摘　　要：单壁碳纳米管可以作为纳米尺度的分子容器装填多种分子.结合高分辨透射电子显微镜的原位表征技术,将分子装填进入单壁碳纳米管的内腔中为在原子尺度研究分子的结构和化学性质提供了一种有效的策略.碳纳米管内腔的限域效应往往会驱使装填分子形成一些与体相中完全不同的全新结构,同时也经常会对化学反应的路径产生显著影响.碳纳米管还可以充当模板,影响内腔中化学反应的产物结构.本综述总结了装填分子在碳纳米管内腔中形成的独特结构、碳纳米管内腔中分子的化学反应研究以及装填分子与碳纳米管内壁之间的化学反应.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.
