石墨二炔（GDY）是石墨炔（戈伊）家族中一种新兴的碳同素异形体，在电子器件、催化、电化学储能、非线性光学等领域具有广泛的应用前景。少层GDY的合成对于电子应用和结构表征都特别重要。这项工作批判性地总结了GDY的最新技术水平，并专注于探索几层GDY合成的方法。详细分析了GDY合成的障碍和挑战。讨论了最近开发的合成方法，例如i）基于铜基底的方法，ii）化学气相沉积（CVD）方法，iii）界面构建方法，以及iv）石墨烯模板化方法。在整个讨论过程中，综合分析了各种方法的优势和局限性。这些合成方法为进一步研究多层或单层GDY膜的合成提供了很大的启示。最后，展望了具有更高结晶质量的层控和形貌控制合成GDY的有前途的研究方向和剩余障碍。
Graphdiyne (GDY) is an emerging carbon allotrope in the graphyne (GY) family, demonstrating extensive potential applications in the fields of electronic devices, catalysis, electrochemical energy storage, and nonlinear optics. Synthesis of few‐layered GDY is especially important for both electronic applications and structural characterization. This work critically summarizes the state‐of‐art of GDY and focuses on exploring approaches for few‐layered GDY synthesis. The obstacles and challenges of GDY synthesis are also analyzed in detail. Recently developed synthetic methods are discussed such as i) the copper substrate‐based method, ii) the chemical vapor deposition (CVD) method, iii) the interfacial construction method, and iv) the graphene‐templated method. Throughout the discussion, the superiorities and limitations of different methods are analyzed comprehensively. These synthetic methods have provided considerable inspiration approaching synthesis of few‐layered or single‐layered GDY film. The work concludes with a perspective on promising research directions and remaining barriers for layer‐controlled and morphology‐controlled synthesis of GDY with higher crystalline quality.
