Abstract:
Zn pyro-pheophorbide a and fulleronicotine form in nonpolar solvents a supramolecular self-assembled electron donor-acceptor dyad, which performs fast photoinduced charge separation (0.5 ps) and slow recombination (>1 ns) as evidenced by photochemical studies.

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...

The pigment molecules are arranged across two photosystem domains — the antenna complex and the reaction center. The main aim of the pigment molecules...
