Aqueous-phase detection of antibiotics and nitroaromatic explosives by an alkali-resistant Zn-MOF directed by an ionic liquid.

ABSTRACT: An alkali-resistant Zn-MOF directed by [BMI]Br ionic liquid, (BMI)₂[Zn₃(ptptc)₂] (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, H₄ptptc = p-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 quenchin
