One 18-metal Nd(III) nanoring, [Nd18(L1)8(HL2)2(OAc)20(MeOH)8(EtOH)6(H2O)4]·2(MeOH)·6(H2O) (1), was constructed by the use of a hexadentate Schiff base ligand. For 1, the near-infrared (NIR) luminescence of Nd(III) was detected under the excitation of absorption band at 371 nm. The study of luminescent sensing properties exhibits that, even with the existence of other antibiotics, this Nd(III) nanoring displays high sensitivity and selectivity to nitrofuran antibiotics (NFAs). The luminescence quenching constants and limits of detection of 1 to NFAs are found to be 1.4 × 104 to 3.5 × 104 M–1 and 0.9–2.2 μM, respectively.

NIR发光对抗生素的18金属钕(III)纳米环的构建

一个18金属Nd(III)纳米环,[Nd 18(L 18(HL 22(OAc)20(MeOH)8(EtOH)6(H 2 O)4 ]·2(MeOH)·6(通过使用六齿席夫碱配体构建H 2 O)(1)。对于1,在371 nm的吸收带激发下检测到Nd(III)的近红外(NIR)发光。发光感测特性的研究表明,即使存在其他抗生素,这种Nd(III)纳米环对硝基呋喃抗生素(NFA)也显示出高灵敏度和选择性。发现1至NFA的发光猝灭常数和检出限分别为1.4×10 4至3.5×10 4 M –1和0.9–2.2μM。
