单壁碳纳米管内腔中的分子行为

Single-walled carbon nanotubes can be used as nano-scale molecular containers to encapsulate a variety of molecules. Combined with the in-situ high-resolution transmission electron microscopy, molecules encapsulation of single-walled carbon nanotubes provides a powerful strategy for studying the structure and chemical properties of molecules at the atomic scale. The confinement effect of the inner cavity of carbon nanotubes often drives the encapsulated molecules to form new structures that are completely different from those in the bulk phase. At the same time, it also often has a significant impact on the pathways of chemical reactions. Carbon nanotubes can also act as a template, affecting the structure of the product of the chemical reaction in the inner cavity. In this review, we summarized the unique structure formed by the encapsulated molecules in single-walled carbon nanotubes, the research on the chemical reactions of the encapsulated molecules, and the chemical reactions between the encapsulated molecules and the inner walls of the carbon nanotubes.
