“…The formation of the gradient structure can be interpreted as follows. First, the CC3 nanocrystals can be stabilized in the casting solution by the PIL chain to avoid aggregation [21c] . Then, during the evaporation process, these nanocrystals tend to segregate to the liquid‐air interface spontaneously.…”

The effective capture of iodine with high volatility and poisonousness is significant for reprocessing the spent nuclear fuel. In this article, we report a hierarchically porous poly(ionic liquid)-organic cage composite membrane (PIL@CC3) possessing a gradient content distribution of CC3 cage crystals throughout the membrane to capture iodine vapor. The introduction of microporous CC3 can significantly enhance the uptake capacity of iodine up to 980 mg g À 1 , which is superior to that of a pristine PIL membrane carrying large meso-and macropores (99 mg g À 1 ), and CC3 crystalline powder (662 mg g À 1 ). Such enhanced performance benefits from the micro-meso-macroporous structure of the PIL@CC3 membrane in which the large meso-and macropores facilitate the mass transfer of iodine molecules from the external environment into the surface of the CC3 crystal, followed by diffusion of iodine molecules from the CC3 surface into the interior and exterior pores of the CC3 crystal. In addition, the asymmetric distribution of CC3 crystals across the PIL@CC3 membrane also displays its advantage in intercepting trace iodine, revealing its great potential for practical application. This study provides an idea for constructing hierarchically porous membrane composites for the removal of toxic vapors.

“…The preparation of rGO/PIL nanocomposite films is schematically illustrated in Figure 1. The monomer1-benzyl-3vinylimidazolium chloride, termed IL, carrying simultaneously an imidazolium and a phenyl functionality was synthesized through a one-step quaternization reaction of 1-vinyl imidazole with benzyl chloride; IL was then radically polymerized (Figure 1) to poly(1-benzyl-3-vinylimidazolium chloride), abbreviated here as PIL (Men et al, 2013;Grygiel et al, 2015;Shao et al, 2020;Wang et al, 2020;Zhang et al, 2020). Its chemical structure and macromolecular features were characterized and confirmed by proton nuclear magnetic resonance ( 1 H NMR) spectroscopy and gel permeation chromatography (GPC), respectively (Supplementary Figures 1, 2).…”

Graphene and its derivatives are a classical group of two-dimensional (2D) building blocks possessing excellent mechanical and/or electrical properties in favor of preparing flexible electronic devices. Natural materials, such as nacre, provide inspiration and an exciting guideline for assembling 2D nanosheets into functional nanocomposites. In this context, despite recent advance, methods to assemble graphene-derived nanosheets into nanocomposites with the integrated enhancement of mechanical properties and electrical conductivity are eagerly pursued. Here, a rational design has been proposed and demonstrated, which utilizes synergistic supramolecular interactions between a polymeric additive and reduced graphene-oxide nanosheets to fabricate exceptional, integrated, strong, and tough nanocomposite films with high electrical conductivity. Such materials can be applied in areas such as, aerospace, artificial muscle, tissue engineering, and flexible electronics.

“…homogenized the heterogeneous Rh‐MCs (average size: 1.1 nm) in solution with the soluble cage (CC3R) as the support, where hydrogen could be rapidly released with a much higher efficiency of 215.3 mol of H 2 per mol of Rh per min than that in heterogeneous condition [72] . In another work, our group employed 1,2,4‐triazolium poly(ionic liquid)s (PILs) as a universal additive to accelerate the growth rate of CC3R in initial synthetic process [73] . PILs are well‐known as surface‐active polymers toward different substances through Coulombic interaction, cation‐π interaction, van der Waals' force, or other charge‐polarized interactions [74,75] .…”

Metal clusters (MCs) with dimensions between a single metal atom and nanoparticles of >2 nm usually possess distinct geometric and electronic structures, and their outstanding performance in catalysis applications have underpinned a broad research interest. However, smaller‐sized MCs are easily deactivated by migration coalescence during the catalysis process because of their high surface energy. Therefore, the search of an appropriate stabilizer for MCs is urgently demanded. In recent years, porous organic polymers (POPs) and organic molecular cages (OMCs), as emerging functional materials, have attracted significant attention. Benefiting from the spatial confinement, encapsulating MCs into these porous organic materials is a promising approach to guarantee the uniform size distribution and stability. In this review, we aim to provide a comprehensive summary of the recent progress in the synthetic strategies and catalysis applications of the encapsulated MCs, and seek to uncover promising ideas that can stimulate future developments at both the fundamental and applied levels.
