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.
