Abstract:
A binuclear ruthenium(II) dimer (BiRD) bridged by an alkene linker was synthesized that was labile to reactive oxygen species generated by another photosensitizer. Compared to the monomeric Ru(II) complex, the BiRD had attenuated fluorescence and singlet oxygen production which could be restored by a longer-wavelength photosensitizer. This two-step amplification strategy demonstrates proof-of-principal for photosensitization chain-reactions.

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...
