Time-Resolved Electron Transfer in Porphyrin-Coordinated Ruthenium Dimers: From Mixed-Valence Dynamics to Hot Electron Transfer

Autor: Clifford P. Kubiak, Allison M. Brown, Jonas Petersson, Leif Hammarström, Jane Henderson

Publikováno v: The Journal of Physical Chemistry C. 119:4479-4487

Presented here is the first effort to study the formation and dynamics of the triruthenium cluster (Ru3O) pyrazine-bridged dimer mixed-valence state. Femtosecond transient absorption spectroscopy was implemented to follow photoinduced electron-transf

A Ruthenium Complex-Porphyrin-Fullerene-Linked Molecular Pentad as an Integrative Photosynthetic Model

Autor: Masanori Yamamoto, Leif Hammarström, Jonas Petersson, Jens Föhlinger, Hiroshi Imahori

Publikováno v: Angewandte Chemie (International ed. in English). 56(12)

A ruthenium complex, porphyrin sensitizer, fullerene acceptor molecular pentad has been synthesized and a long-lived hole-electron pair was achieved in aqueous solution by photoinduced multistep electron transfer: Upon irradiation by visible light, t

Ultrafast Electron Transfer Dynamics in a Series of Porphyrin/Viologen Complexes: Involvement of Electronically Excited Radical Pair Products

Autor: Jonas Petersson, Leif Hammarström

Publikováno v: The journal of physical chemistry. B. 119(24)

Ultrafast electron transfer was studied for a series of metalloporphyrin/bipyridinium complexes in aqueous solution, using laser excitation in the Soret or Q-bands of the porphyrin. Electron transfer occurred before electronic and vibrational relaxat
