Abstract
- Abstract: Nanocrystals of [Eu2(BDC)3(H2O)2] n (1), a lanthanide-containing metal-organic framework (MOF) with a two-dimensional layer structure, were synthesized by using a surfactant-assisted hydothermal method. Nanorods with different sizes were prepared in the presence of a cationic surfactant, cetyltrimethyl ammonium bromide, depending on various reaction times. To demonstrate the ability of 1 nanorods for detection of nitroaromatic explosives, the fluorescence quenching and fluorescence titration experiments were carried out. Fluorescence of 1 nanorods was found to be highly sensitive to the nitroaromatics such as 2-nitrotoluene, 4-nitrotoluene, 2,4-dinitrotoluene, and 2,6-dinitrotoluene, suggesting that lanthanide-containing MOF nanocrystals can be excellent candidates for the rapid detection of nitroaromatic explosives.
