Abstract

Abstract : One 14-metal Nd(iii ) nanoring was constructed using a rigid tridentate ligand, and it shows NIR luminescent response to NFAs with high sensitivity even in the presence of other antibiotics. Abstract : One NIR luminescent 14-metal Nd(iii ) nanoring (1, molecular size: 1.0 × 2.2 × 2.6 nm) was obtained from a rigid tridentate ligand, which can absorb and transfer light energy to the Nd(iii ) ions. 1 shows interesting luminescence sensing activity to antibiotics, in particular to NFAs with high sensitivity due to the inner filter effect. The quenching constants and the limits of detection of 1 to NFAs are 1.05 × 10 4 M −1 –2.33 × 10 4 M −1 and 3.05 μM–6.75 μM, respectively. The high fluorescence sensitivities of 1 to NFAs are not changed by the existence of other antibiotics. It also exhibits high sensitivity in the luminescent detection of NFAs contained in real antibiotic drugs.
