项目摘要

This project aims at the synthesis of unprecedented chiral carbon nanobelt molecule that could be the next generation nanocarbon material, and subsequently investigate their host guest chemistry with fullerenes, templated carbon nanotube growth and other material related applications. The first stage of the project is to synthesize the target molecule. So far, the synthesis was conducted smoothly and the key diborylated intermediate was obtained by a five-step transformation in good yield from commercially available compound. The key transformation, a platinum mediated macrocylization reaction, is currently being examined. To overcome the steric hindrance of the ortho-substituted substrate, we are now screening reaction conditions with different solvent, base and ligand. Also the reaction temperature and time will be optimized. At the same time, using an alternative synthetic approach, a new carbon nanobelt molecule has been successfully synthesized and the structure was unambiguously confirmed by NMR, MALDI-TOF MS and X-ray single crystal analysis. With the new synthetic strategy, we successfully prepared a series of carbon nanobelt molecules and studied their physical properties.

该项目旨在合成前所未有的手性碳纳米分子，该分子可能是下一代纳米碳材料，随后使用富勒烯，模板碳纳米管的生长和其他材料相关的应用来研究其宿主宾客化学。该项目的第一阶段是合成目标分子。到目前为止，通过五步转换从市售化合物中以良好的产量获得了五步转化，从而平稳地进行了合成，并获得了关键的二型中间体。目前正在研究关键转化，一种铂介导的大型聚合反应。为了克服矫正基底物的空间障碍，我们现在正在用不同的溶剂，碱和配体筛选反应条件。另外，反应温度和时间将被优化。同时，使用替代合成方法，已成功合成了一种新的碳纳米分子，并通过NMR，MALDI-TOF MS和X射线单晶体分析明确确认了结构。通过新的合成策略，我们成功地制定了一系列碳纳米生物分子并研究了它们的物理特性。
