Allosteric Interactions in Coordination Cages
… regulation systems, a series of metal-organic cages capable of both the peripheral and internal encapsulation of guests are presented: octahedra capable of accommodating two guests in different locations simultaneously; cuboctahedral receptors that bind fullerenes with all-or-nothing positive …

Coordination Cages: Beyond The Solution State
Metal-organic coordination cages can be assembled from simple building blocks to form a wide range of structure types such as Platonic and Archimedean solids. Such architectures are able to encapsulate a diverse array of molecular guests in the solution state, from both organic and aqueous media. …

Sensors: Metal-Organic Cages and Graphene
… functionalize the graphene using metal-organic cages. The metal-organic cages can encapsulate a small range of guests, however their binding inside the cage has not been investigated in the presence of graphene. Therefore, we present a novel investigation into the use of pristine graphene as a …

Structures and Applications of Porous Coordination Cages
Well defined porous coordination cages (PCCs) are cage-like compounds constructed from the self-assembling of organic ligands and metal ions through coordination interactions. These metalorganic materials can exist in solution as standalone cage-like host systems that can be structurally tuned …

Microporous materials fabricated from discrete molecular cages
… we test the hypothesis that discrete molecular cages with non-collapsible pores are building blocks for porous solids by preparing molecular cages via alkyne metathesis. We demonstrate that molecular pores can be rationally synthesized from tritopic organic precursors in a single step and …

Stimuli-Induced Structural Transformations of Metal–Organic Cages
… Inspired by these systems, metal–organic cages (MOCs) have emerged as versatile synthetic platforms capable of undergoing controlled transformations in response to diverse stimuli. Studying the structural responsiveness of MOCs not only deepens our understanding of dynamic self-assembly …

The Design of Cyanometallate Cages for Alkali Ion Separation
The metal sulfide cluster, [(cymene)2Ru3S 2(NCMe)3]2+, reacts with various equivalents of sulfide to give rise to cluster-of-clusters i.e. [(cymene)4Ru 5S4]2+ and [(cymene)6Ru9S 8]2+. The new valence isomer of the [(cymene)4Ru 4S3]2+ was characterized and shown to convert to the black Roussin …

Sulfur Rich Transition Metal-Main Group Heterocycles and Cages
The reactivity of elemental sulfur homocycles has long been postulated to occur via highly reactive thiopolysulfide (S=S) ring intermediates. Consistent with the reactivity associated with these postulated S=S intermediates is that observed for the organoperthiophosphinic acid anhydrides, …

Reversible Directed Phase Transfer of M4IIL4 and M4IIL6 Cages
… of supramolecular chemistry. Metallo-organic cages are an important breakthrough in the encapsulation and transport of small molecules, providing a crucial platform for the development of systems chemistry. Binding a network member within a tetrahedral cage allows it to be hidden and then …

Non-Equilibrium Transport Across Liquid Membranes Using Coordination Cages
The host-guest chemistry of coordination cages underscores their utility in selectively extracting molecules, offering potential for chemical separation systems. However, the equilibrium constraint within bulk liquid membrane systems limits molecular transport efficiency to 50%, hindering …

Subcomponent self-assembly of cages and mechanically interlocked molecules
… the construction of a wide range of discrete cages, often containing internal cavities, that have potential applications in sensing, catalysis and molecular purifications. The geometry of the cage can be controlled by the choice of metal ion and ligands. PdII and PtII are commonly used to …

Coordination Cages as a Scaffold for Permanently Porous Liquids
… We present the first adaptation of coordination cages into porous liquids by functionalizing a series coordination cages of different sizes and structures with alkylimidazolium and PEG-imidazolium moieties. The alkylimidazolium-functionalized cages showed increased solubility in similarly …

Biofunctionalised Coordination Cages and Quantified Speciation in Supramolecular Mixtures
Coordination cages formed by supramolecular self-assembly are excellent candidates for the selective encapsulation of molecules and sheltering these guests from their environment after uptake. The easily tuneable nature of these 3D-structures can make them versatile carriers in applications such as …

Feeding of Black Bullheads Ictalurus Melas (Rafinesque) in Experimental Cages
… collected from Lake Poinsett, were grown in five cages each with a water volume of 2.6 m³ and five cages each with a volume of 3.86 m³. The larger cages contained nearly 60 percent of the total 323 m³ of water volume in the cages. No significant difference in fish growth between the two cage sizes …

On the Structural Adaptability and Dynamics of Metal-Organic Cages
Metal-organic cages are molecular receptors that enable selective molecular recognition and catalysis, yet most current cage systems employ rigid building blocks that limit guest accommodation and environmental adaptability. Developing cages that combine structural integrity with conformational …

Self-Assembly of Enantiopure Subcomponents into Functional Metal–Organic Cages
Metal–organic cages possessing enclosed cavities have been shown to bind guest molecules selectively and mediate catalysis with improved reactivity and selectivity, among other applications. However, the use of enantiopure metal–organic cages for enantioselective applications has been limited both …
