Abstract
A novel three-dimensional (3D) anionic anhydrous metal − organic framework (MOF), {[NH2(CH3)2]·[Tb(pdca)2]}n (Tb-MOF; H2pdca = 2,5-pyridinedicarboxylic acid) has been triumphantly fabricated and structurally characterized. The obtained Tb-MOF displays good stability in some common solvent systems and high temperature environments. The luminescence properties of Tb-MOF are investigated by fluorescence spectra, and the results exhibit superb characteristic emission of Tb3+ ions, which lay a foundation for exploring the fluorescence sensing application of the material. More importantly, based on competitive absorption and dynamic quenching, Tb-MOF can be applied to detect chloroquine phosphate (CQ) used for the treatment of COVID-19 and malaria, showing high sensitivity and fast response speed in the sensing process. Notably, the specific quenchingeffect between Tb-MOF and CQ in the serum system without interference from other components, demonstrating the practical application potential of Tb-MOF.
