Novel magnesium-seamed organic nanocapsules with hierarchical structural complexity

Abstract

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.
