Shape control : Fluorination of the n ‐dodecan‐1‐yloxy groups of the amphiphilic (3 , 4 , 5) 2 G2‐CO 2 Me monodendron changes the shape of the monodendron from an all‐ trans ‐conical to an all‐ gauche ‐crown or all‐ trans ‐tapered conformation as well as the mode of self‐assembly from a spherical to a pyramidal columnar supramolecular dendrimer (see schematic representation).
