以溴甲基苏马烯为原料，通过一步反应成功合成了碗形π-共轭苏马烯基三胺。该分子代表具有六个独立五边形的半氮杂富勒烯（C54N6 片段）的示例。其单晶X射线结构分析表明形成了含有氯仿的一维柱状结构。当亲核试剂变为丙二酸二甲酯时，也合成了半富勒烯（C30片段）。
Bowl-shaped π-conjugated sumanenyltriamines were successfully synthesized in a one-step reaction from bromomethylsumanene. This molecule represents an example of hemiazafullerene (C54N6fragment) with six isolated pentagons. Its single-crystal X-ray structural analysis showed the formation of one-dimensional columnar structures incorporating chloroform. The hemifullerene (C30 fragment) was also synthesized when the nucleophile was changed to dimethylmalonate.
