Hierarchically porous materials play an important role in facilitating mass transport and improving efficiency of adsorption and separation processes. In this paper, a new strategy is proposed to realize a hierarchically porous metal-organic framework （[Cu2（OH）（L）]＇（DMF）0.8 （FJU-11, H3L=3,5-（4-carboxybenzyloxy）benzoic acid, DMF= N,N-dimethylformamide） via using semi-rigid multi-carboxylic acids. Interestingly, FJU-11 possesses the large adsorption capacities and small isosteric heats toward CO2. The column breakthrough experiment for FJU-11 highlights its potential application in the separation of the flue gas.
