Supramolecular materials based on host-guest interactions should exhibit high selectivity and external stimuli-responsiveness. Among various stimuli, redox and photo stimuli are useful for its wide application. An external stimuli-responsive adhesive system between CD host-gels (CD gels) and guest molecules modified glass substrates (guest Sub) is focused. Here, the selective adhesion between host gels and guest substrates where adhesion depends on molecular complementarity is reported. Initially, it is thought that adhesion of a gel material onto a hard material might be difficult unless many guest molecules modified linear polymers immobilize on the surface of hard materials. However, reversible adhesion of the CD gels is observed by dissociating and re-forming inclusion complex in response to redox and photo stimuli.
基于主客体相互作用的超分子材料应具有高选择性和外部刺激响应性。在各种刺激中，氧化还原和光刺激因其广泛应用而备受关注。本文聚焦于一种基于环糊精（CD）主体凝胶与客体分子修饰玻璃基底（客体基底）之间的外部刺激响应性粘附体系。在此，报道了主体凝胶与客体基底之间基于分子互补性的选择性粘附。起初，人们认为凝胶材料很难粘附到硬质材料上，除非有许多修饰了客体分子的线性聚合物固定在硬质材料表面。然而，通过氧化还原和光刺激使包合物解离和重新形成，可观察到CD凝胶的可逆粘附。
