“…Figure S12 shows the electrostatic potential (ESP) mapping of each monomer and guest molecule by simulating the changes in binding sites and binding forces of C 7 H 8 or CH 2 O with different HCPs . The value of ESP followed the color order of red < orange < yellow < green < blue, where the red region showed the highest electron density . From Ben to BA and then to BDM molecules, the electron density of the Ben ring decreased gradually, continuously enhancing the π–π conjugation of Ben-SHCP, BA–DHCP, and BDM-DHCP toward C 7 H 8 molecules. , Besides, the increasing number of hydroxyl groups of the monomer also made the OH−π and O–H···O interaction of these samples to C 7 H 8 and CH 2 O molecules enhanced. , After partial substitution of Py blocks, new stronger N–H···O interaction appeared, again enhancing the binding force of N 0.1 /BDM-FDHCP to CH 2 O molecules .…”

High-capacity adsorption and removal of complex volatile organic compounds (VOCs) from real-world environments is a tough challenge for researchers. Herein, a swellable array adsorption strategy was proposed to realize the synergistic adsorption of toluene and formaldehyde on the flexible double hypercross-linked polymers (FD-HCPs). FD-HCPs exhibited multiple adsorption sites awarded by a hydrophobic benzene ring/pyrrole ring and a hydrophilic hydroxyl structural unit. The array benzene ring, hydroxyl, and pyrrole N sites in FD-HCPs effectively captured toluene and formaldehyde molecules through π–π conjugation and electrostatic interaction and weakened their mutual competitive adsorption. Interestingly, the strong binding force of toluene molecules to the skeleton deformed the pore structure of FD-HCPs and generated new adsorption microenvironments for the other adsorbate. This behavior significantly improved the adsorption capacity of FD-HCPs for toluene and formaldehyde by 20% under multiple VOCs. Moreover, the pyrrole group in FD-HCPs greatly hindered H2O molecule diffusion in the pore, thus efficiently weakening the competitive adsorption of H2O toward VOCs. These fascinating properties enabled FD-HCPs to achieve synergistic adsorption for multicomponent VOC vapor under a highly humid environment and overcame single-species VOC adsorption properties on state-of-the-art porous adsorbents. This work provides the practical feasibility of synergistic adsorption to remove complex VOCs in real-world environments.

“…Compared with traditional iron-containing nanoparticles, we synthesized the Shik-Fe NPs by a convenient, environmentally friendly, and efficient method. Moreover, both Gram-negative and Gram-positive bacteria could adsorb Fe (III) and rapidly reduce Fe (III) to Fe (II), resulting in the formation of hydroxyl radicals to enhance bacteria-killing efficacy via a Fenton reaction . Deduced from these results, Shik can possibly combine with other transition group metal ions (such as silver, copper, and zinc), metal oxides, or photocatalytic materials (e.g., TiO 2 and ZrO 2 ) to explore the combinational antibacterial activity in the future.…”

Shikonin (Shik), a natural pigment, has received growing interest in various biomedical fields due to its anti-inflammatory, antitumor, antimicrobial, and antioxidant ability. However, some inherent characteristics of Shik, such as its virulence, low bioavailability, and poor solubility, have limited its biomedical applicability. Here, we reported a facile synthetic method to produce the Shik-iron (III) nanoparticles (Shik-Fe NPs), which could overcome these limitations of Shik. The synthesized Shik-Fe NPs possessed a uniform size range of 110 ± 10 nm, negative surface charges, good water dispersity, and high safety. Iron distributed uniformly inside Shik-Fe NPs, and iron constituted 20% of total mass in PEGylated Shik-Fe NPs. When interacting with activated macrophages, Shik-Fe NPs significantly reduced the level of cellular inflammatory factors, for example, iNOS, IL-1β, and TNF-α. Furthermore, the Shik-Fe NPs demonstrated synergistic anti-inflammation and anti-bacterial properties in vivo, since they could release Fe3+ and Shik to eradicate bacteria (Staphylococcus aureus and P. aeruginosa were used as model microbes here) during wound infections and provide full recovery for scald wounds. Collectively, the study established a dual-functional Shik-derived nanoplatform, which could be useful for the treatment of various inflammation-involved diseases.

Recent advances in ordered porous materials, including metal‐organic (MOF) and covalent organic frameworks (COF), are set to revolutionize the strategies used for wastewater treatment. This is attributed to the large surface area, high crystallinity, structural tunability, thermal and chemical stability, and well‐defined structures of MOF and COF. Despite the distinctive properties exhibited by the single system (either MOF or COF), the combination of COF and MOF, as a hybrid construct, offers a remarkable opportunity to achieve superior functionality and performance. The favorable features of COF–MOF hybrids in different wastewater treatment sectors have opened new venues for effective environmental remediation. This review presents the state‐of‐the‐art design, synthesis, and application of COF–MOF hybrids. The synthesis principles, including MOF‐first, COF‐first, and post‐synthetic linkage of pre‐synthesized COFs and MOFs are summarized. The potential of these novel materials is evaluated by considering contaminant sensing, adsorptive removal, and catalytic photodegradation.The conclusion is drawn by assessing the existing hurdles and potential opportunities in the development of COF‐MOF hybrids as an innovative yet viable approach for addressing wastewater treatment.
