Amphiphilic hybrid dendrons containing benzyl ether, naphthyl methyl ether, and biphenyl methyl ether units with different alkyl carboxylates at the apex of the dendron self-assemble into a diversity of unprecedented supramolecular structures, including hollow and nonhollow singly or doubly segregated supramolecular columns and vesicles. A combination of experiments involving XRD analysis, simulation of powder X-ray diffractograms, reconstruction of the electron density distributions, and molecular modeling suggested that the supramolecular columns and vesicles self-organized from the first generation hybrid dendrons exhibit polyhedral shapes that are intrinsic characteristic of all bilayered structures. This new self-assembly mechanism is correlated with the dendron solid  angle, the structure of the apex building block, and the addition of branching points in the alkyl chains attached to the periphery of the  dendrons.
