Abstract:
Three new supramolecular assemblies SA1-SA3 with different linkages between the photosensitizer and catalyst have been synthesized for light driven water oxidation. With flexible -CH(2)-CH(2)- chains as the linkage, the assembly SA3 displays the best performance for photocatalytic water oxidation compared with the other two assemblies, a turnover number of 34 has been obtained based on the molecular assembly SA3 in a homogeneous system. This type of assembly connected with flexible linkages represents suitable candidates to construct photoanodes for light driven water splitting in dye sensitized photoelectrochemical devices.

Functioning of Photosystems
Photosystems contain many pigment molecules, such as chlorophylls and carotenoids, arranged in a particular organization across two domains — the antenna complex and the reaction center. The main aim of the pigment...

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
