A novel artificial light-harvesting system (LHS) for the photooxidation reaction was constructed by the phenyl-bis-naphthyl derivative (PBN) and water-soluble phosphate-pillar[5]arene (WPP5). After host-guest interaction, WPP5 integrated with PBN to form WPP5-PBN amphiphiles, which self-assembled to WPP5-PBN nanoparticles. Based on the aggregate state of PBN in WPP5-PBN nanoparticles, WPP5-PBN nanoparticles emitted a significant yellow fluorescence as energy donors. Due to the yellow fluorescence fully covering the absorption of sulforhodamine 101 (SR101), SR101 was used as energy acceptors and loaded in WPP5-PBN nanoparticles for constructing the WPP5-PBN-SR101 LHS, whose energy transfer efficiency and antenna effect were 66.32% and 22.34. Notably, after the energy of the WPP5-PBN antenna transferred to SR101, more singlet oxygen (1O2) production was observed in the WPP5-PBN-SR101 LHS, which was successfully used as a photocatalyst to catalyze the oxidation reaction of 4-methoxythioanisole to 1-methoxy-4-(methylsulfinyl)benzene, imitating the solar energy conversion to chemical energy.

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...
