摘　　要：近年来,通过有机合成方式构建的结构精确的纳米碳材料备受关注,展现出独特的性质和广阔的应用前景.将具有螺旋手性的螺烯与大尺寸的分子基纳米碳结合,产生了一类独特的手性纳米碳分子,在手性光学、手性光电子学及自旋电子学等领域具有潜在的应用价值.然而,由于其特殊的螺旋结构及分子内较大的张力,这类纳米碳分子的合成颇具挑战.在合成螺烯类纳米碳分子的几类常用方法中,Scholl反应条件温和且十分高效,被广泛使用.从合成的角度出发,详细综述了通过Scholl反应构建螺烯类纳米碳分子的研究进展,并对该领域未来的发展提出展望.Molecular nanocarbon materials with well-defined structures constructed through organic synthesis have attracted much attention in recent years,exhibiting unique properties and broad applications in many areas.The combination of helicenes and molcular nanocarbons generates a fancinating type of chiral molecular nanocarbons with potential applications in the fields of chiral optics,chiral optoelectronics and spintronics etc.However,it is of greart challenge to synthesize these molecules due to the large intramolecular strain and the special helical structure.Among various synthetic strategies,the Scholl reaction possesses the advantages of mild conditions and high efficiency.In this review,recent advances in the syntheses of helicene-based molecular nanocarbons via the Scholl reaction are summarized,and our perspectives to stimulate further development of the chiral nanocarbon materials are also provided.
