19.4 Conclusion
In this chapter, we discussed photoinduced morphological changes and photodriven
movement of objects based on the photoresponsive supramolecular architectures
composed of amphiphilic diarylethene. The supramolecular architectures induced
LCST transition upon photoirradiation and exhibited micrometer-sized morphological changes under an optical microscope which originated from the differences
in nanometer-sized structures. The morphological changes can be controlled by
modifying the intermolecular interactions, e.g., by changing the linker moiety. The
nanofibers were bundled by the application of a depletion force and the bundle showed
submillimeter-sized shrinking. The nanofibers were orientated by linearly polarized
