We report the synthesis of uniform oligomeric polyMOF ligands with alkyne end groups via an iterative exponential growth (IEG) strategy. These ligands were used to prepare a diblock copolymer via copper-catalyzed azide–alkyne cycloaddition “click” chemistry with azide-terminated polystyrene (PS). In the presence of Zn ions, this novel block copolymer forms a “block co-polyMOF” (BCPMOF) comprised of crystalline polyMOF domains embedded in an amorphous PS matrix. BCPMOFs represent a new type of hybrid polyMOF–polymer material.
