A Series of Highly Stable Mesoporous Metalloporphyrin Fe-MOFs

A series of mesoporous metalloporphyrin Fe-MOFs, namely PCN-600­(M) (M = Mn, Fe, Co, Ni, Cu), have been synthesized using the preassembled [Fe3O­(OOCCH3)6] building block. PCN-600 exhibits a one-dimensional channel as large as 3.1 nm and the highest experimental pore volume of 1.80 cm3g–1 among all the reported porphyrinic MOFs. It also shows very high stability in aqueous solutions with pH values ranging from 2–11 and is to our knowledge the only mesoporous porphyrinic MOF stable under basic aqueous conditions. PCN-600­(Fe) has been demonstrated as an effective peroxidase mimic to catalyze the co-oxidation reaction.
