Summary: Access to the solution structures of nanocomposites of coordination nanocages (CNCs) via scattering and chromatography techniques has allowed researchers to resolve their mysterious solution dynamics for the first time. The exchange of macromolecules in the solution mixtures of CNC nanocomposites at high temperatures revises the understanding of their dynamics. The quantified solution dynamics of CNC nanocomposites show a typical logarithmic time dependence with the dissociation of surface macromolecules as the thermodynamically limiting step, suggesting strongly coupled and hierarchically constrained dynamics among the surface macromolecules.

Summary: Ligand functionalization allows for modification of the properties of coordination cages, but optimizing multiple properties can be challenging. Mixed-ligand cages can potentially address this issue by combining the benefits of various functional groups. Direct synthesis of mixed-ligand products is necessary for molybdenum(II) paddlewheel-based cages. Highly soluble, highly porous, and thermally stable cuboctahedral cages can be obtained using this strategy.

Summary: This passage discusses one way to embed the edge-graphs of Platonic polyhedra and explores their symmetries and their potential to be untangled. Symmetric tangled polyhedra can overlap with the vertices of Platonic polyhedra, but their helicity requires specific edge shapes. This research is important for understanding Platonic polyhedra and their topological properties.

Summary: In this study, a new type of photoresponsive metal-organic polyhedra (PMOP) with pendant azobenzene units was successfully synthesized and dispersed into a metal-organic framework (MOF), resulting in improved CO2 uptake and controllability. Visible light allows CO2 molecules to freely enter the nanospace of PMOP, while ultraviolet light prevents their entrance. Additionally, UV/visible light irradiation enables the reversible cis-/trans-isomerization of the azobenzene groups in PMOP. The adsorption variation of CO2 captured by the PMOP@MOF composite under light is 15.5%, significantly higher than that of bulk PMOP (5.9%). These findings provide insights into the potential of PMOPs and inspire the development of efficient strategies for controlling adsorption processes.

Summary: The study introduces a new synthetic approach called Clip-off Chemistry, which allows for selective bond breaking in reticular materials and is effective in reactions performed in solid or liquid phases. This method opens the door to the programmed disassembly of reticular materials, leading to the design and synthesis of new molecules and materials.

Summary: This paper describes the preparation of a new class of reactive porous solids through straightforward salt metathesis reactions. A porous solid is obtained by reacting the dimethylammonium salt of a magnesium-based porous coordination cage with the chloride salt of [(CrCl)-Cl-II(Me(4)cyclam)](+), with simultaneous removal of dimethylammonium chloride. The porous salt exhibits a Brunauer-Emmett-Teller (BET) surface area of 213 m(2) g(-1) and the chromium(II) cations in the structure are still accessible and reactive, as confirmed by UV-vis spectroscopy. The site-isolated reactive centers show enhanced stability and reactivity compared to dissolved ions.

Summary: The construction of hierarchically macro-micro-porous metal-organic frameworks with thin macroporous walls has been achieved using a microemulsion-guided assembly strategy. The resulting cerium-based MOFs exhibit highly accessible active sites and have potential applications in DNA scissoring-related biological processes.

Summary: Introducing functionalities into metal-organic cage complexes can provide distinctive properties and utilities, typically achieved by modifying organic linkers or introducing functional groups at metal sites. By replacing sulfates with phosphonate groups, functionalities can be installed within the cage cavities, highlighting the complex self-assembly process and molecular diversity accessible through endo functionalization.

Summary: The charge-driven self-assembly of cationic zirconium-based metal-organic polyhedra with polyoxometalates leads to porous crystalline salts, prepared by simple mixing of soluble precursors. The reactivity of immobilized POMs is significantly increased, as demonstrated by their rapid reduction by hydrazine vapors without compromising structural integrity.

Summary: Three cationic capsule-shaped Zr-based metal-organic polyhedra (MOPs) were successfully constructed, showing good CO2 adsorption uptake and ability to catalyze the cycloaddition reaction of CO2 with epoxides synergistically. This is the first report of using MOPs as catalysts for this reaction without the addition of a cocatalyst.

Summary: The formation of porous and non-porous polymorphs in different solvents is shown to depend on a solvophobic effect driven by dispersion interactions, with weak dispersion interaction facilitating porous packing. Dense packing is a universal tendency of organic molecules in the solid state, but a solvophobic approach allows for the successful synthesis of porous polymorphs.

Summary: This review article discusses the key developments that make the extension of Metal-organic polyhedra (MOPs) possible, highlighting the most remarkable examples of MOP-based soft materials and crystalline extended frameworks. The article also ventures to offer future perspectives on the exploitation of MOPs in fields that still remain ripe toward the use of such unorthodox molecular porous platforms.

Summary: In this study, a postmodification protocol was developed to attach a chiral cholesteryl pendant to metal-organic polyhedra (MOPs) through covalent conjugation, enabling the self-assembly of chiral superlattices. The postmodification process preserved the coordination cores and allowed for reaction-induced self-assembly in loosely packed nanosized columns. Solvent-processed bottom-up self-assembly in aqueous media resulted in twisted superlattices with a 5 nm lattice parameter. The intercholesteryl forces were found to play a crucial role in the rotation of nanosized MOPs and the transfer of chirality to the supramolecular scale. This work presents a novel approach to the rational design of chiroptical materials based on MOPs for potential applications in enantioselective adsorption, catalysis, and separation.
