The analysis of the crystalline phases depicts a successive transformation of the precursor into different substances previously used as starting reactants, whereby melamine cyanurate arises as the ultimate precursor of a class of thermal condensation routes to obtain graphitic carbon nitride. The study of the optical properties of the synthesized materials evidences the simultaneous production of an amorphous phase with a significant presence of melon oligomers. These results are also supported by the further characterization of the materials performed using THz-TDS, FTIR, HRTEM, and XPS techniques, and by theoretical studies conducted using semi-empirical quantum chemistry methods. info:eu-repo/grantAgreement/ES/MICINN/PID2020-119418GB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.3 2022 CHEMISTRY, INORGANIC & NUCLEAR 13 / 42 = 0.31 2022 Q2 T1 CHEMISTRY, PHYSICAL 88 / 161 = 0.547 2022 Q3 T2 0.58 2022 Ceramics and Composites 2022 Q2 Condensed Matter Physics 2022 Q2 Physical and Theoretical Chemistry 2022 Q2 Inorganic Chemistry 2022 Q2 Materials Chemistry 2022 Q2 Electronic, Optical and Magnetic Materials 2022 Q2 5.6 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Dante, Roberto C.
