展示了一种通过加热过程合成掺杂共轭分子的简便方法。通过气相反应将溴封端的三噻吩前体封装在单壁碳纳米管中，额外的热处理促进了前体的热缩合。透射电子显微镜观察和光学测量表明，六噻吩的成功合成及其通过缩合反应产生的 Br 掺杂剂的掺杂（氧化）。这项研究为仅通过加热过程从单种分子合成掺杂共轭聚合物提供了一种新策略。
A facile synthetic method for doped conjugated molecules by a heating process is demonstrated. Br-terminated terthiophene precursors are encapsulated in single-walled carbon nanotubes by a vapor-phase reaction, and additional heat treatment promotes the thermal condensation of the precursors. Transmission electron microscopy observations and optical measurements show the successful synthesis of sexithiophenes and their doping (oxidation) by Br dopants generated by the condensation reaction. This study provides a new strategy for the synthesis of the doped conjugated polymers from single-species molecules by only a heating process.
