Fast Exfoliation and Functionalisation of Two‐Dimensional Crystalline Carbon Nitride by Framework Charging

Two‐dimensional (2D) layered graphitic carbon nitride (gCN) nanosheets offer intriguing electronic and chemical properties.

Description
Summary: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. Ein skalierbares, reduktives Eintopf‐Verfahren erzeugt Lösungen ein‐ und mehrschichtiger zweidimensionaler Nanoschichten aus graphitischem Kohlenstoffnitrid (gCN) mit ausgezeichneter Stabilität in hoher Massenausbeute (35 %) aus Polytriazinimid. Hochauflösende Bildgebungsverfahren wurden eingesetzt, um die intakte kristalline Struktur und die AB‐Packung zu bestätigen.
