Three different copolymers of C60 -carrying-carbazole and fluorene units with different copolymer composition ratios were designed and synthesized. On the basis of photoluminescence, atomic force microscopy, and Vis-NIR and Raman spectroscopic analysis, we found that these copolymers solubilize only semiconducting single-walled carbon nanotubes (sem-SWNTs) to form copolymer/sem-SWNT hybrids, in which energy transfer from the copolymer/C60 moieties to the SWNTs was revealed. By comparing two possible hybrid structures with molecular-mechanics simulations, the greatest stabilization was found when the C60 moieties lay on the sem-SWNT surfaces.
设计并合成了三种不同的含咔唑和芴单元的C60共聚物，它们具有不同的共聚物组成比例。基于光致发光、原子力显微镜以及可见-近红外和拉曼光谱分析，我们发现这些共聚物仅能溶解半导体单壁碳纳米管（sem-SWNTs）以形成共聚物/sem-SWNT杂化物，其中揭示了从共聚物/C60部分到SWNTs的能量转移。通过分子力学模拟比较两种可能的杂化结构，发现当C60部分位于sem-SWNT表面时稳定性最高。
