ABSTRACT
The use of DAB dendrimers in halogen bonding-based crystal engineering is reported. The DAB-dendr-(NHC6F4I)22 self-assembles with (E)-1,2-bis-(4-pyridyl)-ethylene in a 1:2 supramolecular adduct, whose crystal lattice is composed of 5-fold interpenetrated sql networks, which is the highest degree for a square topology reported so far. The synthesis and coordination properties of higher generation dendrimers is also described, both in the liquid state and in solution.
