“…Several 3D metal‐organic constructs of varied topologies and geometries have been prepared by many groups around the world [12–20] . In analogy to natural receptors, the cavities within MOCs can express molecular recognition, [21–24] protect and stabilize reactive guests, [25] impart unusual conformations, or facilitate their chemical conversion in aqueous environment [26] …”

Natural products are central to the organic synthesis field and attract immense interest due to their biological activity and wide industrial use. However, many suffer from poor aqueous solubility, instability under certain conditions, or bear complex composition, limiting their investigation and derivatization. Metal–organic cages (MOCs) are promising molecular receptors to solubilize in water, preserve, or transform natural products. This contribution features examples of MOCs that encapsulate naturally occurring compounds and synthetic congeners in aqueous media, protecting them from photodegradation or hydrolysis. We highlight cases of cages used as molecular vessels to promote chemical conversion and derivatization of natural substances. This review aims to provide an overview of the possibilities of using MOCs to bring about new properties and reactivity on natural products, offering methodological insights into cage operation for enhancing their activity and the engineering of further aqueous applications involving natural compounds, synthetic derivatives, and biomolecules.

“…In 2011, Moon, Chun and co-workers synthesized a cubohemioctahedral MOC based on 2,7-naphthalenedicarboxylate and Cu 2 + (MOC-18). MOC-18 was further linked by a series of flexible diamine ligands to yield three amorphous compounds (15)(16)(17), as shown in Figure 7a. The N 2 sorption isotherms measured reveal that bulk MOC-18 is a microporous material, while 15-17 possess surface features that are clearly distinct from those of bulk MOC-18.…”

“…[11] In addition, the combination of the metal ion centre, the functional ligand and the inner nanosized space of these coordination molecules allows for various applications, such as in catalysis, sensing, separation, and drug delivery. [12][13][14][15] The biggest structural difference between MOCs and MOFs is that MOFs are infinite structures connected by coordination bonds, while MOCs are discrete structures. Therefore, MOCs have better solubility than MOFs.…”

Metal‐organic cages (MOCs) that assemble from metal ions or metal clusters and organic ligands have attracted the interest of the scientific community because of their various functional coordination cavities. Unlike metal‐organic frameworks (MOFs) with infinite frameworks, MOCs have discrete structures, making them soluble and stable in certain solvents and facilitating their application as starting reagents in the further construction of single components or composite materials. In recent years, increasing progress has been made in this field. In this review, we introduce these works from the perspective of design strategies, and focus on how presynthesized MOCs can be used to construct functional materials. Finally, we discuss the challenges and development prospects in this field.

Pseudo‐heterolepticity in Low‐Symmetry Metal‐Organic Cages

Heteroleptic metal-organic cages, formed through integrative self-assembly of ligand mixtures, are highly attractive as reduced symmetry supramolecular hosts. Ensuring high-fidelity, non-statistical self-assembly, however, presents a significant challenge in molecular engineering due to the inherent difficulty in predicting thermodynamic energy landscapes. In this work, two conceptual strategies are described that circumvent this issue, using ligand design strategies to access structurally sophisticated metal-organic hosts. Using these approaches, it was possible to realise cavity environments described by two inequivalent, unsymmetrical ligand frameworks, representing a significant step forward in the construction of highly anisotropic confined spaces.
