Metal-Assisted and Solvent-Mediated Synthesis of Two-Dimensional Triazine Structures on Gram Scale 2020 Access copy available to the general public Unrestricted Covalent triazine frameworks are an emerging material class that have shown promising performance for a range of applications. In this work, we report on a metal-assisted and solvent-mediated reaction between calcium carbide and cyanuric chloride, as cheap and commercially available precursors, to synthesize two-dimensional triazine structures (2DTSs). The reaction between the solvent, dimethylformamide, and cyanuric chloride was promoted by calcium carbide and resulted in dimethylamino-s-triazine intermediates, which in turn undergo nucleophilic substitutions. This reaction was directed into two dimensions by calcium ions derived from calcium carbide and induced the formation of 2DTSs. The role of calcium ions to direct the two-dimensionality of the final structure was simulated using DFT and further proven by synthesizing molecular intermediates. The water content of the reaction medium was found to be a crucial factor that affected the structure of the products dramatically. While 2DTSs were obtained under anhydrous conditions, a mixture of graphitic material/2DTSs or only graphitic material (GM) was obtained in aqueous solutions. Due to the straightforward and gram-scale synthesis of 2DTSs, as well as their photothermal and photodynamic properties, they are promising materials for a wide range of future applications, including bacteria and virus incapacitation. info:eu-repo/grantAgreement/EC/H2020/785219/EU/Graphene Flagship Core Project 2/GrapheneCore2 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 785219-GrapheneCore2 info:eu-repo/grantAgreement/EC/H2020/823717/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM3 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823717-ESTEEM3 info:eu-repo/grantAgreement/EC/H2020/881603/EU/Graphene Flagship Core Project 3/GrapheneCore3 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 881603-GrapheneCore3 info:eu-repo/grantAgreement/ES/MICINN/GATES-PCI2018-093137 info:eu-repo/grantAgreement/ES/MINECO-AEI-FEDER/MAT2016-79776-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 15.419 2020 CHEMISTRY, MULTIDISCIPLINARY 15 / 178 = 0.084 2020 Q1 T1 7.115 2020 Biochemistry 2020 Q1 Colloid and Surface Chemistry 2020 Q1 Chemistry (miscellaneous) 2020 Q1 Catalysis 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Gholami, M.F.
