Abstract：

The　establishment　of　an　ordered　structure　can　significantly　improve　the　physical　and　chemical　properties　of　polymer-based　devices.　Melon-based　carbon　nitride,　an　advanced　conjugated　material,　faces　considerable　challenges　in　achieving　long-range　order　structures,　largely　due　to　the　uncontrollable　synthesis　kinetics　of　random　deamination　sites　and　disordered　elementary　structural　assemblies.　In　this　study,　we　addressed　these　challenges　and　achieved　controllable　the　synthesis　of　long-range　ordered　carbon　nitride　via　ammonia　assisted　polymerization.　The　ordered　structure　greatly　facilitated　the　interfacial　charge　transfer　and　separation,　leading　to　enhanced　photocatalytic　performance.　The　optimized　catalyst　demonstrated　superior　activity　and　stability　in　photocatalytic　methanethiol　oxidation,　H2O2　synthesis,　and　overall　water　splitting,　prominently　outperforming　most　reported　disordered　carbon　nitrides.　This　work　provides　new　insights　into　the　synthesis　of　ordered　melon-based　carbon　nitride　and　highlights　its　potential　for　applications　in　solar　energy　conversion.　©　2025　Elsevier　B.V.
