Abstract

Abstract: As a hot topic of global concern, the distinguishing and detecting of antibiotic pollution is crucial owing to its adverse effect on ecosystems and human health stemming from excessive use and poor management. Herein, a water‐stable lanthanide coordination polymer sensor (Dy‐TCPB) with multiple emitting centers is prepared. The versatile Dy‐TCPB can conveniently differentiate various antibiotics, and displays a self‐calibration luminescent response to nitrofurazone (NFZ) and furazolidone (FZD). Each antibiotic exhibits notable correlation to a unique combination of the two ligand‐to‐Dy ion emission intensity ratios, enabling two‐dimensional fingerprint recognition. Furthermore, the novel self‐calibration sensor demonstrates effective recognition of NFZ and FZD with excellent sensitivity and selectivity, and detection limits as low as 0.0476 and 0.0482 μm for NFZ and FZD, respectively. The synthetic approach for the fabrication of a singular coordination polymer exhibiting multiple emissions provides a promising strategy for the development of facile and effective ratiometric sensors. Abstract : Antibiotics detection : A water‐stable coordination polymer (Dy‐TCPB) with multiple emitting centers is applied to distinguish different antibiotics and for ratiometric sensing of nitrofurazone (NFZ) and furazolidone (FZD) with high sensitivity and selectivity. The polymer also shows great recycling ability, so both the synthetic and sensing strategies present a promising approach for the development of low‐cost and effective ratiometric sensors (see scheme).
