Metalloporphyrinic Framework Containing Multiple Pores for Highly Efficient and Selective Epoxidation

Metalloporphyrin MnIIICl-5,10,15,20-tetrakis­(3,5-biscarboxylphenyl)­porphyrin, having eight carboxylate groups in multiple coordination modes, connects with paddle-wheel Zn2(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.
