Open hollow dodecahedral cage clusters have long been a coveted target in synthetic chemistry, yet their creation poses immense challenges. Here we report two open lanthanide–aluminum (Ln–Al) heterometallic clusters, namely, [Ln210Al140(μ2-OH)210(μ3-OH)540(OAc)180(H2O)156](ClO4)120·(MeCN)x·(H2O)y, (Ln = Dy and x 27, y 300 for 1; Ln Y 28, 420 2). Remarkably, the 350 metal atoms 1 2 display Keplerate-type four-shell structure of truncated icosidodecahedron@dodecahedron@dodecahedron@icosidodecahedron. The diameter cationic cluster is approximately 5.0 nm, with an inner cavity about 2.8 nm window roughly 0.66 nm. boasts accessible void volume up to 15,000 Å3. Notably, these maintain stability water, icosidodecahedrons are first kind synthesized date. Given that Ln–Al has never reported before, this work represents member family cages.

We present the synthesis of two triazole-linked porous cage polymers (pCAGEs) using D3h symmetric shape-persistent organic cages different sizes as monomers. observed that expanding size monomer resulted in an improved surface area, pore volume, and iodine vapor uptake capacity up to 4.02 g g–1 at 75 °C under ambient pressure. Also, embedding molecular into pCAGEs boosted their adsorption performances compared discrete counterparts, model compounds (mCAGEs), due open channels, enabling efficient diffusion binding sites. The showed promising efficiencies from a concentrated KI/I2 aqueous solution with high 3.35 g–1. capacities differ solutions, which suggests tuning allows us not only control textural properties but also tailor water. Iodine mechanisms were investigated ex situ structural characterization techniques, revealing strong interactions adsorbed species nitrogen-rich groups phenyl rings pCAGEs. Notably, demonstrated remarkable regeneration reusability, maintaining 86% initial over five adsorption/desorption cycles, highlighting potential for practical applications. These findings contribute fundamental understanding structure–property relationship cage-based polymeric materials provide insights development high-performance adsorbents capture.

The simultaneous capture of radioactive molecular iodine (I2) and methyl iodide (CH3I) coexisting in the exhaust stream nuclear power plants has become an urgent challenging task. However, there are a few adsorbents that can be used to achieve this goal. Herein, three nitrogen-rich pillar[5]arene-based hyper-cross-linked polymers presented. Among these polymers, P[5]A-TPTA12, which was constructed with deca(diethylaminoethoxy)pillar[5]arene 2, 4, 6-tris(4-(bromomethyl)phenyl)-1, 3, 5-triazine, exhibited excellent uptake capacities for gas (4.83 g g–1) (1.08 under static sorption conditions. A great deal effective diverse desorption sites, including nucleophilic N aromatic rings, oxygen atoms, were responsible adsorption capacity. work presented not only important method removal contaminants but also remarkable employment macrocycle-based materials environmental remediation.
