Electrochemiluminescence quenching of tris(2,2′-bipyridyl)ruthenium

Electrochemiluminescence (ECL) of tris(2,2'-bipyridyl)ruthenium [Ru(bpy)(3)(2+)] has received considerable attention over broad applications due to its remarkably high sensitivity and extremely wide dynamic range. This review presents the state of ECL quenching of Ru(bpy)(3)(2+). After a brief introduction of the ECL of Ru(bpy)(3)(2+), we discuss in detail ECL-quenching co-reactants, the ECL-quenching mechanism and applications of ECL quenching coupled with capillary electrophoresis and flow-injection analysis.
