Amphiphilic compounds with oligo(ethylene glycol) unit form self‐assembled architectures and exhibit lower critical solution temperature (LCST) behavior. Amphiphilic diarylethenes with ester and amide linker are reported. These compounds formed micrometer‐sized supramolecular assemblies in water, and these assemblies exhibited reversible photoinduced macroscopic morphological transformation. The morphological transformation is understood as the photoinduced phase transition between the high‐ and low‐temperature phases of LCST transition. These results open the way of design of phototransformative supramolecular assembly. More information can be found in the Full Paper by K. Higashiguchi, K. Matsuda et al. on page 15059.
