Three water-stable luminescent MOFs [Zn(bptc)(NMP)(DMF)(HO)] (1-a), [Cd(bptc)(NMP)(DMF)(HO)] (1-b), and {[Zn(bptc)(DMA)(HO)]·(DMA)·HO} (2), possessing similar chemical components (M:L:Sol) and topology structures, were synthesized by solvents control. Their excellent sensing on iron(III) cation and nitroaromatic explosives (NACs) with great selectivity, sensitivity and a high K (4.54 × 10 for 1-b on PNP) were observed by quenching effects. Furthermore, Zn-MOFs exhibit interesting stimuli-responsive luminescence enhancement after the encapsulation of a series of IIIB cations stimulated different luminescent emitting and intensity enhancement through host-guest processes of the pores in MOFs, especially for two distinct responses of Zn-MOF on a Tb cation.
通过溶剂控制合成了三种水稳定的发光金属有机框架材料[Zn(bptc)(NMP)(DMF)(HO)] (1-a)、[Cd(bptc)(NMP)(DMF)(HO)] (1-b)和{[Zn(bptc)(DMA)(HO)]·(DMA)·HO} (2)，它们具有相似的化学成分（M:L:Sol）和拓扑结构。通过猝灭效应观察到它们对铁（III）阳离子和硝基芳香族炸药（NACs）具有出色的传感性能，具有很高的选择性、灵敏度和高K值（1-b对PNP的K值为4.54×10）。此外，锌基金属有机框架材料在封装一系列IIIB族阳离子后表现出有趣的刺激响应发光增强现象，通过金属有机框架材料孔道的主客体过程激发了不同的发光发射和强度增强，特别是锌基金属有机框架材料对铽阳离子有两种不同的响应。
