Porous Organic Molecular Frameworks with Extrinsic Porosity: A Platform for Carbon Storage and Separation

The assembly of porous organic molecular frameworks (POMFs), which typically evidence common feasibility and compatibility, purification, and regeneration at practical conditions, remains a strategic challenge in modern materials science and is crucial for their favorable applications in biological, medical, and environmental realms. However, instructive knowledge of well-organized POMF assembly by supramolecular interactions is, in general, ambiguous to date. Nevertheless, a significant advance in controlled POMF assembly has been recently achieved. This Minireview highlights these approaches, with a particular focus on the design of molecular constituents and assembly strategies. We also look beyond the field of solid-state POMF materials into the assembly and recognition in solution, thus covering recent advances in POMFs based on material design and applications in carbon storage and separation.
