The mode of the self‐assembly of (3,4,5) 2 G2‐CO 2 Me monodendrons changes from a spherical to a pyramidal supramolecular dendrimer upon replacement of the aliphatic chains by partially fluorinated chains. This metamorphosis was verified with a combination of small‐ and wide‐angle X‐ray diffraction, electron density calculations, and molecular modeling studies. For more information on this process, see the Communication by V. Percec et al. on page 4338 ff.
