Photosynthetically active membranes of certain bacteria and higher plants contain antenna
systems which surround the reaction center to increase its absorption cross section for the …

The primary processes in all photosynthetic systems involve the absorption of energy from
(sun) light by chromophores in a light harvesting antenna, and the subsequent transfer of …

Excitons are considered as the basic concept used by describing the spectral properties of
photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light …

Quantum states depend on the coordinates of all their constituent particles, with essential
multi-particle correlations. Time-resolved laser spectroscopy is widely used to probe the …

We describe a method to measure ultrafast protein structural changes using time-resolved
wide-angle X-ray scattering at an X-ray free-electron laser. We demonstrated this approach …

We report on two multi-chromophore building blocks that self-assemble in solution and on
surfaces into supramolecular light-harvesting arrays. Each building block is based on …

Since highly symmetric cyclic architecture of light-harvesting antenna complex LH2 in purple
bacteria was revealed in 1995, there has been a renaissance in developing cyclic porphyrin …

Abstract Photosystem I (PS-I) contains a small fraction of chlorophylls (Chls) that absorb at
wavelengths longer than the primary electron donor P700. The total number of these long …

Ultrafast carrier dynamics in individual semiconducting single-walled carbon nanotubes was
studied by femtosecond transient absorption and fluorescence measurements. After …

Singlet–singlet annihilation experiments have been performed on trimeric and aggregated
light-harvesting complex II (LHCII) using picosecond spectroscopy to study spatial …
