Enhancing hierarchical structural complexities of metal-organic nanocapsules is an effective way of introducing new functions and properties. Herein, we present the synthesis of novel magnesium-seamed C-alkylpyrogallol[4]arene nanocapsules with hierarchical structural complexity via both exterior and endohedral functionalization. The exterior functionalization is realized by using a variety of covalently modified pyrogallol[4]arene ligands, while the endohedral functionalization is achieved via coordination-driven self-assembly. Especially, functionalization of nanocapsule interior by attaching a proline hexad via metal coordination will shed light to the design and synthesis of metal-organic species with heteroligated architectures.
增强金属有机纳米胶囊的层次结构复杂性是引入新功能和特性的有效途径。在此，我们展示了通过外部和内表面功能化合成具有层次结构复杂性的新型镁缝合C-烷基连苯三酚[4]芳烃纳米胶囊。外部功能化通过使用多种共价修饰的连苯三酚[4]芳烃配体来实现，而内表面功能化则通过配位驱动的自组装来实现。特别地，通过金属配位连接脯氨酸六聚体对纳米胶囊内部进行功能化，将为具有杂配位结构的金属有机物种的设计和合成提供思路。
