A well-defined crystalline cyano-functionalized graphdiyne (CN-GDY) is synthesized at a liquid/liquid interface through alkyne-alkyne coupling reactions. The configurations and nanostructures of CN-GDY were well characterized by TEM, SEM, AFM, XPS, and Raman spectroscopy. HR-TEM and selected area electron diffraction (SAED) in combination with structure simulation firmly revealed a 9-fold stacking mode for CN-GDY.
通过炔-炔偶联反应在液/液界面合成了一种结构明确的结晶氰基功能化石墨二炔（CN-GDY）。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、原子力显微镜（AFM）、X射线光电子能谱（XPS）和拉曼光谱对CN-GDY的构型和纳米结构进行了充分表征。高分辨透射电子显微镜（HR-TEM）和选区电子衍射（SAED）结合结构模拟，确凿地揭示了CN-GDY的九重堆积模式。
