由二苯甲酮 - 3,3′,4,4′ - 四羧酸二酐和1,3 - 金刚烷二甲胺以37%的产率合成了一种具有二苯甲酮 - 3,3′,4,4′ - 四羧酸二酰亚胺和金刚烷单元的大环化合物（1）。化合物1和1,4 - 二氧六环（a）在氯仿中结晶形成包合物晶体（1a），1、氯仿和a的化学计量比为1∶2∶1。在晶态下，主体分子排列形成具有一维通道的网络结构，其中两种不同的客体分子通过C - H⋯O和C - H⋯Cl相互作用共同容纳在其中。在相同条件下获得了含有环醚（b - d）且化学计量比相同的包合物晶体。在所有包合物晶体中，1的形状、构象及其排列与晶体1a相似，并且对液态客体的分子结构进行了表征。
A macrocycle having benzophenone-3,3′,4,4′-tetracarboxylic diimide and adamantane units (1) was synthesized from benzophenone-3,3′,4,4′-tetracarboxylic dianhydride and 1,3-adamantanedimethanamine in 37% yield. The crystallization of 1 and 1,4-dioxane (a) in chloroform resulted in the formation of inclusion crystal (1a), and the stoichiometric ratio of 1, chloroform, and a was 1 : 2 : 1. The host molecules were arranged to afford network structures with one-dimensional channels in the crystalline state, in which two different guest molecules were jointly accommodated through CH⋯O and CH⋯Cl interactions. Inclusion crystals containing cyclic ethers (b–d) with the same stoichiometric ratio were obtained under identical conditions. In all of the inclusion crystals, the shape and conformation of 1 and their arrangements were similar to those of crystal 1a, and the molecular structures of the liquid guests were characterized.
