A metal–organic framework, MOF-S1, was synthesized via a solvothermal reaction between 2,4,6-tris-(4-carboxyphenoxy)-1,3,5-triazine (TCPT) and zinc nitrate hexahydrate. Single-crystal powder X-ray diffraction analyses confirmed the formation of hexagonal rod-shaped crystals with trigonal (P-31c) structure featuring two-fold interpenetrated 3D framework. comprehensive characterization—including NMR spectroscopy, thermogravimetric analysis, surface area measurements (using Langmuir, t-plot, Horváth–Kawazoe, Dubinin–Radushkevich models)—revealed an ultramicroporous material Langmuir 711 m2/g median pore width ~6.5 Å. Adsorption studies using Congo Red, Methylene Blue, Methyl Orange, Rhodamine B demonstrated rapid uptake effective removal from aqueous solutions, kinetic modeling indicating dominant chemisorption mechanism. Photocatalytic tests under UV irradiation yielded degradation efficiencies ~93% for Orange ~74% B. These findings suggest that MOF-S1 is promising candidate wastewater treatment applications UV-related processes, offering strong adsorption capacity thermal stability.
