Abstract: | The ligand‐substituted poly(amido amine) dendrimer 2 containing terpyridine ligands located exclusively at the peripheries of the dendrimer and its iron‐containing dendrimer 3 have been synthesized using modification reactions. Cyclic voltammetric studies indicate that the external iron centers on the outer surface of the dendrimer are electrochemically equivalent. The treatment of 2 with Fe2+ ions leads to a dendrimer assembly due to the formation of iron complexes among the ligand‐substituted dendrimers. |
