An excellently stable Tb-organic framework, [TbL·2HO] (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 Fe, CrO, 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 K values of complex 1 for Fe, CrO, and NFT are 2.27 × 10, 2.31 × 10, and 5.26 × 10 M in water systems, respectively. More importantly, complex 1 can accurately monitor NFT in real bovine serum samples via luminescence quenching detection.
通过组装过程成功合成了一种稳定性极佳的Tb有机框架化合物[TbL·2H₂O]（配合物1）。凭借其出色的水稳定性和强烈的绿色发光特性，配合物1被视作并应用于对铁、铬酸盐和呋喃妥因（NFT）水溶液的可逆多响应发光传感器。配合物1不仅具有高选择性和高灵敏度的出色检测效果，还展现出显著的循环和再生能力。在水体系中，配合物1对铁、铬酸盐和NFT的K值分别为2.27×10⁵、2.31×10⁵和5.26×10⁵ M。更重要的是，配合物1能够通过发光猝灭检测准确监测实际牛血清样品中的NFT。
