Supramolecular nanocapsule 1 ⋅(BArF) 8 is able to sequentially and selectively entrap recently discovered U 2 @C 80 and unprecedented Sc 2 CU@C 80 , simply by soaking crystals of 1 ⋅(BArF) 8 in a toluene solution of arc‐produced soot. These species, selectively and stepwise absorbed by 1 ⋅(BArF) 8 , are easily released, obtaining highly pure fractions of U 2 @C 80 and Sc 2 CU@C 80 in one step. Sc 2 CU@C 80 represents the first example of a mixed metal actinide‐based endohedral metallofullerene (EMF). Remarkably, the host–guest studies revealed that 1 ⋅(BArF) 8 is able to discriminate EMFs with the same carbon cage but with different encapsulated cluster and computational studies provide support for these observations.
