Summary: This article presents a method for synthesizing ladder polymers with sp3 backbones using photoredox catalysis. By designing specific monomers, ladder polymers with high molecular weights can be synthesized under mild reaction conditions, and these products can also be used as macromonomers to form ladder bottlebrush polymers.

Summary: Polyoxometalates (POMs) are versatile materials for chemical catalysis due to their tunable acidity and rich redox properties. In this study, a pure inorganic Keggin-type POM was anchored to a polymer support to fabricate composite materials. The composite fibers maintained the catalytic activity of the POM and showed potential for use in protective equipment.

Summary: Removal of dyes from industrial effluents is a challenging task, and there is a high demand for cost-effective methods and materials with high dye removal efficacy. Adsorption, nanofiltration, and photocatalytic degradation are the three major techniques that have been studied for dye removal. Polymer of intrinsic microporosity (PIMs) has shown promise for use in these techniques, due to its microporous structure, solution processibility, high chemical stability, and tunability through synthesis and postmodification. Although the number of reports on dye removal using PIMs is limited, some materials have demonstrated comparable dye separation properties to activated carbon, a state-of-the-art material. This highlight article summarizes the progress in PIMs and PIM-based composite materials for dye removal in the past decade, and discusses the challenges and key parameters for improving their dye removal properties.

Summary: HCMPS has attracted increasing attention due to its advantages such as diverse preparation methods, easy functionalization, large specific surface area, low cost reagents, mild reaction conditions, high chemical and thermal stability, etc. With the reasonable selection of polystyrene precursors, appropriate length crosslinkers, and optimal reaction conditions, advanced hypercrosslinked polymers with controllable porous topology can be obtained. This review systematically summarizes the fundamentals and synthetic strategies of HCMPS materials, outlines their recent advances in various applications, and discusses the state-of-the-art developments, opportunities, challenges, and perspectives.

Summary: A simple methyl substitution on the structural building blocks of a PIM can alter its chain stacking behavior. Nitrogen adsorption and enhanced gas permeability demonstrated the increased intrinsic microporous of the spirodifluoranthene-based PIMs. The series of polymers exhibited excellent gas separation performances, showing great potential in separation areas for CO2 capture and storage, natural gas and biogas upgrading.

Summary: In this study, four freestanding conjugated microporous polymer membranes were fabricated and their performance for organic solvent nanofiltration was evaluated. The results showed that the nanofiltration performance of the membranes was proportional to the pore size, indicating that the molecular sieving properties of the membranes could be controlled by pore size. All the membranes demonstrated long-term stability.

Summary: The adsorption and transport of molecules or ions in microporous materials provide unique properties. Confined polymers with special characteristics are being applied in advanced technologies. Amorphous microporous polymers with weak intermolecular bond strength, low long-range order, and large free-volume elements have potential in membrane separations and electrochemistry, but their design and synthesis remain challenging. This review focuses on the synthetic strategies of solution-processable amorphous microporous organic polymers and their characteristics. It also discusses the application of membranes derived from these polymers, computational tools for materials design, on-polymer modification methodology, and molecular transport/ion in sub-1-nm space.

Summary: This study investigates the removal of TCAs from wastewater using four polymeric networks based on triptycene and triphenylbenzene. The results show that sulfonic acid modified polymers tolerate higher concentrations of TCAs and follow pseudosecond-order kinetics and Langmuir isotherm models. The presence of coexisting ions affects the adsorption affinities, with a greater decrease observed using hydrocarbon-based polymers. Additionally, the study proposes a potential mechanistic pathway for the adsorption of these pharmaceuticals by the polymers.

Summary: A highly efficient approach for constructing target-specific conjugated microporous polymers (CMPs) is developed by screening feasible polymerization pathways. The obtained CMPs can achieve a high SO2/CO2 selectivity of 113 and a moderate Q(st) of 30 kJ mol(-1) for feasible regeneration through optimized Buchwald-Hartwig amination. Continuous breakthrough tests demonstrate the potential of CMPs for practical SO2/CO2 separation, and in situ Fourier transform infrared spectroscopy and grand canonical Monte Carlo simulation confirm the consistency between SO2 binding sites and screening results, providing solid feasibility for future synthesis of task-specific CMPs.
