Preparation and preliminary evaluation of anhydrous tris(2,2′-bipyridyl)ruthenium(III) perchlorate as a temporally stable reagent for analytical chemiluminescence

A new method for producing solutions of tris(2,2′-bipyridyl)ruthenium(III) ([Ru(bipy) 3] 3+) which have significantly improved stability over other methods is presented and preliminary analytical evaluation of the reagent for chemiluminescence is reported. The synthesis of anhydrous tris(2,2′-bipyri...

Description
Summary:A new method for producing solutions of tris(2,2′-bipyridyl)ruthenium(III) ([Ru(bipy) 3] 3+) which have significantly improved stability over other methods is presented and preliminary analytical evaluation of the reagent for chemiluminescence is reported. The synthesis of anhydrous tris(2,2′-bipyridyl)ruthenium(III) perchlorate ([Ru(bipy) 3](ClO 4) 3) salt is described and the use of acetonitrile as solvent to minimise the presence of water which can be oxidised by [Ru(bipy) 3] 3+, which causes the inherent instability. The stability of the new reagent in acetonitrile was monitored spectrophotometrically ( λ max∼674 nm) and a decrease of
