Abstract:

A new lanthanide metal-organic framework material, [Tb2(bpt)2(H2O)2]·(DMA)4.5, with Tb3+ ion as the metal center was synthesized by solvothermal method. The material was further characterized by single crystal X-ray diffraction(SXRD), powder X-ray diffraction(PXRD), elemental analysis(EA), thermogravimetric analysis(TGA), Fourier transform infrared spectroscopy(FTIR) and fluorescence spectroscopy(FS). The results of single crystal diffraction analysis show that the compound has a three-dimensional structure containing a one-dimensional straight channel with a channel window of ca. 1.23 nm×1.10 nm. Fluorescence test results demonstrate that the detection limit for Cr3+ ions is as low as 0.22 mg/L, indicating that the compound has superior selectivity. It is expected to have potential application in the field of fluorescent detection of Cr3+ ions.
