Mimicking the antenna-electron transfer properties of photosynthesis.

چکیده
A molecular assembly based on derivatized polystyrene is described, which mimics both the light-harvesting and energy-conversion steps of photosynthesis. The system is unique in that the two key parts of a photosynthetic system are incorporated in a functional assembly constructed from polypyridine complexes of Ru(II). This system is truly artificial, as none of the components used in construction of the assembly are present in a natural photosynthetic system. Quantitative evaluation of the energy and electron transfer dynamics after transient irradiation by visible light offers important insights into the mechanisms of energy transport and electron transfer that lead to photosynthetic light-to-chemical energy conversion.

Mimicking bacterial photosynthesis
Photosynthesis in bacteria involves absorption of light by antenna chromophores and transfer of excitation to reaction centers, which convert the excitation energy to electrochemical potential energy in the form of transmembrane charge separation. A proton pump uses this stored energy to generate proton motive force across the membrane, which in turn is used to synthesize adenosine triphosphate...
متن کاملCombining light-harvesting and charge separation in a self-assembled artificial photosynthetic system based on perylenediimide chromophores.
Self-assembly of robust perylenediimide chromophores is used to produce an artificial light-harvesting antenna structure that in turn induces self-assembly of a functional special pair that undergoes ultrafast, quantitative charge separation. The structure consists of four 1,7-(3',5'-di-tert-butylphenoxy)perylene-3,4:9,10-perylene-3,4:9,10-bis(carboximide) (PDI) molecules attached to a single 1...
متن کاملMultiple Impacts of Loss of Plastidic Phosphatidylglycerol Biosynthesis on Photosynthesis during Seedling Growth of Arabidopsis
Phosphatidylglycerol (PG) is the only major phospholipid in the thylakoid membrane in cyanobacteria and plant chloroplasts. Although PG accounts only for ~10% of total thylakoid lipids, it plays indispensable roles in oxygenic photosynthesis. In contrast to the comprehensive analyses of PG-deprived mutants in cyanobacteria, in vivo roles of PG in photosynthesis during plant growth remain elusiv...
متن کاملEnergy transfer and trapping in photosystem I.
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 this energy to a reaction centre (RC) site where the energy is `trapped' by means of a stable charge separation. Photosystem (PS) I is one of two such photosystems in oxygenic photosynthesis. When co-operating with PS...
متن کاملMimicking Photosynthesis with Electrode-Supported Lipid Nanoassemblies.
The grand scale, ultimate efficiency, and sustainability of natural photosynthesis have inspired generations of researchers in biomimetic light energy utilization. As an essential and ubiquitous component in all photosynthetic machinery, lipids and their assemblies have long been recognized as powerful molecular scaffolds in building artificial photosynthetic systems. Model lipid bilayers, such...
