新型sp-hybridized碳同素异形体的合成是一个有意义且具有挑战性的问题。在炔基碳家族中，多环芳烃炔是一个有待开发的新的分支。本文以电石和四氯萘为原料，通过定向力化学反应，合成了具有炔基连接萘基骨架结构的萘。其独特的性质和结构与广泛的炔基萘基共轭，多层纳米膜形态，和高的结构稳定性得到了证实的综合表征结合计算机模拟。由于这些结构特征，所制备的萘可用作高性能无粘合剂的超级电容器电极，其具有高比电容（154 F g（-1））、稳健的长期保持率（5000次循环后92.1%）和突出的电导率（1490 S m（-1））。萘炔的成功构型为合成多环芳烃炔提供了可行性，并为炔基碳材料的开发提供了一条有前景的途径。
The synthesis of new sp-hybridized carbon allotropes is a meaningful and challenging issue. Among the alkynyl carbon family, polyaromatic alkynes is a new branch to be developed. Herein, naphyne with a frame construction of alkynyl-linked naphthyl skeleton was efficiently fabricated through targeted mechanochemical reaction of calcium carbide and perchloronaphthalene. Its unique property and structure with wide alkynylnaphthyl conjugation, multilayered nanofilm morphology, and high structural stability were corroborated by the comprehensive characterizations combined with computational simulations. Because of these structural features, the as-prepared naphyne can be applied as high-performance binder-free supercapacitor electrode with high specific capacitance (154 F g(-1)), robust long-term retention (92.1% after 5000 cycles), and prominent electrical conductivity (1490 S m(-1)). The successful architecture of naphyne approves the feasible synthesis of polyaromatic alkynes and further may provide a prospective approach for the development of alkynyl carbon materials.
