Herein, we demonstrate mechanochemical approaches that enable the synthesis of C <jats:sub>2</jats:sub> N materials, namely by (i) the conversion of hexaazatriphenylenehexacarbonitrile (HAT‐CN) and by (ii) a one‐pot route starting from its molecular precursors, hexaketocyclohexane, and diaminomaleonitrile. Compared with conventional pyrolytic methods, mechanochemical approaches afford higher yields while significantly reducing energy input, thereby improving overall sustainability. The results highlight the decisive role of mechanical energy in directing carbon–nitrogen framework formation and demonstrate mechanochemistry as a versatile alternative to thermal routes for C <jats:sub>2</jats:sub> N synthesis. </jats:p> Wiley2026 eng 1864-5631 1864-564X10.1002/cssc.70678 199 @article{Dippner_Grätz_Lins_Gutmann_Borchardt_2026, title={Mechanochemical Near‐Ambient Synthesis of C                    ₂                    N Materials From HAT‐CN and its Precursors}, volume={19}, DOI={<a href="https://doi.org/10.1002/cssc.70678">10.1002/cssc.70678</a>}, number={9e70678}, journal={ChemSusChem}, publisher={Wiley}, author={Dippner, Pascal and Grätz, Sven and Lins, Jonas and Gutmann, Torsten and Borchardt, Lars}, year={2026} } Dippner P, Grätz S, Lins J, Gutmann T, Borchardt L.
