Electron Transfer Reaction to Triplet Excited State of Fullerenes in Solution. Comparison with the Rehm-Weller Equation.

Electron transfer from the benzophenone triplet excited state directs the photochemical synthesis of gold nanoparticles.

The rarely recognized electron donating ability of the benzophenone triplet excited state provides an unusual route for the photochemical synthesis of gold nanoparticles.

Electron Transfer Quenching of Dye Triplets by No~ and N~. a Spin-orbit Coupling Effect on the Radical Yield

Electron transfer between electronically excited states and electron donors or acceptors in the ground state has been established as an important mechanism for the quenching of excited states. The paper of Rehm and Weller [1], demonstrating for several aromatic excited singlets and numerous aromatic quenchers in acetonitrlle a clear-cut correlation between the quenching rate constant kq and the...

Excited-state energy transfer pathways in photosynthetic reaction centers: 5. Oxidized and triplet excited special pairs as energy acceptors

In bacterial photosynthetic reaction centers, ultrafast singlet excited-state energy transfer occurs from the monomeric bacteriochlorophylls, B, and bacteriopheophytins, H, to the homodimer special pair, P, a pair of strongly interacting bacteriochlorophylls. Using fluorescence upconversion spectroscopy, energy transfer to the special pair can be monitored by observing the decay of B emission a...

Electron Localization Dynamics in the Triplet Excited State of [ Ru ACHTUNGRE ( bpy ) 3 ] 2 + in Aqueous Solution

Ultrafast excited state dynamics of the perylene radical cation generated upon bimolecular photoinduced electron transfer reaction.

The ultrafast ground state recovery (GSR) dynamics of the radical cation of perylene, Pe(*+), generated upon bimolecular photoinduced electron transfer in acetonitrile, has been investigated using pump-pump-probe spectroscopy. With 1,4-dicyanobenzene as electron acceptor, the free ion yield is substantial and the GSR dynamics of Pe(*+) was found to depend on the time delay between the first and...
