Metalloporphyrin (MnCl)-Cl-III-5,10,15,20-tetrakis(3,5-biscarboxylphenyl)porphyrin, having eight carboxylate groups in multiple coordination modes, connects with paddle-wheel Zn-2(COO)(4) units for the construction of an interesting porous porphyrinic framework that demonstrates high efficiency and stability upon epoxidation of olefins with excellent substrate size selectivity.
