Triplet-triplet energy transfer in artificial and natural photosynthetic antennas.
In photosynthetic organisms, protection against photooxidative stress due to singlet oxygen is provided by carotenoid molecules, which quench chlorophyll triplet species before they can sensitize singlet oxygen formation. In anoxygenic photosynthetic organisms, in which exposure to oxygen is low, chlorophyll-to-carotenoid triplet-triplet energy transfer (T-TET) is slow, in the tens of nanosecon...
متن کاملTriplet-triplet energy-transfer coupling: theory and calculation.
Triplet-triplet (TT) energy transfer requires two molecular fragments to exchange electrons that carry different spin and energy. In this paper, we analyze and report values of the electronic coupling strengths for TT energy transfer. Two different methods were proposed and tested: (1) Directly calculating the off-diagonal Hamiltonian matrix element. This direct coupling scheme was generalized ...
متن کاملTriplet exciplexes as energy transfer photosensitisers.
Experimental evidence is provided for the occurrence of triplet-triplet energy transfer from benzoylthiophene-indole exciplexes to naphthalenes with a remarkable stereodifferentiation; chiral recognition is also observed in the decay of the generated naphthalene triplets.
متن کاملFörster resonance energy transfer beyond 10 nm: exploiting the triplet state kinetics of organic fluorophores.
Inter- or intramolecular distances of biomolecules can be studied by Förster resonance energy transfer (FRET). For most FRET methods, the observable range of distances is limited to 1-10 nm, and the labeling efficiency has to be controlled carefully to obtain accurate distance determinations, especially for intensity-based methods. In this study, we exploit the triplet state of the acceptor flu...
متن کاملExcited-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...
