Shedding light on DNA : A DNA‐based light‐harvesting antenna has been synthesized. Light is absorbed by π‐stacked phenanthrene units and efficiently transferred to a phenanthrene–pyrene exciplex. The whole system is structurally organized by a DNA scaffold. Up to eight phenanthrene units are used for light collection and the intensity of the exciplex emission is proportional to the number of light‐absorbing chromophores.
