An excellent water-stable 3D Zn-MOF with 8-fold interpenetrated diamondoid topology showing "turn-on/turn-off" luminescent detection of Al³⁺ and SNT in aqueous media.

ABSTRACT: The effective detection of Al³⁺ and antibiotics pollutants is crucial for environmental protection and human health due to their high toxicity and nondegradability, but it is still currently challenging. In this work, a methyl-decorated acylamide-containing dicarboxylate ligand H₂L was elaborately designed and successfully synthesized, which was further employed to react with Zn(ii) ions and dpe ligands to construct a new luminescent Zn-MOF, namely {[Zn(L)(dpe)]·DMF·3H₂O} _n (1). X-ray crystallography reveals that MOF 1 is a 3D 8-fold [4 + 4] interpenetrated diamondoid framework with isolated DMF and water molecules in the pores, in which the uncoordinated acylamide groups are found and facilitate the Zn-MOF to recognize analyte molecules.
