TL;DR: This tutorial review describes the use of 2,2':6',2''-terpyridine (tpy) metal-binding domains in supramolecular chemistry.
Abstract: This tutorial review describes the use of 2,2′:6′,2″-terpyridine (tpy) metal-binding domains in supramolecular chemistry. The origins of tpy chemistry are described and the reasons for its current importance in supramolecular chemistry are explained. Examples of tpy compounds in a wide variety of supramolecular chemistry are presented. The content will be of interest to organic, inorganic, supramolecular and nanoscale chemists.

TL;DR: In this paper, a discussion on the coordination chemistry of 2,2': 6', 2'-terpyridine and higher oligopyridines is presented.
Abstract: Publisher Summary This chapter presents a discussion on the coordination chemistry of 2,2’: 6’, 2”-terpyridine and higher oligopyridines. The potentially terdentate ligand 2,2’: 6’, 2”-terpyridine presented, was first isolated by Morgan and Burstall as one of the numerous products from the reaction of pyridine with iron (III) chloride. There has been a considerable increase in the use of these ligands in recent years, prompted in part by the attractive photochemical and photophysical properties exhibited by complexes of the related ligands 2,2’-bipyridine and 1,10-phenanthroline. The chapter discusses stabilization of unusual complexes and states that low oxidation states are characterized by an excess of electron density at the metal atom; stabilization may be achieved by the use of ligands capable of reducing that electron density. One of the simplest ways to reduce the electron density is to design ligands with low-lying vacant orbitals of suitable symmetry for overlap with filled metal orbitals. This results in the transfer of electron density from the metal to the ligand (back-donation). In general, ligand nonbonding or π antibonding orbitals are of the correct symmetry for such overlap. The oligopyridines are ideally suited to such roles; they possess a filled highest occupied molecular orbital (HOMO) and a vacant lowest unoccupied molecular orbital (LUMO) of suitable energies for interaction with metal d orbitals. The chapter also discusses monodentate, bidentate, and bridging; terdentate and higher polydentate; cyclometallated, and others.
