It is important to develop sensors that can be easily fabricated for the detection of harmful industrial wastes and nitroaromatic explosives to reduce the risks to human health and protect the environment. We report a new luminescent metal–organic framework (MOF), [Zn5(μ3-OH)2(TDA)4(4,4′-bpt)2]n (1), (4,4′-bpt = 1H-3,5-bis-(4-pyridyl)-1,2,4-triazole, H2TDA = thiophene-2,5-dicarboxylic acid), which was synthesized under solvothermal conditions and characterized using the PXRD, IR, TG, ICP-MS, mapping, and PL spectroscopic techniques. The {Zn5} MOF of (1) with Zn5 cluster as the node, and 4,4′-bpt and TDA2− as linkers, exhibited excellent thermal and chemical stabilities. Furthermore, 1 can serve as a sensitive and recyclable luminescent probe for the detection of Ag+, Cr2O72−, and TNP with detection limits of 5.96, 4.34, and 1.59 μM, respectively.

基于 {Zn5} 簇的金属有机框架：Ag+、Cr2O72- 和 2,4,6-三硝基苯酚 (TNP) 的多功能检测
开发易于制造的传感器以检测有害工业废物和硝基芳香族爆炸物以降低对人类健康的风险并保护环境非常重要。我们报道了一种新的发光金属-有机骨架（MOF），[Zn 5 (μ 3 -OH) 2 (TDA) 4 (4,4′-bpt) 2 ]n ( 1 ), (4,4′-bpt = 1 H -3,5-bis-(4-pyridyl)-1,2,4-triazole, H 2 TDA = thiophene-2,5-dicarboxy acid)，在溶剂热条件下合成并使用 PXRD、IR 表征、TG、ICP-MS、映射和 PL 光谱技术。( 1 )的{Zn 5 } MOF与Zn 5簇作为节点，4,4'-bpt 和 TDA 2-作为接头，表现出优异的热稳定性和化学稳定性。此外，1可用作检测 Ag +、Cr 2 O 7 2-和 TNP 的灵敏且可回收的发光探针，检测限分别为 5.96、4.34 和 1.59 μM。
