Key Points

To develop a sensor that can detect nanomolar levels of perrhenate in water using a luminescent response.
Created a complex known as Ru3 for the detection process
Evaluated sensor performance in pure aqueous media
Assessed sensitivity and selectivity for perrhenate
Achieved a limit of detection (LOD) of 3.4 nM
Demonstrated a strong 'turn-on' luminescent response to perrhenate
Showed high selectivity in the aqueous environment

Abstract

The optimal complex, Ru3, achieves high sensitivity and selective in a “turn-on” luminescent response to ReO 4 − in pure aqueous medium, with LOD of 3.4 nM.
