二维（2D）层状石墨氮化碳（gCN）纳米片提供了有趣的电子和化学性质。然而，用于特定应用的gCN的剥离和官能化仍然具有挑战性。我们报告了一种可扩展的一锅还原方法，以从聚三嗪酰亚胺以高质量产率（35%）生产具有优异稳定性的单层和少层2D gCN纳米片的溶液。高分辨率成像证实了完整的晶体结构，并确定了gCN层的AB堆叠。电荷允许溶解的gCN的有意有机官能化，提供了调节其性质的一般途径。
Two‐dimensional (2D) layered graphitic carbon nitride (gCN) nanosheets offer intriguing electronic and chemical properties. However, the exfoliation and functionalisation of gCN for specific applications remain challenging. We report a scalable one‐pot reductive method to produce solutions of single‐ and few‐layer 2D gCN nanosheets with excellent stability in a high mass yield (35 %) from polytriazine imide. High‐resolution imaging confirmed the intact crystalline structure and identified an AB stacking for gCN layers. The charge allows deliberate organic functionalisation of dissolved gCN, providing a general route to adjust their properties.
