Recent advances in supramolecular fullerene chemistry

Abstract

We review recent work at the interface of supramolecular chemistry and fullerene chemistry. We focus on selective fullerene functionalization, host–guest chemistry, non-covalent dyads, mechanically interlocked architectures and 2D/3D assemblies.

Hierarchical Self‐Assembly of Curved Aromatics: From Donor–Acceptor Porphyrins to Triply Periodic Minimal Surfaces

“…[56] We supposed that the large, negatively curved outer faces of the (ZnP) 3 trimer might be capable of co-assembly with convex π surfaces, such as those of fullerenes. [57] Indeed, crystallization of (ZnP) 3 from chlorobenzene containing ca. 5 equiv.…”

Negatively Curved Octagon‐Incorporated Aza‐nanographene and its Assembly with Fullerenes

“…The curvature in NGs can enhance their supramolecular interactions with fullerenes, rendering them potential fullerene hosts. [22] As opposed to bowl-shaped NGs with positive curvatures, [23] the host-guest assembly of negatively curved NGs with fullerenes has rarely been explored. Campaña and co-workers recently described the elusive complexation study of saddle-shaped heptagon-containing hexa-peri-benzocoronene (hept-HBC) derivatives with fullerenes.…”

Covalently linked thieno[2,3-b]thiophene-fullerene dimers: synthesis and physical characterization

“…2 C 60 possesses unique characteristics as a supramolecular guest due to its exceptional icosahedral symmetry ( I h ), which possesses twelve pentagonal rings surrounded by hexagons, substantial size, inherent rigidity, precisely defined curvature, and absence of heteroatoms. 3 Also, it is one of the most commonly used n-type materials for efficient and stable optoelectronic devices due to its unique physicochemical properties, availability, and extended conjugated π-systems. 4 The electrochemical properties of fullerene derivatives, which make them ideal for the fabrication of contemporary nanoengineered materials and devices, attracted scientists to research and design new electron-donor and electron-acceptor compounds.…”

“…4 The electrochemical properties of fullerene derivatives, which make them ideal for the fabrication of contemporary nanoengineered materials and devices, attracted scientists to research and design new electron-donor and electron-acceptor compounds. It is also considered the state-of-the-art material in many applications 3 such as materials science, 5 antiviral therapy, 6 photodynamic therapy (PDT), 7,8 screen printed systems, 9,10 rechargeable batteries, 11 layered materials for organic and perovskite solar cells, 12,13 biosensors, 14 and organic chemistry. 15 Due to its dual electrophilic and nucleophilic properties as well as its noteworthy redox activity, it can act as an electron acceptor.…”
