Abstract:
C60-styryl Bodipy dyads that show strong absorption of visible light (ε = 64,600 M(-1) cm(-1) at 657 nm) and a long-lived triplet excited state (τT = 123.2 μs) are prepared. The dyads were used as heavy-atom-free organic triplet photosensitizers for photooxidation of 1,5-dihydroxynaphthalene via the photosensitizing of singlet oxygen ((1)O2). The photooxidation efficiency of the dyads compared to the conventional Ir(III) complex (1)O2 photosensitizer increased 19-fold.

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...
