Abstract
Uranyl MOF {H3O·[(UO2)(H3TTHA)]·2H2O} (1) with a 2D network structure was successfully constructed by flexible 1,3,5-triazine-2,4,6-triamine hexaacetic acid (H6TTHA) as ligand and UO2(CH3COO)2·2H2O as metal source. The compound 1 was basically characterized by elemental analysis, IR spectra, UV–vis spectra, PXRD pattern and thermogravimetric analysis. Based on the fluorescence characteristics of 1, the fluorescence response to nitro compounds such as p-nitrophenol (PNP), p-dinitrobenzene (pDNB) and p-nitrotoluene (PNT) were also explored at room temperature. The experimental results showed that the compound 1 had a good potential for detecting nitro compounds due to its low detection limit and high quenching constant.
