Abstract

The aromatisation of 7-diethylamino-3,4-dihydrocoumarin provides an alternative fluorescent probing technique to selectively detect the concentration of superoxide anion in solution. In addition, we reported the advantage of evaluating O2˙− sensing probes in anhydrous DMSO instead of in aqueous buffers when using KO2 as the surrogate of O2˙−.
