Popis:	A prototype molecular switch is demonstrated that works on the principle that the local electric field produced by one photogenerated ion pair (D1+-A1−) can influence the rate constants for photoinduced electron transfer and recombination in a second donor-acceptor pair (A2-D2). Two ultrafast laser pulses were used to control the rate of a photoinduced electron transfer reaction within a molecule that consists of two covalently linked electron donor-acceptor pairs fixed in a linear structure, D1-A1-A2-D2. This type of molecular architecture may lead to the development of electronic devices that function on the molecular length scale.
