基于主客体相互作用的超分子材料应表现出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的应用而有用。重点关注CD主体凝胶（CD凝胶）和客体分子改性玻璃基板（客体Sub）之间的外部刺激响应粘合系统。在这里，报告了主体凝胶和客体基质之间的选择性粘附，其中粘附取决于分子互补性。最初，人们认为凝胶材料粘附到硬质材料上可能很困难，除非许多客体分子改性的线性聚合物固定在硬质材料的表面上。然而，通过响应氧化还原和光刺激解离和重新形成包合物，观察到 CD 凝胶的可逆粘附。
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.
