Multiply charged dye molecules can be precipitated from water by complexation with oppositely charged surfactants. It is shown that this complex formation occurs with 1:1 stoichiometry in a highly cooperative fashion. The resulting solids show either a gel‐like or a supramolecular fibrillar morphology with a very high degree of order on the nanoscale, as evidenced by small‐angle X‐ray scattering and pleochroic behavior under plane‐polarized light.
