Abstract

Main observation and conclusion: One near‐infrared (NIR) luminescent octanuclear Zn(II)‐Yb(III) complex [Zn6 Yb2 L4 (OAc)2 (DMF)EtOH] (1) was obtained from a new multidentate Schiff base ligand. It exhibits interesting luminescent sensing activity to antibiotics, in particular to nitrofuran antibiotics (NFAs) with high sensitivity due to the inner filter effect. The NIR luminescence quenching constants and limits of the detection of the complex towards NFAs are 2.9 × 10 4 —5.5 × 10 4 L/mol and 1.27—2.38 μmol/L, respectively. Its high luminescence sensitivity to NFAs is not changed with the existence of other antibiotics. Abstract : One octanuclear Zn(II)‐Yb(III) complex [Zn6 Yb2 L4 (OAc)2 (DMF)EtOH] with NIR luminescent response towards antibiotics was constructed.
