interactions were found to greatly influence the temperature-dependent dynamic behavior within supramolecularassemblies. Using an amphiphilic dendron, we systematically changed the hydrophobic groups introducing increasing levels of aromaticity while keeping the hydrophilic part constant. We show that the supramolecularassemblies become less sensitive to temperature changes when aromatic interactions in

on micellar aggregates and the consequential guest release. The release of the guest molecule is conveniently tuned by stabilizing the micellar aggregates throughphotochemicalcrosslinking of hydrophobic coumarin units. This photo‐crosslinking is also utilized as a tool to investigate the mode of enzyme–substrate interaction in the context of aggregate–monomer equilibrium.
