摘要
A lanthanide coordination polymers (CPs) nanostructure (1) has been synthesized via a facile template-free solvothermal strategy using DMF as solvent and 2-methyl benzoic acid (2-MeBAH) as ligands. The products are characterized by powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), elemental analyses (EA), and downward luminescence. Product 1 built from Tb3+ and 2-MeBAH has one-dimensional structure which is connected by trinuclear second building units (SBUs). Downward luminescence shows that sample 1 exhibits characteristic transitions of the Tb3+ ion at 489, 544, 583, and 621 nm, and the strongest peak is at 544 nm ascribed to the transition of D-5(4) -> F-7(5) of Tb3+.
