A zirconium-based metal–organic framework, an effective heterogeneous catalyst, has been developed for the Friedel–Crafts benzoylation of aromatic compounds under microwave irradiation. Constructed by a Zr(IV) cluster and a linker 1,4-bis(2-[4-carboxyphenyl]ethynyl)benzene (H2CPEB), the MOF, possessing large pores and high chemical stability, was appropriate for the enhancement of Lewis acid activity
