Supramolecular structures of organic molecules on planar nanocarbon surfaces, such as highly oriented pyrolytic graphite (HOPG), have been extensively studied and the factors that control them are generally well‐established. In contrast, the properties of supramolecular structures on curved nanocarbon surfaces like carbon nanotubes remain challenging to predict and/or to understand. This paper reports an investigation into the first study of the supramolecular structures of 5,15‐bisdodecylporphyrin (C12P) on chiral, concentrated single‐walled carbon nanotubes (SWNTs; with right‐handed helix P‐ and left‐handed helix M‐) surfaces using STM. Furthermore, the study is the first of its kind to experimentally assign the absolute‐handedness chirality of SWNTs, as well as to understand their effect on the supramolecular structures of organic molecules on their surfaces. Interestingly, these SWNT enantiomers resulted in supramolecular structures of opposite chirality based on the handedness chirality. With molecular modelling, we predicted the absolute‐handedness chirality of SWNTs, before demonstrating this experimentally.

使用有机分子超分子结构分配单壁碳纳米管的绝对手性

平面纳米碳表面上的有机分子的超分子结构，例如高度取向的热解石墨（HOPG），已经得到了广泛的研究，而控制它们的因素通常也已被很好地确立。相反，弯曲的纳米碳表面如碳纳米管上的超分子结构的性质仍然难以预测和/或理解。本文报道了对5,15-双十二烷基卟啉（C12P）在手性浓缩单壁碳纳米管（SWNTs）上的超分子结构的首次研究;右手螺旋P和左手螺旋M‐）使用STM的表面。此外，这项研究是首次通过实验确定单壁碳纳米管的绝对手性，并了解其对表面有机分子超分子结构的影响。有趣的是，基于手性手性，这些SWNT对映异构体产生相反手性的超分子结构。通过分子建模，我们在实验演示之前预测了单壁碳纳米管的绝对手性。
