Summary: To overcome the limitations of supramolecular organic cages, a nitrogen-rich organic cage is linked into framework systems, resulting in the successful synthesis of four isoreticular covalent organic frameworks. These frameworks exhibit high-quality crystalline structures and enhanced iodine adsorption capacities. The strong interactions between the nitrogen-rich sites and the adsorbed iodine species are revealed. This work demonstrates the potential of utilizing reticular chemistry to exploit the properties of supramolecular organic cages for targeted applications.

Summary: Porous organic polymers (POPs) are porous materials composed of light elements such as C, H, N, and O. Their benign characters, including large surface area, good physical and chemical stability, well-defined chemical composition, wide ranges of monomer selection, and strong designability, have made POPs one of the frontiers in materials research. In this review, we discussed the design and synthesis of various POP materials that mainly led by Chinese scientists, and sorted out their main applications in adsorption, separation, catalysis, and electrochemistry fields.

Summary: Porous organic cages (POCs) are a class of organic materials with intrinsic porosity. Post-synthetic modification (PSM) has emerged as a highly viable strategy for broadening the functions and applications of POCs, leading to improved stability, tunable porosity, and selective guest binding. This approach allows for the realization of intricate structures and unique gas adsorption selectivity that cannot be achieved through traditional predesign methods.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
