Outline of Final Research Achievements

In this study, we have demonstrated syntheses of intelligent nanofibers capable of switching their properties in response to the two physical stimuli, sound and light, with an objective to develop nanoscale molecular machines. We have newly synthesized sound/photo-responsive supramolecular nanofibers composed of an azobenzene derivative (AZ) and a dithienylethene derivative (DTE). These nanofibers exhibited sound-induced alignments in the solutions. We found that AZ and DTE nanofibers exhibit ON-OFF switching and wavelength switching, respectively, of the sound induced linear dichroism with UV and visible light.
