Ruthenium(II) complex-based fluorescent sensor for peroxynitrite
摘要:
We have developed a new ruthenium complex, Ru(bpy)(2)[4-(2,2'-bipyridin-4-yloxy)phenol]Cl-2 (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. Rid. exhibits a good selectivity for ONOO- over other reactive oxygen species (ROS) and reactive nitrite species (RNS), and the reaction time is less than 1.5s. The sensing mechanism is proposed as the oxidative O-dealkylation reaction. (C) 2012 Elsevier B.V. All rights reserved.
