β-Graphdiyne (β-GDY) is a two-dimensional carbon material with zero band gap and highly intrinsic carrier mobility and a promising material with potential applications in electronic devices. However, the synthesis of continuous single or ultrathin β-GDY has not been realized yet. Here, we proposed an approach for ultrathin β-GDY-like film synthesis using graphene as a template because of the strong π–π interaction between β-GDY and graphene. The as-synthesized film presents smooth and continuous morphology and has good crystallinity. Electrical measurement reveals that the film presented a conductivity of 1.30 × 10^–2 S·m^–1 by fabricating electronic devices on β-GDY grown on a dielectric hexagonal boron nitride template.

Eglinton偶联反应合成超薄β-石墨二炔样薄膜的模板

β-Graphdiyne（β-GDY）是具有零带隙和高固有载流子迁移率的二维碳材料，是一种有前途的材料，具有在电子设备中的潜在应用。但是，尚未实现连续的单或超薄β-GDY的合成。在这里，我们提出了一种以石墨烯为模板的类似β-GDY的超薄薄膜合成方法，因为β-GDY和石墨烯之间存在很强的π-π相互作用。合成后的薄膜呈现出平滑连续的形态，并具有良好的结晶度。电学测量表明，通过在电介质六方氮化硼模板上生长的β-GDY上制造电子器件，该膜的电导率为1.30×10 ^-2 S·m ^–1。
