Macrocyclic receptors having extreme thermo-oxidative stability, and which bind a wide range of electron-donor substrates via pi-stacking donor-acceptor interactions, are accessible by cycloimidization of an amine-functionalized aryl ether-sulfone with pyromellitic dianhydride or 1,4,5,8-naphthalenetetracarboxylic dianhydride. The potential of these receptors in supramolecular chemistry is illustrated, for example, by the spontaneous self-assembly and crystallization of a five-component [3]pseudorotaxane from a solution of its constituents.
具有极高热氧化稳定性的大环受体，其通过π-堆积供体-受体相互作用结合多种电子供体底物，可通过胺官能化的芳基醚砜与均苯四甲酸二酐或1,4,5,8-萘四甲酸二酐的环酰亚胺化反应来制备。例如，由其组分的溶液自发自组装并结晶形成五组分[3]准轮烷，说明了这些受体在超分子化学中的潜力。
