One tetrahedral and two trigonal prismatic cages with π-basic Au(pyrazolate) faces were obtained by connection of pre-formed gold complexes dynamic covalent imine chemistry. The parallel arrangement of the Au(pyrazolate) complexes in the prismatic cages augments the interaction with π-acids, as demonstrated by the encapsulation of polyhalogenated aromatic compounds. The tetrahedral cage was found to act as a potent receptor for fullerenes. The structures of the three cages, as well as the structures of adducts with C and C, could be established by X-ray crystallography.
通过预形成的金配合物的动态共价亚胺化学连接，得到了一个具有π-碱性金（吡唑酸盐）面的四面体笼和两个三角棱柱笼。棱柱笼中Au（吡唑酸盐）配合物的平行排列增强了与π-酸的相互作用，多卤代芳香化合物的包封证明了这一点。发现四面体笼可作为富勒烯的有效受体。通过X射线晶体学可以确定这三个笼的结构以及与C和C加合物的结构。
