Light controls size: A novel type of self-organized supramolecular nanoparticles can change their size upon irradiation with UV light (see picture). The doubly responsive system combines a light-triggered size with a pH-induced switching between nanoscale aggregates and molecular building blocks. The nano-objects form by a combination of ionic and π–π interactions between macro-ions and dye ions.

- 10Disassembling by increasing pH and carrying out spectroscopic investigations prior to re-isomerization allowed UV/Vis data to be analyzed without a scattering contribution.
- 11AFM diameters given are measured at the surface but half widths that are much smaller are the basis for a volume comparison with DLS. Based on this, the volume change upon irradiation is in the same order of magnitude.
- 12The change is not due to the size change, as the particle size increases upon irradiation.
- 13This is evident from UV/Vis measurements.
- 14Furthermore, because the cis/trans ratio for free and bound dye differs, there may be a readjustment in the equilibrium between trans dye in the assembly and in solution.
