An alkali-resistant Zn-MOF directed by [BMI]Br ionic liquid, (BMI)[Zn(ptptc)] (1), based on a π-electron-rich terphenyl-tetracarboxylic acid, has been synthesized under the combination of hydro/solvothermal and ionothermal condition (BMI = 1-butyl-3-methylimidazolium, Hptptc = -terphenyl-3,3'',5,5''-tetracarboxylic acid). In 1, the trinuclear Zn(ii) clusters are linked by the organic moieties of the ptptc ligands, resulting in a 3D anionic framework structure with highly disordered [BMI] cations filled in the pores. 1 exhibits good chemical stability in water and NaOH solutions (pH range of 7-12), which allow it to detect antibiotics and nitroaromatic explosives in an aquatic system. 1 represents high fluorescence quenching efficiency toward NFs (furazolidone, FZD; nitrofurazone, NZF; nitrofurantoin, NFT), NMs (ronidazole, RDZ; metronidazole, MDZ; dimetridazole, DTZ; ornidazole, ODZ) and nitrophenol (2-nitrophenol, 2-NP; 3-nitrophenol, 3-NP; 4-nitrophenol, 4-NP; 2,4,6-trinitrophenol, TNP) in water solution, respectively.
由[BMI]Br离子液体导向的一种耐碱锌基金属有机框架化合物（BMI）[Zn(ptptc)]（1），基于富π电子的三联苯四羧酸，在水热/溶剂热和离子热条件相结合的情况下合成（BMI = 1-丁基-3-甲基咪唑鎓，Hptptc = 三联苯-3,3'',5,5''-四羧酸）。在化合物1中，三核Zn(ii)簇通过ptptc配体的有机部分相连，形成一种三维阴离子框架结构，孔隙中填充有高度无序的[BMI]阳离子。化合物1在水和NaOH溶液（pH范围为7 - 12）中表现出良好的化学稳定性，这使其能够在水生系统中检测抗生素和硝基芳香族炸药。化合物1对水溶液中的硝基呋喃类药物（呋喃唑酮，FZD；呋喃西林，NZF；呋喃妥因，NFT）、硝基咪唑类药物（甲硝唑，RDZ；甲硝唑，MDZ；二甲硝唑，DTZ；奥硝唑，ODZ）和硝基苯酚（2-硝基苯酚，2-NP；3-硝基苯酚，3-NP；4-硝基苯酚，4-NP；2,4,6-三硝基苯酚，TNP）分别表现出高荧光猝灭效率。
