The syntheses and characterization of six ditopic ligands which contain polyethyleneoxy-substituted naphthalene spacers connecting two 2,2′:6′,2″-terpyridine metal-binding domains are described. The ligands, L, have been used to prepare two series of ruthenium(II) complexes: linear complexes of type [(tpy)Ru(L)Ru(tpy)]4+ were prepared as models for polymeric species, and metallomacrocyclic species

A new ditopic ligand based upon a 2,7-disubstituted naphthalene bearing two terpy-terminated bis(ethyleneoxy) substituents has been prepared and shown to give a conformationally locked [1 + 1] macrocycle upon reaction with iron(II) salts.
