A novel phenylene viologen functionalized bis(terpyridine) is synthesized and characterized with ¹H NMR and Maldi-tof-MS. This rod-like and π-conjugated molecule, 1,1'-[4'-(4-phenyl)-2,2:6′,2″- terpyridine-4,4′-bipyridine-1,1′-diium dichloride (TPV⁺²2Cl⁻), synthesized by Zincke reaction of 4'-(4-aminophenyl)-2,2:6′,2″-terpyridine with 1,1′-bis (2,4-dinitrophenyl)-4,4′-bipyridine,1,1′-diium dichloride, exhibited strong absorption and fluorescence in wide UV and visible wavelength range. It complexes with Fe- and Ru- ions and can self-assemble into metallo-supramolecular polymers in solution, which can be coated on ITO-glass. The electrochemical characteristics of TPV⁺²2Cl⁻ and its Fe-TPV⁺²-BF₄ supramolecular polymer in solution were studied with cyclic voltammetry. Four different color states, colorless (transparent), purple, reddish brown and grayish green, were observed in a cycle of redox reaction during the cyclic voltammetry scanning. A simple liquid electrochromic device with the Fe-TPV⁺²-BF₄ supramolecular polymer film as working electrode, and with LiClO₄ aqueous and K₃Fe(CN)₆, was fabricated. It can be colored/bleached reversibly between purple and green-yellowish colors by switching the applied voltage from 0 to 0.8 V. The π-conjugation among the bis(terpyridine)s and the phenylene viologen leads the subunits electronically and chemically connected. This interesting viologen functionalized bis(terpyridine) dye will find applications in wide ranges.
