Abstract

By using a new N-donor ligand, a 3D stable pillared-layer metal–organic framework, namely [Cu4(1,4-ndc)4(L)2]·H2O·2DMF (1), has been synthesized under solvothermal conditions (1,4-H2ndc = 1,4-naphthalenedicarboxylate; L = 1-(1-(1H-imidazol-1-yl)naphthalen-4-yl)-1H-imidazole). X-ray single crystal diffraction analysis was utilized to obtain the crystal structure of 1 and 1 was further characterized by elemental analysis, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and infrared spectroscopy (IR). Based on dinuclear Cu(II) clusters as nodes, compound 1 is a 6-connected two-fold interpenetrating pcu network. Moreover, using rhodamine B (RB) and methylene blue (MB) as examples, 1 has the ability to separate dye molecules. Finally, the magnetic properties of 1 have been investigated.
