| description | Owing to their enriched host-guest chemistry and high porosity, metal-organic frameworks (MOFs) applied extensively in the detection of a large variety of hazardous chemicals, especially metal ions, using different instrumental methods, such as photoluminescence. In this study, two pillar-layered MOFs, [Cu2(BDC)2(DABCO)] and its amine-functionalized isostructure, [Cu2(NH2-BDC)2(DABCO)], were successfully prepared to highlight the amino group role in the metal ions sensing via exploiting photoluminescence-based method. These materials could recognize copper(II) cations efficiently by changing the luminescent response in less than 20 minutes. With increasing the concentration of Cu(II) solution, first, the luminescent response changes occurred intensely, then equilibrium was reached and no more changes were observed. In the presence of other metal cations, the sensors almost recognized the analyte selectively. At the end of the experimental tests, the reasonable mechanism of sensing was proposed using FTIR spectroscopy and PXRD patterns. They confirmed that the introduction of analyte does not collapse the structure, so just the chemical interaction between the walls of pores and Cu(II) ions are responsible for the purposed application. |
