摘要

Molecular container compounds have a range of potential applications in chemical and biological sciences,most notably as nanoreactors,drug delivery devices,and storage materials.We report a highly efficient dynamic covalent chemistry approach for the synthesis of covalent rhombicuboctahedral nanocapsule 1 from 14 square-and triangular-shaped molecu- lar components.The nanocapsule is obtained in a one-pot reaction in high yield and high purity,and has a solvo- dynamic diameter of 3.9 nm.In our approach,six formyl cavitands and eight 1,3,5-tris(p-aminophenyl)benzene molecules are assembled into a molecular rhombicuboctahedron through twenty four newly formed dynamic imine bonds.Binding studies show that 1 encapsulates tetraalkylammonium salts in toluene.We also discuss the growth mechanism of this nanocapsule.
