- Hot electron injection into aqueous electrolyte solutions
- Generation of hydrated electron
- Electrochemiluminescence of tris(2,2â²-bipyridine)ruthenium(II) chelate
- Sensitive detection of luminescent labels
Tris(2,2â²-bipyridine)ruthenium(II) chelate exhibits strong electrogenerated chemiluminescence during cathodic high-voltage pulse-polarization of pointed Pt electrode in aqueous solutions. The present method is based on a field emission or other type of tunnel emission of hot electrons into an aqueous electrolyte solution. The method allows the detection of tris(2,2â²-bipyridine)ruthenium(II) and its derivatives below nanomolar concentration levels and yields linear log-log calibration plots spanning several orders of magnitude of concentration.
