A light‐triggered shape change of supramolecular nanostructures is achieved through electrostatically self‐assembly of linear polyelectrolytes and oppositely charged dyes in aqueous solution: Upon UV‐irradiation, 1‐µm‐long, flexible cylinders with a cross‐section of 10 nm convert into ellipsoids of 400 nm × 40 nm. The nano‐object shape is encoded in the molecular dye structure.
