Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride

Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride ([Ru (dpp) 3]2+) is an electrochemiluminescent (ECL) probe that can be used to modify the electrode surface to detect sulfate (S2O82-) and oxalate. Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride can generate excited state species based on electrochemical reactions and release photons through irreversible redox reactions. When used as a cathode to detect persulfate, it can avoid the interference of hydrogen evolution. At the same time, the anode shows a wide linear range for oxalate. Tris (4,7-diphenyl-1,10-phenanthroline) ruthenium (II) dichloride can be used to construct a regenerable ECL sensor[1][2][3].
