通过组装工艺成功合成了具有优异稳定性的tbiii -有机骨架[TbL·2H2O]n（配合物1）。由于配合物1具有优异的水稳定性和较强的绿色发光特性，研究人员考虑将其作为Fe3+、Cr2O72-和呋喃妥英（NFT）水溶液的可逆多响应发光传感器。配合物1不仅具有高选择性、高灵敏度的检测效果，而且具有显著的循环再生能力。水体中Fe3+、Cr2O72-和NFT络合物1的Ksv值分别为2.27 × 104、2.31 × 104和5.26 × 104 M-1。更重要的是，配合物1可以通过发光猝灭检测准确监测真实牛血清样品中的NFT。
An excellently stable TbIII-organic framework, [TbL·2H2O]n (complex 1), has been successfully synthesized through an assembly process. By virtue of its excellent water stability and strong green luminescence, complex 1 has been considered and applied as a reversible multi-responsive luminescent sensor for Fe3+, Cr2O72-, and nitrofurantoin (NFT) aqueous solutions. Complex 1 not only exhibits outstanding detection effects with high selectivity and sensitivity, but also shows remarkable cycling and regeneration abilities. The Ksv values of complex 1 for Fe3+, Cr2O72-, and NFT are 2.27 × 104, 2.31 × 104, and 5.26 × 104 M-1 in water systems, respectively. More importantly, complex 1 can accurately monitor NFT in real bovine serum samples via luminescence quenching detection.
