Solid-state electrochemiluminescence of tris(2,2 '-bipyridyl) ruthenium

Electrochemiluminescence (ECL) of tris(2,2'-bipyridyl) ruthenium [Ru(bpy)(3)(2+)] has received considerable attention. By immobilizing Ru(bpy)(3)(2+) on an e electrode surface, solid-state ECL provides several advantages over solution-phase ECL, such as reducing consumption of expensive reagent, simplifying experimental design and enhancing the ECL signal.This review presents the state of the art in solid-state ECL of Ru(bpy)(3)(2+)
