Synthesizing graphdiyne with a well-defined structure is a great challenge. We reported herein a rational approach to synthesize graphdiyne nanowalls using a modified Glaser-Hay coupling reaction. Hexaethynylbenzene and copper plate were selected as monomer and substrate, respectively. By adjusting the ratio of added organic alkali along with the amount of monomer, the proper amount of copper ions was dissolved into the solution, thus forming catalytic reaction sites. With a rapid reaction rate of Glaser-Hay coupling, graphdiyne grew vertically at these sites first, and then with more copper ions dissolved, uniform graphdiyne nanowalls formed on the surface of copper substrate. Raman spectra, UV-vis spectra, and HRTEM results confirmed the features of graphdiyne. These graphdiyne nanowalls also exhibited excellent and stable field-emission properties.

使用乙炔偶联反应合成石墨炔纳米壁

合成具有明确结构的石墨炔是一项巨大的挑战。我们在此报告了一种使用改进的 Glaser-Hay 偶联反应合成石墨炔纳米壁的合理方法。分别选择六乙炔苯和铜板作为单体和基材。通过调节加入有机碱的比例和单体用量，使适量的铜离子溶解在溶液中，形成催化反应位点。由于 Glaser-Hay 偶联反应速度快，石墨炔首先在这些位点垂直生长，然后随着更多的铜离子溶解，在铜基板表面形成均匀的石墨炔纳米壁。拉曼光谱、紫外-可见光谱和 HRTEM 结果证实了石墨炔的特征。
