Abstract

(Figure Presented) A change of direction: The intensity and direction of photocurrents in photosensitizer-electron acceptor dyads anchored to electrodes is controlled by the orientation and composition of the subunits. DNA templates attached to electrode surfaces act as scaffolds for the assembly of the dyads, which comprise either CdS nanoparticles or ruthenium(II) polypyridyl complexes in conjunction with viologen units that act as relays (see picture).
