Abstract
Fabricating flexible membranes from porous metal–organic polyhedrons (MOPs) is in high demand for their industrial applications, yet it remains challenging. In the present study, we have successfully fabricated a soft self-healable 2D film with an elastic modulus of 10 MPa composed of 1-D supramolecular polymers by using MOPs grafted by 24 polymeric arms as monomers. The key to our success lies in implementing a phase-separation technique to generate a frustrated conformation for ligands at equatorial positions of MOPs, for 24 polymeric ligands. This frustration enables selective ligand exchange reactions, thus facilitating the supramolecular polymerization of MOPs with accurate pore structure in a controlled manner. In the meantime, the degree of supramolecular polymerization could be tailored by carefully tuning the size of the linkers.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
