通过开发模块化合成路线，设计并合成了包含圆柱形核心和十字形边缘的 3 纳米分子。通过使用先前研究的环状前体作为起始材料，在有缺陷的圆柱体的边缘安装了多个咔唑单元。有缺陷的圆柱体合成掺杂了两种类型的氮原子，即吡啶氮原子和吡咯氮原子，通过电荷转移相互作用导致荧光中的溶剂化变色。晶体学分析充分揭示了 C552H496N24 大分子的结构，并揭示了晶体中氮掺杂圆柱体的独特螺旋排列。
A 3‐nm molecule comprising a cylindrical core and cross‐shaped rims was designed and synthesized by developing a modular synthetic route. By using a cyclic precursor from previous studies as a starting material, multiple carbazole units were installed at the rims of the defective cylinder. The defective cylinder was synthetically doped with two types of nitrogen atoms, that is, pyridinic and pyrrolic nitrogen atoms, which resulted in solvatochromic shifts in fluorescence by charge‐transfer interactions. The structure of the large, C552H496N24molecule was fully disclosed by crystallographic analyses, and the unique helical arrangement of nitrogen‐doped cylinders in the crystal was revealed.
