摘要:
Six isomorphous metal-organic frameworks: M-2(ATPA)(3)(DMF)(2)(H2O)(2) (M = Nd (1), Sm (2), Eu (3), Gd (4). Tb (5), Dy (6); ATPA = 2-aminoterephthalate, DMF = N,N-dimethylformamide), were synthesized by the self-assembly of lanthanide ions, 2-aminoterephthalate, DMF and H2O. Their crystal structures determined by X-ray crystallography reveal interpenetrating frameworks. Compounds 2, 3, 5 and, 6 exhibit mainly ligand luminescence at room temperature while 3 exhibits enhanced Eu3+ emissions at 77 K. Magnetic studies indicate 4 is paramagnetic with slight Gd3+-Gd3+ couplings. (C) 2009 Elsevier B.V. All rights reserved.
