One possible route for the development of electronic devices functioning on a molecular length scale is the utilization of photoinduced electron transfer in donor-acceptor (D-A) systems. Debreczeny et al. (p. 584) devised a molecule consisting of covalently bound units in a D-A-A-D sequence and show that photogeneration of ion pairs in the first unit leads to the generation of local electric fields that can be used to control a second photoinduced electron transfer reaction within the same molecule.
