超分子化学和界面的结合有效地促进了超分子化学和胶体与界面科学的发展。刺激响应性超分子界面,因在外界刺激作用下能够引起界面物理化学性质的改变并带来新的界面功能,而受到广泛的关注。近年来,溶液中基于偶氮苯-环糊精主客体相互作用的超分子组装体已经得到了广泛的研究。我们将溶液中基于偶氮苯-环糊精主客体作用的可控可逆超分子组装体转移到界面上,构筑了具有刺激响应性的功能化超分子界面,并实现了表面浸润性的可逆调控、生物大分子的可控吸附与脱附、光可控的生物电化学催化等功能。我们期待类似的概念可以拓展到其他超分子体系,构筑具有特定结构的功能界面。
The combination of supramolecular chemistry and interface effectively promoted the development of supramolecular chemistry and colloid and interface science. Stimuli responsive supramolecular interface, due to the impact of external stimuli can cause changes in the interface physical and chemical properties and bring new interface features, and has received widespread attention. In recent years, supramolecular assemblies based on azo-benzene-cyclodextrin interaction in solution have been extensively studied. We transfer the controllable and reversible supramolecular assembly based on the interaction between host and guest of azobenzene-cyclodextrin in the solution to the interface, and construct a functional supramolecular interface with stimuli responsiveness and achieve the reversible regulation of surface infiltration , Controllable adsorption and desorption of biological macromolecules, light controllable bio-electrochemical catalysis and other functions. We look forward to a similar concept can be extended to other supramolecular systems, to build a functional interface with a specific structure.
