Hydroquinone (HQ) and copper ions (Cu2+) are categorized as environmental pollutants that severely limited in water. Designing a selective assay for discriminating HQ from its two isomers the convenient determination of Cu2+ is great importance. Herein, Tb-based metal-organic framework (Tb-MOF) assembled innovatively into ratiometric fluorescence nanoprobe to selectively distinguish subsequent quantitative visual detection Cu2+. The native blue emission at 338 nm used response signal, while Tb-MOF with green offers reference signal 545 nm. Notably, neither resorcinol (RC) nor catechol (CC) exhibits obvious under same experimental conditions, which enables isomers. Thus, method has been designed intensity ratio F338/F545 readout. redox reaction between induces quenching no change Tb-MOF, resulting noticeable color variation blue-green via naked eye. Furthermore, sensitive achieved low limit 1.67 μM using smartphone. satisfactory recoveries good repeatability visualization determined spiked water samples make this sensing platform suitable on-site monitoring samples.
