Reply to Comment on “Measurement of Ultrafast Photoinduced Electron Transfer from Chemically Anchored Ru−Dye Molecules into Empty Electronic States in a Colloidal Anatase TiO₂ Film”

Spectral Characterization of the One-Electron Oxidation Product of cis-Bis(isothiocyanato)bis(4,4‘-dicarboxylato-2,2‘-bipyridyl) Ruthenium(II) Complex Using Pulse Radiolysis

“…While Moser et al 1 expressed their concern regarding the stability of oxidized sensitizer, Hannappel et al 2 suggested that the differences could arise from the nature of surrounding environment and experimental conditions. (Their femtosecond measurements were carried out in an UHV chamber.)…”

Ultrafast fluorescence studies of dye sensitized solar cells

“…Much effort has been devoted to this aim in the past 15 years, mainly using nanosecond and femtosecond transient absorption spectroscopy in the visible, near-IR, and mid-IR spectral regions. [2][3][4][5][6][7][8][9][10][11][12] Overall these studies concluded that at least part of the photo-induced electron transfer in the RuN3-TiO 2 films occurs in o100 fs. This was also one of the reasons to believe that the electron injection may occur from non-thermalized vibrationally excited states prior to internal energy relaxation in the sensitizer.…”

Polychromatic femtosecond fluorescence studies of metal–polypyridine complexes in solution

“…A central issue for the efficiency of dye-sensitized solar cells is the detailed understanding of the mechanisms and time scales of electron injection. Much effort has been devoted to this aim in the past 15 years, mainly using nanosecond to femtosecond transient absorption spectroscopy in the visible, near-IR, and mid-IR spectral regions [5][6][7][8][9][10][11][12][13][14][15][16][17]. Overall, it was concluded that injection spans several time scales, ranging from a few tens of femtoseconds from the Franck-Condon accessed state to several picoseconds from the 3 MLCT state, which is populated by intersystem crossing (ISC) from the 1 MLCT state.…”
