An approach combining DNA nanoscaffolds [1,2] with supramolecular polymers [3] for the efficient and directional propagation of light-harvesting cascades has been developed. A series of photonic wires with different arrangements of fluorophores in DNA-organized nanostructures were linked to light-harvesting supramolecular phenanthrene polymers (SPs) in a self-assembled fashion. Among them, a light harvesting complex (LHC) composed of SPs and a photonic wire of phenanthrene, Cy3, Cy5 and Cy5.5 chromophores reveals a remarkable energy transfer efficiency of 59%. [1] K.
