Metal−organic frameworks (MOFs) with large pore size and pore volume are highly desired because of their great potential in adsorption and catalysis. However, it is still very challenging to construct MOFs with tunable pore apertures, high crystallinity and high stability. Recently, our group reports a powerful method, linker labilization, to produce hierarchical porous structure with precisely controllable pore size, which takes advantage of weak points inside frameworks. Meanwhile, acid sensitive or water sensitive metal carboxylates bonds are very common in MOF chemistry, especially in the early stage of MOF development. Herein, we show that those weak coordinate bonds could be utilized as weak points to create mesopores inside a series of ultrastable multivariate MOFs. The hierarchically porous MOFs show enhanced guest adsorption and catalytic performances.
