Abstract

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.
