Heterogeneous catalysis is one of the promising applications for metal-organic frameworks (MOFs) materials because of their high porosity, large surface areas and their flexible tailoring. An attractive approach to design MOFs-based catalysts is to heterogenize them by employing known homogeneous molecular catalysts as struts. In view of the enormous utility as active sites in metallo-enzymes, metalloporphyrin is obvious candidates for incorporation into MOFs as catalytically functional struts. Many efficient strategies have been established for the rational design and synthesis of catalytically functional porphyrinic MOFs. This review is aimed to summarize recent progress on porphyrinic MOFs, including new synthesis strategies and applications in catalysis. The development trends of porphyrinic MOFs are also prospected.
