- Abstract
A series of five l-di- p-toluoyl-tartaric acid ( l-DTTA) lanthanide coordination polymers, namely {[Ln4K4 L6(H2O)x]⋅yH2O}n, [Ln=Dy ( 1), x=24, y=12; Ln=Ho ( 2), x=23, y=12; Ln=Er ( 3), x=24, y=12; Ln=Yb ( 4), x=24, y=11; Ln=Lu ( 5), x=24, y=12] have been isolated by simple reactions of H2L (H2L= L-DTTA) with LnCl3⋅6 H2O at ambient temperature. X-ray crystallographic analysis reveals that complexes 1- 5 feature two-dimensional (2D) network structures in which the Ln3+ ions are bridged by carboxylate groups of ligands in two unique coordinated modes. Luminescent spectra demonstrate that complex 1 realizes single-component white-light emission, while complexes 2- 4 exhibit a characteristic near-infrared (NIR) luminescence in the solid state at room temperature.
