Excitation energy transfer and trapping in higher plant photosystem II complexes with different antenna sizes [PDF]
, 2011 700 cm(-1)) and a slow relaxation of the radical pair to an irreversible state (similar to 150 ps). Somewhat unexpectedly, we had to reduce the energy-transfer and charge-separation rates in complexes with decreasing size to obtain optimal fits.

Energy transfer in Light-Harvesting complexes LHCII and CP29 of spinach studied with Three Pulse Echo Peak Shift and transient grading [PDF]
, 2003 Three pulse echo peak shift and transient grating (TG) measurements on the plant light-harvesting complexes LHCII and CP29 are reported. The LHCII complex is by far the most abundant light-harvesting complex in higher plants and fulfills several ...

The chlorosome: a prototype for efficient light harvesting in photosynthesis [PDF]
, 2010 Three phyla of bacteria include phototrophs that contain unique antenna systems, chlorosomes, as the principal light-harvesting apparatus. Chlorosomes are the largest known supramolecular antenna systems and contain hundreds of thousands of BChl c/d/e ...

From isolated light-harvesting complexes to the thylakoid membrane: a single-molecule perspective
Nanophotonics, 2018 The conversion of solar radiation to chemical energy in plants and green algae takes place in the thylakoid membrane. This amphiphilic environment hosts a complex arrangement of light-harvesting pigment-protein complexes that absorb light and transfer ...

Bio-inspired building blocks for all-organic metamaterials from visible to near-infrared
Nanophotonics, 2023 Light-harvesting complexes in natural photosynthetic systems, such as those in purple bacteria, consist of photo-reactive chromophores embedded in densely packed “antenna” systems organized in well-defined nanostructures.

Carotenoid-dependent singlet oxygen photogeneration in light-harvesting complex 2 of Ectothiorhodospira haloalkaliphila leads to the formation of organic hydroperoxides and damage to both pigments and protein matrix [PDF]
PeerJEarlier, it was suggested that carotenoids in light-harvesting complexes 2 (LH2) can generate singlet oxygen, further oxidizing bacteriochlorophyll to 3-acetyl-chlorophyll.
