| Research Abstract |
Cyclodextrins (CDs) have a lot of attractive functions, molecular recognition, hydrolysis catalytic activity, polymerization activity, etc. The author focus on the construction of innovative stimuli responsive supramolecular materials using the interaction between polymer side chains. First, stimuli-responsive sol-gel switching materials were successfully prepared through host-guest interactions. Azobenzene and ferrocene derivatives were chosen as photo and redox-responsive molecules, respectively. The author obtained supramolecular materials with redox-responsive and self-healing properties caused by host-guest interaction. Furthermore, another self-healing material with CD inclusion complexes showed selective self-healing properties for cut-surfaces. The chemical crosslinked hydrogel with stimuli-responsive groups showed the bending behavior by external stimuli, which controlled the ratio of inclusion complexes as a function of crosslinkers.
