Abstract

Photonic wires were constructed by sequentially arranging up to 7 fluorophores along a concatenated DNA scaffold. This yielded nanostructures displaying from one- to six-energy transfer steps where end-to-end efficiency reflected the multiple underlying photophysical processes and the ability of long-range interactions to compensate for localized non-ideal dye behaviour.
