Colloidal PbS Nanocrystals with Size‐Tunable Near‐Infrared Emission: Observation of Post‐Synthesis Self‐Narrowing of the Particle Size Distribution
Coherently wired light-harvesting in photosynthetic marine algae at ambient temperature
Observations provide compelling evidence for quantum-coherent sharing of electronic excitation across the 5-nm-wide proteins under biologically relevant conditions, suggesting that distant molecules within the photosynthetic proteins are ‘wired’ together by quantum coherence for more efficient light-harvesting in cryptophyte marine algae.
Calculation of Couplings and Energy-Transfer Pathways between the Pigments of LH2 by the ab Initio Transition Density Cube Method
A practical method for accurate evaluation of the Coulombic contribution to the electronic coupling for energy transfer at any donor−acceptor separation is reported. The method involves the exact…

The description of energy transfer, in particular multichromophoric antenna structures, is shown to vary depending on the spatial and energetic landscape, which dictates the relative coupling strength between constituent pigment molecules.
Lessons from nature about solar light harvesting.
The principles learned from studies of various natural antenna complexes are described and how to elucidate strategies for designing light-harvesting systems are suggested to be used for solar fuel production, to direct and regulate excitation energy flow using molecular organizations that facilitate feedback and control, or to transfer excitons over long distances.

On the Mechanism of Light Harvesting in Photosynthetic Purple Bacteria: B800 to B850 Energy Transfer
The rate of energy transfer from B800 to B850 in the peripheral light harvesting complex LH2 is modeled in detail. A method for determining ensemble average energy transfer rates in complex, coupled…
Excitons in nanoscale systems
A cross-disciplinary review of the essential characteristics of excitons in nanoscience is presented, highlighting the importance of quantum dots, conjugated polymers, carbon nanotubes and photosynthetic light-harvesting antenna complexes.
Electronic Excitation Transfer from Carotenoid to Bacteriochlorophyll in the Purple Bacterium Rhodopseudomonas acidophila
Ultrafast fluorescence upconversion has been used to probe electronic excitation transfer within the B800−B820 light-harvesting antenna of Rhodopseudomonas acidophila strain 7050. Emission from the…
