Abstract

The effects of metal ions on the electrochemiluminescence (ECL) properties of (bpy)₂Ru(AZA-bpy) (bpy = 2,2′-bipyridine; AZA-bpy = 4-(N-aza-18-crown-6-methyl-2,2′-bipyridine) have been investigated. The electrochemistry, photophysics and ECL of Ru(bpy)₃²⁺ in the presence of Pb²⁺, Hg²⁺, Cu²⁺, and K⁺ are reported. The anodic oxidation of Ru(bpy)₃²⁺ produces ECL in the presence of tri-n-propylamine (TPrA) in 50:50 (v/v) CH₃CN:H₂O solution. Increases in ECL efficiency (photons generated per redox event) up to 20-fold that depend on both the concentration and nature of the metal ion have been observed, making this an interesting system for electrochemiluminescence metal ion sensing.
