Webb1 jan. 2012 · When excited by a photon of light, an antenna chlorophyll will rapidly pass on the excitation to one of the adjacent chlorophylls to which it is electronically coupled. The excitation can visit a large number of chlorophylls during the lifetime of the excited state (the fluorescence lifetime for chlorophyll is 5 ns [1] ). Webbarrays. Upon photoexcitation with visible light (638 nm), the π-stacked arrays accept an electron from a sacrificial electron donor placed outside of the vesicular spheres. The array then rapidly transports the acquired electron into the vesicles, which contain an electron-accepting quinone derivative.
