Abstract Porous Organic Cages (POCs) have gathered a lot of attention in sorts fields. Previous studies often focused on the functionalization their intrinsic porosity, while utilization extrinsic porosity has been seldom reported. To date, rational construction functionalized POCs is serious challenge, which still relies trial and error. Inspired by hydrophobic proteins, contribution, POC (namely NKPOC‐DS) obtained with “intermolecular pocket” as constructed through assembly disulfide bonds groups, facilitating strong supramolecular interactions confirmed Electrostatic Potential (ESP) maps single‐crystal X‐ray diffraction analysis. Notably, NKPOC‐DS exhibits unique C 2 H 6 ‐selective “breathing behaviour” due to presence softness its does not extend other gases such 4 , CH CO N . Such specific recognition thus provides ability preferentially adsorb from /C mixture. The innovative approach biomimicry design functional new insights into manipulating packing cages, paving way for potential applications guest adsorption separations.

Abstract The capture of radioactive iodine species from nuclear waste is crucial for environmental protection and human health. Porous organic cages (POCs), an emerging porous material, have showed potential in adsorption due to the advantages tunable pores processibility. However, integrating multiple desirable characteristics into a single POC through bottom‐up assembly pre‐designed building blocks remains challenging. Post‐synthetic modification (PSM) offers alternative approach, enabling introduction various functions POC. Herein, viable highly efficient three‐step PSM strategy modify representative (CC3), presented. modified POC, OFT‐RCC3 6+ 6Br − , features charged confined space, electron‐rich heteroatom, halide ions, exhibiting significantly enhanced vapor uptake compared parental cage. universality has been verified by successfully modifying two other POCs. behaviors three cage adsorbents solvent aqueous solution also investigated, all which exhibited improved performance, especially comparison ionic direct protonation. This work provides effective POCs facilitate adsorption. More importantly, new enriches functional diversity POCs, potentially broadening their future applications.

In the realm of nanoscale materials design, achieving precise control over dimensions nanotubular architectures poses a substantial challenge. our ongoing pursuit, we have successfully engineered novel class single-molecule nanotubes─isoreticular covalent organic pillars (iCOPs)─by stacking formylated macrocycles through multiple dynamic imine bonds, guided by principles reticular chemistry. Our strategic selection rigid diamine linkers has facilitated synthesis diverse array iCOPs, each retaining homologous structure yet offering distinct cavity shapes influenced linker choice. Notably, three these iCOP variants feature continuous one-dimensional channels, exhibiting length-dependent host-guest interactions with α,ω-dibromoalkanes, and presenting critical guest alkyl chain length threshold for efficient encapsulation. This newfound capability not only provides platform tailoring structures precision, but also opens new avenues innovative applications in molecular recognition purification complex mixtures.
