Light‐responsive vesicles : Derivatives of an α‐amino acid with two azobenzene side chains self‐assemble into vesicular structures that undergo morphological transitions upon light irradiation (see scheme). This is the first example of photoresponsive vesicle‐like supramolecular structures formed exclusively by peptides or derivatized amino acids. The entrapment and subsequent light‐induced release of functionalized gold nanoparticles are also shown.
