摘要：
The dynamics of reversible photoinduced electron transfer in individual perylene-diimide-triphenylamine-based donor-acceptor dendrimers immobilized in polystyrene were investigated by single-molecule spectroscopy. By changing the local concentration of oxygen, it was possible to influence the transition of the charge-separation state (CSS) either to the locally excited state (LES) or to the ground state (CS, see graphic).
