摘      要：The fabrication of hierarchically porous metal-organic frameworks(HP-MOFs)that combine tunable mesopore sizes with high stability is highly desired but remains a technical ***,a facile and versatile“rigid modular-assisted defect formationstrategy has been developed to transform microporous MOFs into their corresponding *** controlling the modulator dose and acid amount,the pore size and mesopore percentage can be finely *** on the hierarchical pores,the mass transfer of molecules with large sizes is significantly *** a result,the representative HP-UiO-66-NH_(2)-OTf,decorated with a trifluoromethanesulfonate(OTf)group to enhance Lewis acidity,exhibits excellent activity and selectivity in tandem catalysis,far superior to pristine UiO-66-NH_(2).This work provides a novel strategy to the general synthesis of stable HP-MOFs.
