title: Microsecond charge recombination in a linear triarylamine-Ru(bpy)3(2+)-anthraquinone triad.
abstract: Linear triads with ruthenium photosensitizers are frequently based on the Ru(terpyridine)(2)(2+) unit. We report on vectorial photoinduced electron transfer in a linear triad based on the Ru(bipyridine)(3)(2+) photosensitizer. Electron-hole separation over a 22 Å-distance is established with a quantum yield greater than 64% and persists for 1.3 μs in acetonitrile.
