Purification of Uranium-based Endohedral Metallofullerenes (EMFs) by Selective Supramolecular Encapsulation and Release Fuertes Espinosa, Carles Gómez Torres, Alejandra Morales Martínez, Roser Rodríguez Fortea, Antonio Garcia Simon, Cristina Gándara, Felipe Imaz, Inhar Juanhuix, Judith Maspoch Comamala, Daniel Poblet Rius, Josep M. Echegoyen, Luis Ribas, Xavi Endohedral metallofullerenes Supramolecular capsules Uranium Supramolecular nanocapsule 1⋅(BArF) is able to sequentially and selectively entrap recently discovered U@C and unprecedented ScCU@C, simply by soaking crystals of 1⋅(BArF) in a toluene solution of arc-produced soot. These species, selectively and stepwise absorbed by 1⋅(BArF), are easily released, obtaining highly pure fractions of U@C and ScCU@C in one step. ScCU@C represents the first example of a mixed metal actinide-based endohedral metallofullerene (EMF). Remarkably, the host-guest studies revealed that 1⋅(BArF) is able to discriminate EMFs with the same carbon cage but with different encapsulated cluster and computational studies provide support for these observations. 2018 Article https://ddd.uab.cat/record/206942 urn:10.1002/anie.201806140 urn:oai:ddd.uab.cat:206942 urn:scopus_id:85051848496 urn:articleid:15213773v57n35p11294 urn:wos_id:000442340000030 urn:altmetric_id:44050851 urn:icn2uab:5610846 urn:oai:egreta.uab.cat:publications/15d14588-3956-4274-baee-87a05b29a1fb eng Agència de Gestió d'Ajuts Universitaris i de Recerca 2017/SGR-264 Agència de Gestió d'Ajuts Universitaris i de Recerca 2017/SGR-629 Ministerio de Economía y Competitividad CTQ2016-77989-P Agencia Estatal de Investigación CTQ2017-87269-P Ministerio de Economía y Competitividad SEV-2013-0295 Angewandte Chemie (International ed.
