摘　　要：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 with interfaces enhances the development of supramolecular chemistry as well as colloid and interface science. Supramolecular chemistry at interfaces allows for the construction of various smart and soft surfaces that can adapt to environmental changes, such as biomimetic surfaces and self-cleaning surfaces. In this article, we discuss strategies for the transfer of supramolecular complexes of azobenzene and cyclodextrin from solution to surfaces for the fabrication of stimuli-responsive surfaces with novel interfacial functions including tunable surface wettability, reversible protein adsorption and resistance, and photo-switchable bioelectrocatalysis. It is anticipated that these concepts can be extended to other supramolecular systems in order to engineer functional surfaces with designed structures and functions.
