We report a simple and efficient technique for the covalent immobilisation of a tris(2,29-bipyridyl)ruthenium(II) derivative suitable for both chemiluminescence and electrochemiluminescence detection. The inherent sensitivity and selectivity demonstrated by the chemiluminescent reaction of tris(2,29-bipyridyl)ruthenium(III) 11 has led to its widespread application for the determination of reducing species, in both static and flowing systems.2 A major drawback of the technique, however is the need to constantly supply the reagent to the site of reaction, increasing both analysis costs and waste generated.
