to other MOFs.
