| Popis: | Herein, a highly stable luminescent heterometallic MOF, [NaEu2(TATAB)2(DMF)3]·OH (CTGU-7, H3TATAB = 4,4′,4′′-s-triazine-1,3,5-triyltri-m-aminobenzoic acid, DMF = N,N′-dimethylformamide, CTGU = China Three Gorges University), was synthesized. CTGU-7 crystallizes in a highly symmetric cubic framework with the pyrite-type topology, constructed from a novel Eu2Na trimeric cluster as a 6-connected node. Observably, this framework remains intact in a remarkably extensive environment such as in a common solvent and aqueous solutions. CTGU-7 is demonstrated to be the first known MOF for the selective detection of oridazole antibiotics. It also exhibits high selectivity and sensitivity for nitrophenol and benzyl alcohol. Thus, this material can potentially be used as a multi-responsive luminescent sensor. |
