None:
Two mononuclear Ir(I)-corrorin complexes, FPh-Ir and Py-Ir, featuring peripheral κ2-N,N' dipyrrin coordination, were structurally characterized and shown to efficiently photosensitize singlet oxygen under green light (ΦΔ = 0.65-0.69 in CH3CN). TD-DFT supports a near-resonant S1 → T3 intersystem-crossing pathway with appreciable spin-orbit coupling.

The Photochemical Reaction Center
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...
