Abstract
Abstract
In this work, a novel metal-organic framework (MOF) based on 2,6-di(1H-imidazol-1-yl)naphthalene (L) and biphenyl-3,4′,5-tricarboxylic acid (H3bptc), namely [Co(L)(Hbptc)(H2O)] (1), has been prepared. 1 has a distinct infinite chain structure, further linked together by winding interactions to give the three-dimensional (3D) network structure. 1 was characterized by X-ray crystallography, infrared spectra (IR) spectroscopy, elemental and thermal analysis. Photoluminescence studies revealed that 1 shows a strong emission at 361 nm upon excitation at 290 nm at room temperature. Moreover, 1 can efficiently detect Fe3+ ions by luminescence quenching.
