“…Very recently, on the basis of a novel strategy that utilized dynamic heteroleptic complexation in conjunction with ligand multivalency, the Chan group successfully reported the construction of a rationally designed 10‐nm‐sized cuboctahedron S57 . [ 104 ] The complexation of a tetratopic ligand L43 and L44 with Cd(II) in a stoichiometric ratio of 3:4:12 produced a highly symmetric structure, i.e., cuboctahedron ( Figure ). The resultant double‐shell assembly, wherein the inner and outer cuboctahedral cages were interlinked by conformationally flexible and adaptable alkyl spacers, was thought to be reminiscent of so‐called “cable‐strut tensile” structure, which mitigated the angle strain derived from the geometrically mismatched vertices.…”

Terpyridine (tpy)‐based 3D discrete metallosupramolecular architectures, which are often inspired by polyhedral geometry and the biological structures found in nature, have drawn significant attention from the community of metallosupramolecular chemistry. Because of the linear tpy–M(II)–tpy connectivity, the creation of sophisticated 3D metallosupramolecules based on tpy remains a formidable synthetic challenge. Nevertheless, with recent advancement in ligand design and self‐assembly, diverse 3D metallosupramolecular polyhedrons, such as Platonic solids, Archimedean solids, prims as well as Johnson solids, have been constructed and their potential applications have been explored. This review summarizes the progress on tpy‐based discrete 3D metallosupramolecules, aiming to shed more light on the design and construction of novel discrete architectures with molecular‐level precision through coordination‐driven self‐assembly.

“…Despite the rapid growth of covalent macrocycles and containers, the encapsulation substrates available for host–guest chemistry have been limited to small molecules and ions. − In order to encapsulate larger guest molecules, multiple, cooperative hydrogen bonding interactions have been employed to engineer supramolecular capsules and cages with increasing size . More recently, coordination-driven self-assembly of metallo-supramolecular cages has continuously pushed the limits of non-covalent containers in terms of size, complexity, and diversity . To date, the largest reported metallo-supramolecular cages have a sub-10 nm diameter…”

In the field of supramolecular chemistry, host–guest systems have been extensively explored to encapsulate a wide range of substrates, owing to emerging functionalities in nanoconfined space that cannot be achieved in dilute solutions. However, host–guest chemistry is still limited to encapsulation of small guests. Herein, we construct a water-soluble metallo-supramolecular hexagonal prism with a large hydrophobic cavity by anchoring multiple polyethylene glycol chains onto the building blocks. Then, assembled prisms are able to encapsulate quantum dots (QDs) with diameters of less than 5.0 nm. Furthermore, we find that the supramolecular cage around each QD strongly modifies the photophysics of the QD by universally increasing the rates of QD relaxation processes via ultrafast electron and vibrational energy transfer. Taken together, these efforts expand the scope of substrates in host–guest systems and provide a new approach to tune the optical properties of QDs.

“…2,2′:6′,2″-Terpyridine is a typical tridentate ligand that can bind to various transition metal ions and undergo charge transfer upon coordination with the metal ion. − In 2020, Shi’s group reported that mononuclear terpyridine manganese complexes are effective photosensitizers . Under light conditions, charge transfer easily occurs between the ligand and Mn(II) ion in the terpyridine manganese complex, , and energy is transferred to the nearby ground state oxygen molecules to generate activated singlet oxygen 1 O 2 .…”

In coordination-driven metal−organic cages, the transition metal ions are generally utilized as linkages. Employment of its unique properties with the aim of achieving specific applications still presents great challenges. Herein, we report a decametric metal−organic cage named pentagonal prism (Mn 20 LC 10 ) based on Tpy-Mn(II)-Tpy connectivity (Tpy = 2,2′:6′,2″-terpyridine) in which Mn(II) serves as a linker and endows the resulting metal−organic cage with good photosensitivity. In the photooxidation of benzaldehyde, pentagonal prism Mn 20 LC 10 showed a significantly increased level of 1 O 2 production, the fastest conversion time, good recyclability, and substrate versatility due to its greatly improved intersystem crossing ability. Notably, the abundant active sites of metal pentagonal prism Mn 20 LC 10 enable its photooxidation under solvent-free and daylight conditions. This work provides approaches for the development of inexpensive, green, and low-cost photosensitizer systems.
