All clicking into place : Self‐complementarity between a bis(crown ether) derivative and a bisammonium fullerene leads to the formation of a stable noncovalent macrocyclic 1:1 complex (see schematic representation). The binding constant for this complex is three orders of magnitude larger than that for other closely related systems as a result of the two‐center host–guest topography.
