摘要：通过Sonogashira偶联反应制备了设计结构的烯二炔化合物,以单分散SiO2无机纳米粒子为模板,以设计结构的烯二炔化合物为功能化前驱体,在无机纳米粒子表面通过分子自组装形成单分子层,并经原位引发Bergman环化反应形成聚芳烃交联网状结构,刻蚀除去无机模板后得到了均一形貌的富碳纳米胶囊。
The enediyne utilized in the templated synthesis of carbon nanocapsules was synthesized through Sonogashira coupling reaction.Monodispersed silica nanoparticles were chosen as the template.Self-assembled monolayers of enediyne compounds were formed by attaching enediyne onto silica nanoparticles.Subsequent Bergman cyclization of enediyne compounds in situ gave highly crosslinked polyarene networks on the surface of silica nanoparticles.After removal of template,uniform hollow carbon enriched nanocapsules were obtained and characterized with a variety of techniques.
