Chemiluminescence of Tris(2,2'-bipyridyl)ruthenium(II): A glowing experience

Chemiluminescence involves the production of light by species that can undergo highly energetic electron transfer reactions. When Mg powder or turnings are added to a CH3CN-H2O (50:50 v/v) solution mixture containing 1 mM Ru(bpy)3 2+ and 40 mM S2O8 2- (CH3CN = acetonitrile, bpy = 2,2'-bipyridin...

Summary:Chemiluminescence involves the production of light by species that can undergo highly energetic electron transfer reactions. When Mg powder or turnings are added to a CH3CN-H2O (50:50 v/v) solution mixture containing 1 mM Ru(bpy)3 2+ and 40 mM S2O8 2- (CH3CN = acetonitrile, bpy = 2,2'-bipyridine, S2O8 2- = peroxydisulfate) at pH 1.2, a bright orange emission results that is easily visible in a darkened room.
