尽管其独特的结构、诱人的性质以及在碳纳米科学和技术中的潜在应用，但之字形碳氢化合物纳米带的合成和功能化直到最近才得到很大程度的探索。本文报道了带[4]芳烃[4]tropilides的选择性转化及其在新型带构造中的应用。在可控条件下，苯乙烯酸酐氧化带[4]芳烃[4]tropidene，选择性地得到单至四烷基（α-二酮）功能化带中间体。随后与1,2-苯二乙腈和1,2-苯二胺发生缩合反应，产生了具有各种大环腔的前所未有的多种带。
Despite their unique structures, tantalizing properties, and potential applications in carbon nanoscience and technology, the synthesis and functionalization of zigzag hydrocarbon nanobelts have remained largely unexplored until recently. Reported herein is the selective transformations of belt[4]arene[4]tropilidenes and their application in the construction of novel belts. The oxidation of belt[4]arene[4]tropilidene with benzeneseleninic anhydride under controlled conditions selectively afforded mono- to tetrakis(α-diketone)-functionalized belt intermediates. A subsequent condensation reaction with 1,2-phenylenediacetonitrile and 1,2-phenylenediamine produced a diversity of unprecedented belts with various macrocyclic cavities.
