| Abstract: | The first generation molecule of glutamic acid-based dendrons on a 1, 3,5-benzenetricarbonyl core leads to a cylindrical assembly as demonstrated by single crystal x-ray diffraction. The benzene pi-pi stack (A) is stabilized by vertical NH...O===C hydrogen bonding with each subunit participating in three intermolecular hydrogen bonds related by three-fold rotation symmetry. |
