The ability to control supramolecular and macroscopic self-assembly and disassembly holds great potential for responsive, reversible adhesives that can efficiently broker stresses accumulated between two surfaces. Here, cucurbit[8]uril is used to directly adhere two functionalized mica substrates creating surface-surface interactions that are held together through photoreversible CB[8] heteroternary complexes. Comparison of single-molecule, bulk, and macroscopic adhesion behavior give insight into cooperativity and stress dissipation in dynamic adhesive systems.
能够控制超分子和宏观自组装和拆卸对于响应性、可重复使用的粘合剂具有很大的潜力，这种粘合剂可以有效地缓解两个表面之间积累的应力。在这里，使用葫芦[8]脲直接将两个功能化云母基底粘合在一起，形成通过光致可逆 CB[8]杂三元配合物结合在一起的表面-表面相互作用。对单分子、体相和宏观粘附行为的比较提供了对动态粘附系统中协同作用和应力耗散的深入了解。
