Abstract

Viologen-carbazole linked compounds quenched photoexcited tris(2,2'-bipyridine)ruthenium(II), abbreviated to Ru-trisbpy, much more efficiently than simple viologen in aqueous solutions. The observation was ascribed to enhanced electron-transfer to partially dehydrated viologen as deduced from spectroscopic-and electeochemical evidences.
