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 π–π stack (A) is stabilized by vertical NH OC hydrogen bonding with each subunit participating in three intermolecular hydrogen bonds related by three‐fold rotation symmetry. © 2000 John Wiley & Sons, Inc.
