✦ Synopsis

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 Fe 2+ ions leads to a dendrimer assembly due to the formation of iron complexes among the ligand-substituted dendrimers.

## Abstract The __para__‐substituted tridentate ligands 2,6‐bis[1‐(3,5‐dimethoxybenzyl)benzimidazol‐2‐yl]‐4′‐X‐phenyl)‐pyridine (X = H: L^3^; X = NO~2~: L^4^; X = NEt~2~: L^5^) have been synthesized in six steps using Kröhnke reactions. Spectroscopic results show that the electronic properties of t
