Synthetic DNA hairpins possessing a Michler’s ketone linker at one end separated from a perylenediimide base surrogate by four base pairs were designed to investigate transport of charge between the two chromophores. Pulsed laser excitation of Michler’s ketone with 400 nm light results in formation of a charge transfer excited state which returns to the group state without undergoing electron transport to perylenediimide (upper pathway). Excitation of perylenediimide with 545 nm light results in injection of a positive charge which is transported via the base pairs to Michler’s ketone (lower pathway). For details see the paper “Electronic Interactions of Michler’s Ketone with DNA Bases in Synthetic Hairpins” by Almaz S. Jalilov et al. on pages 739-747 in this issue.
