Functionalization of the interior of hollow microcapsules with polyelectrolytes allows the preparation of supramolecular dye assemblies inside the capsules (see Figure). The dye J-aggregates can be transformed into dye nanocrystals by diffusion of hydrophobic counterions in the capsules, resulting in strong changes of the luminescence behavior.
