An approachc ombining DNAn anoscaffolds with supramolecular polymers for the efficient and directional propagation of light-harvesting cascades has been developed. As eries of photonic wires with different arrangements of fluorophores in DNA-organized nanostructures were linked to light-harvesting supramolecular phenanthrene polymers (SPs) in as elf-assembled fashion. Among them, al ight-harvesting complex (LHC) composed of SPs and ap hotonic wire of phenanthrene,C y3, Cy5, and Cy5.5 chromophores reveals ar emarkable energy transfer efficiency of 59 %. Stepwise transfer of the excitation energy collected by the light-harvesting SPs via the intermediate Cy3 and Cy5 chromophores to the final Cy5.5 acceptor proceeds through aF çrster resonance energy transfer mechanism. In addition, the light-harvesting properties are documented by antenna effects ranging from 1.4 up to 23 for different LHCs.
