Combining chemically different building blocks in supramolecular nanoparticles is a promising key to tailored structures and functionalities. π–π heterostacks of dye molecules form upon electrostatic self‐assembly with a polyelectrolyte, resulting in stable ternary nano‐assemblies in aqueous solution. Core‐shell spheres, cylinders, and flexible cylinders result, which exhibit new shapes different from the binary systems. Particle shapes can be tuned through the dye composition.
