Electrogenerated chemiluminescence of the platinum (II) octaethylporphyrin/tri-n-propylamine system
The electrogenerated chemiluminescence (ECL) of platinum (II) octaethyl-porphyrin (PtOEP) in acetonitrile:methylene chloride (CH3CN:CH2Cl2, 50:50 v/v) and CH2Cl2 is reported. ECL was generated upon sweep to positive potentials using tri-n-propylamine (TPrA) as an oxidative–reductive coreactant. ECL efficiencies (ϕecl) of 0.18 in CH3CN:CH2Cl2 (50:50 v/v) and 3.90 in methylene chloride were obtained using Ru(bpy)3(PF6)2 (bpy = 2,2′-bipyridine) as a relative standard (ϕecl = 1). The ECL intensity peaks at a potential corresponding to oxidation of PtOEP and TPrA, and ECL emission spectra are nearly identical to photoluminescence emission spectra, indicating that emission is from the PtOEP triplet state.
