Homoleptic Ru(II) complex with terpyridine ligands appended with terthiophene moieties: Synthesis, characterization and electropolymerization

A new ruthenium(II) complex, [Ru(TTT)2][PF6]2 (TTT=4′-[(2,2′:5′,2″-terthien-3′-yl)methoxy]-2,2′:6′,2″-terpyridine) was synthesized. The spectroscopic and electrochemical characterization of the terpyridine-coordinated species, the electrosynthesis of the corresponding polymer P[Ru(TTT)2] and its optical and electrochemical characterization are reported.
