Abstract

2D layered graphitic carbon nitride nanosheets offer tunable electronic and chemical properties. However, exfoliation and functionalisation of gCN for specific applications remains 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 confirms the intact crystalline structure and identifies an AB stacking. The first successful deliberate organic functionalisation of dissolved gCN is illustrated, providing a general route to adjust their properties.
