A Water-Stable 3D Luminescent Metal−Organic Framework Based on Heterometallic [Eu^III₆Zn^II] Clusters Showing Highly Sensitive, Selective, and Reversible Detection of Ronidazole

Abstract

A water-stable 3D luminescent metal-organic framework (MOF), [Eu₆Zn(μ₃-OH)₈(NDC)₆(H₂O)₆]_n (1), constructed from heterometallic [Eu^III₆Zn^II] clusters and electron-rich π-conjugated 1,4-naphthalenedicarboxylic acid (H₂NDC) ligands exhibits highly sensitive, selective, and reversible detection of ronidazole, which represents the first example of luminescent MOFs based on Ln-TM heterometallic clusters for the detection of antibiotics in aqueous solution.
