Octatrimethylsilyl-[8]cycloparaphenylene ([8]CPP-8TMS) was synthesized using the copper(I)-mediated homocoupling reaction of the highly functionalized biphenyl precursor and subsequent platinum-mediated macrocyclization. [8]CPP-8TMS was well characterized by spectroscopic techniques, including NMR, mass, UV-vis absorption, and fluorescence spectroscopy and cyclic voltammetry. Single-crystal X-ray diffraction analysis indicates that [8]CPP-8TMS possesses a highly symmetric structure and adopts an intermolecular tubular packing. [8]CPP-8TMS can serve as a versatile platform for the efficient construction of unprecedented functional nanocarbon structures.
八三甲基硅烷基-[8]环对亚苯基([8]CPP-8TMS)是通过高官能化联苯前体的铜(I)介导的自偶联反应以及随后的铂介导的大环化反应合成的。[8]CPP-8TMS通过多种光谱技术得到了充分表征,包括核磁共振、质谱、紫外可见吸收光谱、荧光光谱和循环伏安法。单晶X射线衍射分析表明,[8]CPP-8TMS具有高度对称的结构,并采用分子间管状堆积。[8]CPP-8TMS可以作为一个通用平台,用于高效构建前所未有的功能性纳米碳结构。
