Naturforsch. 2010, 65b, 1 – 7; received October 1, 2009 The electron density of the C70 fullerene C70(C2F5)10 was determined from a high-resolution X-ray data set measured with synchrotron radiation (beamline F1 of Hasylab/DESY, Germany) at a temperature of 100 K. With 140 atoms in the asymmetric unit this fullerene belongs to the largest problems examined until now by electron density methods. Using the QTAIM formalism quantitative bond topological and atomic properties have been derived and compared with the results of theoretical calculations on the title compound and on free C70. Key words: Fullerenes, Electron Density, Topological Analysis, Synchrotron Radiation Introduction Although recent technical and methodical advances made experimental electron density (ED) determina- tions possible also on larger molecules, fullerenes with 60 or more atoms are still a major challenge. Their in- vestigation is complicated by the generally poor crystal quality and by the high mobility of these molecules in the crystal structure. Since their discovery in the mid- eighties a considerable number of more than 800 X-ray structures of fullerenes and fullerene derivatives are listed in the Cambridge Data File [1].

  • Sponge-Like Molecular Cage for Purification of Fullerenes
    ARTICLE Received 24 May 2014 | Accepted 13 Oct 2014 | Published 26 Nov 2014 DOI: 10.1038/ncomms6557 Sponge-like molecular cage for purification of fullerenes Cristina Garcı´a-Simo´n1, Marc Garcia-Borra`s1, Laura Go´mez1,2, Teodor Parella3,Sı´lvia Osuna1, Jordi Juanhuix4, Inhar Imaz5, Daniel Maspoch5,6, Miquel Costas1 & Xavi Ribas1 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 C60, C70,C76,C78 and C84, and solid state structures for the host–guest adducts with C60 and C70 have been obtained using X-ray synchrotron radiation. Furthermore, we design a washing- based strategy to exclusively extract pure C60 from a solid sample of cage charged with a mixture of fullerenes. These results showcase an attractive methodology to selectively extract C60 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. 1 Institut de Quı´mica Computacional i Cata`lisi and Departament de Quı´mica, Universitat de Girona, Campus Montilivi, Girona, Catalonia 17071, Spain. 2 Serveis Te`cnics de Recerca (STR), Universitat de Girona, Parc Cinetı´fic i Tecnolo`gic, Girona, Catalonia 17003, Spain. 3 Servei de RMN and Departament de Quı´mica, Facultat de Cie`ncies, Universitat Auto`noma de Barcelona (UAB), Campus UAB, Bellaterra, Catalonia 08193, Spain.

See DOI: 10.1039/x0xx00000x Novel naphthalene-based 5·(BArF)8 capsule allows for the size-selective inclusion of C60 from fullerene mixtures. Its size selectivity towards C60 has been rationalized by its dynamic adaptability in solution that has been investigated by Molecular Dynamics.
