metal organicframeworks (MOFs) viapostsynthetic linker exchange. Sequential and orthogonal click reactions could be performed on these modified MOFs by incubating the crystals with small molecule substrates bearing azide or acetylene groups in the presence of a copper catalyst. 1H NMR of digested MOF samples showed that up to 50% of the incorporated linkers could be converted to their “clicked” triazole

Herein we report a new second-order coordinate-covalent programming strategy for metal–organicframeworksynthesis. We show controlled heterofunctional copolymerisation turns on ‘in lattice’ linking to deliver highly porous frameworks in a single step process.

Strain-promoted "click" chemistry is used to post synthetically modify the pore walls of azide-functionalized mesoporous bio-MOE-100 (N-3-bio-MOE-100). The reactions proceed in high yield and produce no byproduct. This new method was used to introduce various functional groups into the MOF mesopores, including succinimidyl ester bioconjugation moieties that allow for straightforward coupling of biomolecules to the pore walls.
