We have developed a new ruthenium complex, Ru(bpy)2[4-(2, 2′-bipyridin-4-yloxy)phenol]Cl2 (RuL), as a fluorescent sensor to detect peroxynitrite (ONOO-). The results showed that the addition of ONOO- to the aqueous solution of RuL would result in distinct fluorescence quenching at 600 nm. RuL exhibits a good selectivity for ONOO - over other reactive oxygen species (ROS) and reactive nitrite species (RNS), and the reaction time is less than 1.5 s. The sensing mechanism is proposed as the oxidative O-dealkylation reaction.
