“…As for chiral cages, Cui's group constructed chiral Pd cages functionalized with crown ether and methoxymethyl groups in the inner surfaces. 56 Chiral hosts encapsulated anionic achiral BODIPY dyes to form stable host-guest systems via cationanion interactions, host-guest interactions and metal-coordination. The host-guest composites manipulated CPL in both solid and solution states with maximum |g lum | values of 2.4 × 10 −2 .…”

“…9 – 11 ). Compared with traditional metal-organic cages with a single cavity 32 – 34 , the Al 24 cage, therefore, has a ‘two-tier’ cavity arrangement, which combines the characteristics of an inorganic metal cage with that of a calixarene, and possesses inorganic hydrophilic and organic hydrophobic cavities (Supplementary Movie 2 ).

In this paper, we report a unique type of core-shell crystalline material that combines an inorganic zeolitic cage structure with a macrocyclic host arrangement and that can remove trace levels of iodine from water effectively. These unique assemblies are made up of an inorganic Archimedean truncatedhexahedron (tcu) polyhedron in the kernel which possesses six calixarene-like shell cavities. The cages have good adaptability to guests and can be assembled into a series of supramolecular structures in the crystalline state with different lattice pore shapes. Due to the unique core-shell porous structures, the compounds are not only stable in organic solvents but also in water. The characteristics of the cages enable rapid iodine capture from low concentration aqueous I2/KI solutions (down to 4 ppm concentration). We have studied the detailed process and mechanism of iodine capture and aggregation at the molecular level. The facile synthesis, considerable adsorption capacity, recyclability, and β- and γ-radiation resistance of the cages should make these materials suitable for the extraction of iodine from aqueous effluent streams (most obviously, radioactive iodide produced by atomic power generation).
“…It's known that introducing achiral guest emitters into host chiral matrices could endow achiral emitters with CPL activity via noncovalent interaction or a chiral confined microenvironment. 61,62 On the other hand, UV and NIR light-triggered dual-mode photoluminescence in chiral MOFs has rarely been reported, which has potential application in multi-dimension anticounterfeiting. NIR lights possess advantages such as low interference, high penetration, and precise spatial distribution.…”
