Abstract
AbstractPostsynthetic modification (PSM) of metal–organic frameworks (MOFs) provides access to functional materials and advanced porous solid engineering. Herein, we report the reversible PSM of a multivariate isoreticular MOF by applying dynamic furan‐maleimide Diels–Alder (DA) chemistry. The key step involves incorporating a furan group into the MOF via “click” PSM, which can then undergo repeated cycles of modification and de‐modification with maleimides. The structural integrity, crystallinity, and porosity of the furan‐appended MOF remained intact even after three consecutive PSM/de‐modification cycles using three different functionalized maleimides.
