摘要采用“自下而上”的方法实现了原子精密多环芳烃(PAHs)和石墨烯纳米带(GNRs)的合理合成。创造在温和条件下制造功能性多环芳烃和GNR的新方法具有重要价值。最近，我们描述了在Brnsted酸的促进下，通过炔烃的双环或四环反应来合成Py、Peropyane和Teropyene衍生物的方法。GNRs的成功合成进一步证明了该方法在快速构建大分子多环芳烃方面的应用。
Abstract The rational synthesis of atomically precise polycyclic aromatic hydrocarbons (PAHs) and graphene nanoribbons (GNRs) has been achieved by using ‘bottom-up’ strategies. The creation of new methods to make functional PAHs and GNRs under mild conditions is of significant value. Recently, we have described the synthesis of pyrene, peropyrene, and teropyrene derivatives through the double or quadruple cyclization reaction of alkynes promoted by Brønsted acids. The successful synthesis of GNRs further exemplified the application of this method to the rapid construction of large PAHs.
