Carbon nanobelts that consist of a loop of fully fused benzene rings are long-standing and challenging targets of organic synthesis and are key steps toward the ultimate synthesis of uniform carbon nanotubes (CNTs) of single chirality and predefined diameter. Herein, we report the synthesis of an unprecedented armchair carbon nanobelt and the first chiral carbon nanobelt, which represent sidewall segments
由完全稠合的苯环环组成的碳纳米带是有机合成的长期目标和挑战性目标,并且是最终实现单一手性和预定直径的均匀碳纳米管(CNT)最终合成的关键步骤。在这里,我们报告了空前的扶手椅碳纳米带和第一个手性碳纳米带的合成,它们分别代表扶手椅和手性CNT的侧壁部分,分别是(12,12)CNT和(18,12)CNT。这些碳纳米带是通过Scholl反应,通过相应的聚芳基化碳纳米环的π扩展,由2,5-二(苄氧基)-1,4-苯醌分六步合成的。扫描隧道显微镜显示这些纳米带是大小均一的纳米颗粒。
