| Abstract: | Based on the flexible tricarboxylate ligand, tris(2-carboxyethyl) isocyanurate(H3tci), a uranyl complex of UO2(tci)·2 H2O with two-dimensional framework, was synthesized, and the crystal structure was established by X-ray single crystal diffraction. The fluorescence properties of the complex with various transition metal ions were explored, which showed the highly sensitivity to iron ions. Further detection experiments demonstrated that the uranyl complex owns high selectivity for the recognition of Fe3+with a detection limit of 2.15 mg/L. The sensitivity of the uranyl complex is better than other iron ion detection materials. The uranyl complex can be used as a promising functional luminescence sensor for Fe3+in aqueous solution, which provides experimental basis for uranyl complexes as Fe;probes. |
