The modular approaches towards 2,2′:6′,2′′-terpyridines and U-/S-shaped terpyridines are combined to yield a new family of ditopic ligands. Functionalized Kröhnke-type terpyridines were used as key building blocks for the construction of hetero-bis(terpyridine)s. The described compounds might serve as new templates for the self-assembly towards new metallosupramolecular functional materials.
