Electrochemical reduction of a diazonium complex [Ru-(bpy)(trpy-ph-N ₂⁺)(CO)](PF₆)₃([1](PF ₆)₃) (bpy = 2,2′-bipyridine, trpy-ph-N ₂⁺ = 4-(2, 2′:6′,2″-terpyridine- 4′-yl)benzenediazonium) using a GC electrode forms multilayer films of the complexes on the electrode surface, on which the reduced form of the complex showed strong affinity toward CO₂.
