Ruthenium (II) tris(bipyridyl) (Figure 9-17, B) undergoes an electrochemiluminescent reaction (620 nm) with tripropylamine at an electrode surface, and this chelate is now used as a label in competitive and sandwich electrochemiluminescence immunoassays. Using this label, various assays have been developed in a flow cell using magnetic beads as the solid phase. Beads are captured at the electrode surface, and an unbound label is washed out of the cell by a wash buffer. Label bound to the bead undergoes an electrochemiluminescent reaction, and the light emission is measured by an adjacent photomultiplier tube. ... 

Improved electropolymerization was also found by Forster and coworkers using ionic liquids as the electrolyte. Electropolymerization of Ru(aphen)32+ (aphen = 5-amino-1,10-phenanthroline) 11 in this medium gave thicker films with improved conductivity. The films showed electrochemiluminescence (ECL) in the presence of tripropylamine [37].
