摘　　要：Cycloaddition of CO_(2) with aziridines is an important reaction to obtain high-value products.Porous MOFs can catalyze this reaction,but co-catalysts are still necessary to improve the catalytic performance.Such a reaction catalyzed by MOFs-based materials without co-catalyst has not been reported hitherto.Herein,a porous and stable three-dimensional(3D)framework{[Ni(DCTP)]·6.5DMF}_(n)(1)with a large Langmuir surface area of 3,789 m^(2)/g was synthesized,which displayed high I2 adsorption ability up to 731.0 mg/g and could release it reversibly.Additionally,it exhibited a high CO_(2) adsorption capacity of 104.0 cm^(3)/g at 273 K.The investigation results revealed 1 could effectively catalyze the cycloaddition of CO_(2) and aziridines in the absence of additional co-catalyst,and it could maintain the catalytic activity after five cycles.Furthermore,1 also exhibited high catalytic activity for the gram-scale experiment.Importantly,it is the first MOF material as a heterogeneous catalyst for the conversion of CO_(2) and aziridines without co-catalyst.
