Hydrogen-bonded organic frameworks (HOFs), self-assembled from or metalated building blocks (also termed as tectons) by hydrogen bonding, π–π stacking, and other intermolecular interactions, have become an emerging class of multifunctional porous materials. So far, a library HOFs with high porosity has been synthesized based on versatile tectons supramolecular synthons. Benefiting the flexibility reversibility H-bonds, feature structural flexibility, mild synthetic reaction, excellent solution processability, facile healing, easy regeneration, good recyclability. However, flexible reversible nature H-bonds makes most suffer poor designability low framework stability. In this Outlook, we first describe development features summarize design principles strategies to enhance their Second, highlight state-of-the-art for diverse applications, including gas storage separation, heterogeneous catalysis, biological sensing, proton conduction, applications. Finally, current challenges future perspectives are discussed.

Abstract In the event of a public health crisis, highly effective and sustainable antimicrobial materials equipment will be urgently needed. Here, preparation is reported by electrospinning broad‐spectrum antibacterial nanofibers embedded in photoactive hydrogen‐bonded organic framework (HOF) rod‐like nanocrystals ≈60 nm length. The resulting HOF@PVDF‐HFP maintain excellent tensile breathability characteristics while shielding HOF against acid alkali corrosion. A series with different amounts types are prepared to optimize their efficiency singlet oxygen ( 1 O 2 ) generation. 0.5 wt.% HOF‐101‐F@PVDF‐HFP exhibit most efficient generation that enhanced factor almost when compared HOF‐101‐F microcrystalline powder. demonstrated effectively kill pathogens, including viruses, bacteria, fungi 30 min under ambient light conditions.

Abstract Hydrogen‐bonded organic frameworks (HOFs) are emerging porous materials that show high structural flexibility, mild synthetic conditions, good solution processability, easy healing and regeneration, recyclability. Although these properties give them many potential multifunctional applications, their unstable due to the presence of only weak reversible hydrogen bonds. In this work, development history synthesis methods HOFs reviewed, categorize design concepts strategies improve stability. More importantly, significant latest HOF‐related research for addressing energy environmental issues, work discusses advances in storage conversion, substance generation isolation, detection degradation transformation, biological applications. Furthermore, a discussion coupling orientation HOF cross‐cutting fields environment is presented first time. Finally, current challenges, opportunities, advance applications discussed.

The self-healing behavior has been extensively used in intelligent sensing systems capable of molecular recognition. However, most rigid crystalline frameworks, once collapsed under external stimuli like pressure, heat, or vacuum, could hardly recover to their phases ambient conditions. Here, we report the a new microporous hydrogen-bonded organic framework, FDU-HOF-3 (FDU = Fudan University), for ammonia (NH

Detecting CO2 in complex gas mixtures is challenging due to the presence of competitive gases ambient atmosphere. Photoelectrochemical (PEC) techniques offer a solution, but material selection and specificity remain limiting. Here, we constructed hydrogen-bonded organic framework based on porphyrin tecton decorated with diaminotriazine (DAT) moieties. The DAT moieties molecules not only facilitate formation complementary hydrogen bonds between tectons also function as recognition sites resulting porous HOF materials for selective adsorption . In addition, in-plane growth FDU-HOF-2 into anisotropic molecular sheets large areas up 23000 μm2 controllable thickness 0.298 2.407 μm were realized yields over 89 % by simple solution-processing method. can be directly grown deposited onto different substrates including silica, carbon, metal oxides self-assembly situ formic acid. As proof concept, screen-printing electrode was fabricate label-free photoelectrochemical sensor detection. Such signal-off PEC exhibits low detection limit (2.3 ppm), reusability (at least 30 cycles), long-term working stability days).

The integration of hydrogen-bonded organic frameworks (HOFs) into electronic devices holds great promise due to their high crystallinity, intrinsic porosity, and easy regeneration. However, despite potential, the utilization HOFs in remains largely unexplored, primarily challenges associated with fabricating high-quality films. Herein, a controlled synthesis HOF nanofilms smooth surface, good orientation is achieved using solution-processed approach. memristors exhibit outstanding bipolar switching performance low set voltage 0.86 V, excellent retention 1.64 × 104 s, operational endurance 60 cycles. Additionally, these robust display remarkable thermal stability, maintaining even at elevated temperatures up 200 °C. More strikingly, scratched films can be readily regenerated through simple solvent rinsing process, enabling reuse for fabrication new memristors, which difficult achieve traditional resistive materials. mechanism based on reversible formation annihilation conductive filaments revealed. This work provides novel invaluable insights that have significant impact advancing widespread adoption as active layers devices.
