The pyridinedicarboxylate-Tb(III) complexes, TbPDC and Tb(PDC)₃, as luminescent probes for ATP monitoring have been conveniently prepared and characterized by FT-IR, ¹H-NMR, ESI-MS, UV-Vis, excitation, and emission spectroscopy. Interestingly, these two Tb(III) complexes were quenched by ATP by a similar mechanism via π-π stacking interaction between the chelating ligand and adenine moiety. The ability of luminescent probes applied for the determination of ATP in aqueous solution has been investigated. The dynamic ranges for the quantification of ATP are within 10−90 μM and 10−100 μM with detection limits of 7.62 and 11.20 μM for TbPDC and Tb(PDC)₃, respectively. The results demonstrated that these luminescent probes would be a potential candidate assay for ATP monitoring in hygiene assessment.

用于 ATP 监测的基于吡啶二羧酸盐-Tb(III) 复合物的发光探针

吡啶二羧酸盐-Tb(III) 配合物 TbPDC 和 Tb(PDC) ₃作为用于 ATP 监测的发光探针已被方便地制备并通过 FT-IR、¹ H-NMR、ESI-MS、UV-Vis、激发和表征。发射光谱。有趣的是，这两种 Tb(III) 复合物通过螯合配体和腺嘌呤部分之间的π - π堆积相互作用以类似的机制被 ATP 淬灭。已经研究了用于测定水溶液中ATP的发光探针的能力。的动态范围为ATP的定量是内10-90  μ M和10-100  μ米，7.62和11.20检测限 μ M代表TbPDC和Tb（PDC）₃、分别。结果表明，这些发光探针将成为卫生评估中 ATP 监测的潜在候选检测方法。
