摘要
Post-synthetic modifications(PSM)have drawn great attention as a vigoroso tool to tune or enhance the performance of metal-organic frameworks(MOFs).However,the current PSM method usually have to sacrifice the porosity of MOFs to enrich their functionality,such as pore space partition(PSP)and postsynthetic elimination and insertion(PSE&I),causing a trade-off in this aspect.To address this issue,we herein propose a new PSM strategy of using the size-matching ligands as the bolts to lock MOFs'pores,which could be anchored onto open metal sites(OMSs)after guest loading through a stepwise manipulation.As a result,the loaded cargoes undergo a controlled releasing process with respect to different bolt ligands.Our proposed strategy provides a promising way to balance the functionality and porosity of MOFs.
