title: Bidirectional electron transfer in molecular tetrads.
abstract: Two-color excitation of a molecular tetrad leads to directed electron transfer in opposite directions along the molecular axis according to which chromophore is illuminated and gives a 40,000-fold disparity in the lifetimes of the resultant charge-separated states.
