• Preparation of porous materials from one‐dimensional polymers is challenging because the packing of polymer chains results in a dense, non‐porous arrangement. Herein, we demonstrate the remarkable adaptation of an amorphous, linear, non‐porous, flexible organic polymer into a three‐dimensional, highly porous, crystalline solid, as the organic component of a metal–organic framework (MOF). A polymer with aromatic dicarboxylic acids in the backbone functioned as a polymer ligand upon annealing with ZnII, generating a polymer–metal–organic framework (polyMOF). These materials break the dogma that MOFs must be prepared from small, rigid ligands. Similarly, polyMOFs contradict conventional polymer chemistry by demonstrating that linear and amorphous polymers can be readily coaxed into a highly crystalline, porous, three‐dimensional structure by coordination chemistry. A bottom‐up strategy is used to generate porosity from non‐porous, one‐dimensional, amorphous polymeric materials by their transformation into crystalline polyMOF materials. These materials harness the advantages of the porosity and crystallinity of MOFs along with certain attributes of the polymers, such as facile film formation and greater chemical stability.
