Creation and functional development of stress-responsive supramolecular materials

环糊精（CD）具有分子识别、水解催化活性、聚合活性等诸多诱人的功能。本文着重介绍了利用聚合物侧链间的相互作用构建新型刺激响应性超分子材料。 首先，通过主客体相互作用成功制备了刺激响应型溶胶-凝胶开关材料。 偶氮苯和二茂铁衍生物被选为光和氧化还原响应分子，分别。通过主客体相互作用，获得了具有氧化还原响应和自修复功能的超分子材料。 此外，另一种具有CD包合物的自修复材料显示出对切割表面的选择性自修复特性。 具有刺激响应性基团的化学交联水凝胶在外部刺激下表现出弯曲行为，这控制了作为交联剂的函数的包合物的比例。

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.
