What is it about?

A dual-emission ratiometric fluorescent probe CuNCs@Tb@UiO-66-(COOH)2 has been synthesized by one-pot encapsulation of Tb (III) ions and glutathione-stabilized copper nanoclusters into metal-organic frameworks UiO-66-(COOH)2. It shows excellent luminescence and good fluorescence stability in water. The ratiometric probe displays high sensitivity and good selectivity to Cu2+. The probe was successfully used in real water sample.

Why is it important?

We developed a simple, one-pot process for the synthesis of a ratiometric fluorescence sensor for the detection of Cu2+. The sensor could be used in real water samples with good repeatability and recovery. This study provides a new perspective on the design of multifunctional ratiometric fluorescent sensors using the one-pot method with MOFs as support materials and provides an effective platform for the detection of heavy metal ions.


The obtained fluorescent probe showed good results in the detection of actual samples. This work can provide the basis of method for the exploration of ratiometric fluorescence and visual sensors of trace pollutants analysis in complicated samples.
