“…Moreover, the tetragonal prismatic cage design endows four large entrances that enable an unprecedented example of inclusion and release of fullerenes within a molecular cage in the solid state, thus showing a sponge-like behaviour that allows for rapid purification of fullerene mixtures. 8 cages (X ¼ CF 3 SO 3 or BArF (BArF ¼ tetrakis [3,5-…”

Since fullerenes are available in macroscopic quantities from fullerene soot, large efforts have been geared toward designing efficient strategies to obtain highly pure fullerenes, which can be subsequently applied in multiple research fields. Here we present a supramolecular nanocage synthesized by metal-directed self-assembly, which encapsulates fullerenes of different sizes. Direct experimental evidence is provided for the 1:1 encapsulation of C 60 , C 70 , C 76 , C 78 and C 84 , and solid state structures for the host-guest adducts with C 60 and C 70 have been obtained using X-ray synchrotron radiation. Furthermore, we design a washingbased strategy to exclusively extract pure C 60 from a solid sample of cage charged with a mixture of fullerenes. These results showcase an attractive methodology to selectively extract C 60 from fullerene mixtures, providing a platform to design tuned cages for selective extraction of higher fullerenes. The solid-phase fullerene encapsulation and liberation represent a twist in host-guest chemistry for molecular nanocage structures.

The discovery of the fullerenes has revolutionalized the chemistry of carbon. For the first time a molecular form of the element carbon is available that can be manipulated and functionalized by the wide range of techniques available to molecular and materials scientists. In a very short space of time the fullerenes and their derivatives have been found to display many fascinating physical and chemical properties, and the astonishing pace of development in fullerene research is ample testimony to their great potential.
