“…22 When a toluene solution of methyl methacrylate (MMA) and 4¸AIBN was heated at 80°C, the white solid of poly(methyl methacrylate) (PMMA) was obtained in high yield (84% and M w = 1.1 © 10 5 ) for 24 h. This result is comparable to PMMAs prepared by the use of free AIBN under the similar conditions. UV-light irradiation of MMA in a toluene solution of 4¸AIBN gave rise to a similar PMMA solid.…”

In contrast to broad applications of small aromatic rings and π-conjugated wire-like units, the use of large polyaromatic rings in coordination nanostructures has been less developed to date. This review article describes the recent progress of coordinationdriven cages and capsules with multiple polyaromatic panels, such as anthracene, pyrene, and perylene derivatives. In the welldefined cavities, intriguing chemical phenomena can be observed through enhanced interactions with the polyaromatic frameworks.

“…Most recently, Yoshizawa, Chand and co‐workers have developed a “molecular peanut”: a linear double cavity system based on the Yoshizawa group's anthracene panelled single cavity [Pd 2 L 4 ] 4+ cage . The parent single cavity cage system has previously been shown to display rich host–guest chemistry . The authors have joined two of their anthracene‐linked ligands through a central pyridine unit via Suzuki–Miyaura cross‐coupling reactions (Figure ).…”

Discrete metallosupramolecular systems are often macrocyclic or cage-like architectures with an accessible internal cavity. Guest molecules can reside within these cavities and much of the interest in these systems is derived from these fascinating host-guest interactions. A range of potential applications stem from the ability of these metallosupramolecular architectures to encapsulate guests. These applications include catalysis or acting as molecular reaction flasks, the molecular scavenging of pollutants, storage of reactive species, and drug delivery. Multicavity metallosupramolecular architectures combine the ability of large hollow assemblies to bind multiple guests concurrently with the binding specificity associated with small cages. A variety of different approaches to generating separate compartments within a single metallosupramolecular assembly have emerged. These include interpenetrated cages, cages with polytopic ligands that have a long backbone, and molecules that have two or more clefts. This review examines these approaches, and highlights key contributions to the field.

Mimicking biological structures such as fruits and seeds using molecules and molecular assemblies is a great synthetic challenge. Here we report peanut-shaped nanostructures comprising two fullerene molecules fully surrounded by a dumbbell-like polyaromatic shell. The shell derives from a molecular double capsule composed of four W-shaped polyaromatic ligands and three metal ions. Mixing the double capsule with various fullerenes (that is, C60, C70 and Sc3N@C80) gives rise to the artificial peanuts with lengths of ∼3 nm in quantitative yields through the release of the single metal ion. The rational use of both metal–ligand coordination bonds and aromatic–aromatic π-stacking interactions as orthogonal chemical glue is essential for the facile preparation of the multicomponent, biomimetic nanoarchitectures.
