Outline of Final Research Achievements

In this study, we have demonstrated development of intelligent nanofibers capable of reacting the dynamic fluid flows generated by the sound of music with an objective to develop a new science which combines chemistry and acoustics. We have newly synthesized sound-responsive supramolecular nanofibers composed of dye molecules containing long alkyl chains and functional groups that allow hydrogen bonding. These nanofibers exhibited sound-induced alignments in a solution with higher response than the previous examples to allow dynamic alignments in harmony with the sound of music. Further, we have succeeded in synthesizing a novel supramolecular ladder polymer, having high linearity and rigidity, from a zinc porphyrin polymer and a bidentate ligand. It has a potential of higher responsiveness for the dynamic fluid flows.
