- Abstract
New lanthanide-organic frameworks, [Ln2(2,6-NDS)3(IP)(H2O)4] ·H2O {Ln = Sm ( 1), Eu ( 2), Tb ( 3); 2,6-NDS = 2,6-Anaphthalenedisulfonate, IP = 1 H-imidazo[4,5- f][1,10]-phenanthroline}, were synthesized and characterized. These complexes are isostructural and have three-dimensional structures (3D) composed of a pair of entanglement double helixes. The structure is an open framework with rhombic channels filled with uncoordinated water molecules. The photoluminescence properties of the SmIII complex ( 1) and EuIII/TbIII-doped complex were explored by adjusting the excitation wavelengths. Interestingly, SmIII complex 1 generated a white-light emission, whereas the EuIII/TbIII-doped complex (Tb0.95Eu0.05) allowed the realization of white-light emission under broad UV wavelengths. An energy transfer for TbIII5D4→EuIII5D0 was observed.
