Herein we report a facile three-step synthesis of [8]-, [9]-, and [12]cyclo-1,4-naphthalene nanorings as the conjugated segments of carbon nanotubes. The nanorings were created via a platinum-mediated assembly of 1,4-naphthalene-based units and subsequent reductive elimination in the presence of triphenylphosphine. This present platinum-mediated approach is attractive because of its simple three-step process to produce the targeted nanorings in a high overall yield. In addition, their photophysical properties were studied using UV-vis spectroscopy and photoluminescence (PL) spectroscopy, which further revealed their unique size-dependent properties.
在此，我们报道了一种简便的三步合成方法，用于制备作为碳纳米管共轭片段的[8] -、[9] - 和[12] - 环 - 1,4 - 萘纳米环。这些纳米环是通过铂介导的基于1,4 - 萘单元的组装以及随后在三苯基膦存在下的还原消除反应制备而成。这种当前的铂介导方法具有吸引力，因为其简单的三步过程能够以较高的总产率制备出目标纳米环。此外，我们使用紫外 - 可见光谱和光致发光（PL）光谱对它们的光物理性质进行了研究，这进一步揭示了它们独特的尺寸依赖性性质。
