In reticular chemistry, molecular building blocks are designed to create crystalline open frameworks. A key principle of chemistry is that the most symmetrical networks likely outcomes reactions, particularly when highly involved. The strategy synthesizing low-dimensional aims reduce explicitly symmetry blocks. Here we report spontaneous formation hydrogen-bonded fibrous structures from trigonal prismatic blocks, which were form three-dimensional on account their structures. Utilizing different microscopic and spectroscopic techniques, identify at early stages assembly process in order understand growth mechanism. incorporated preferentially longitudinal direction, giving rise anisotropic porous organic nanotubes. Entropy-driven provides micrometer-scale unidirectional nanotubes with high porosity. By combining experimental evidence theoretical modeling, have obtained a deep understanding nucleation processes. Our findings offer fundamental insight into design tubular evolve further transverse directions provide extended higher-order [nano- microfibers], ultimately leading large-scale interconnected fiber-like twists turns. work paves way for innovative designs networks.

Abstract Perchlorate (ClO 4 − ) contamination in surface water is an escalating issue for drinking safety. Herein, imine‐linked covalent organic framework (COF) tuned by quaternary ammonium alkyls (R N + developed ClO adsorption. The hydrophobic and cationic COF adsorbent achieves a record‐breaking adsorption capacity of at 912.7 mg g −1 , demonstrating remarkable selectivity over other environmentally relevant anions exhibiting rapid kinetics. Furthermore, the maintains excellent recycling performance (removal efficiency ≥ 80% after 10 cycles) using tetrachloroferrate regeneration. In dynamic flow‐through experiments with real samples, effectively treats ≈3200‐bed volumes feed streams (≈500 µg L ), enrichment factor 15.2. hydrophobicity identified as premise its interaction . Molecular simulations density functional theory calculations reveal that R anchored cores enriches via electrostatic attraction bonds unconventional hydrogen (C─H─O). These key insights pave way future design optimization adsorbents removing oxo‐anion from water, especially

Porous organic materials showcasing large framework dynamics present new paths for adsorption and separation with enhanced capacity selectivity beyond the size-sieving limits, which is attributed to their guest-responsive sorption behaviors. hydrogen-bonded crosslinked frameworks (HCOFs) are attractive remarkable ability undergo guest-triggered expansion contraction facilitated by flexible covalent crosslinkages. However, voids of HCOFs remain limited, restrains extent dynamics. In this work, we synthesized a series characterized unprecedented size capabilities induced solvents. These were constructed isoreticularly co-crystallizing two complementary sets hydrogen bonding building blocks generate porous molecular crystals, through thiol–ene/yne single-crystal-to-single-crystal transformations. The generated exhibit chemical durability, high crystallinity, extraordinary For instance, HCOF-104 crystals featuring pore diameter 13.6 Å expanded in DMF 300 ± 10% original lengths within just 1 min. This allows adsorb guest molecules that significantly larger than sizes crystalline states. Through methanol-induced contraction, these guests encapsulated fast-contracted HCOFs. advancements pave way methods encapsulating targeted delivery.

A simple, readily-prepared precipitant (1.Cl2) precipitates oxalate or terephthalate from water with very high efficacy, removing these anions at sub-millimolar concentrations using only one equivalent of precipitant. simple aqueous base/acid cycle can be used to regenerate 1.Cl2 after use. The resulting precipitates, 1.oxalate and 1.terephthalate, are anhydrous closely-packed, each anion receiving eight charge-assisted hydrogen bonds amidinium N–H donors. Precipitation occurs much lower than other dicarboxylates, direct competition experiments the biologically/environmentally relevant divalent CO32–, HPO42– SO42– reveal selectivity for over competitors.
