Photonic wires were constructed by sequentially arranging up to 3 fluorophores along a DNA scaffold with attached supramolecular phenanthrene polymers. This efficient light harvesting supramolecular polymers are formed through the assembly of short DNA and non-DNA amphiphilic oligomers in water. This yielded in creation of DNA-based photonic wires polymers with the capacity to harvest and transfer excitation energy. Förster resonance energy transfer (FRET) cascades conjugated to the phenanthrene harvesting antenna are presented as an efficient system for developing nanostructured photonic systems.
