a) ¹⁹F‐NMR spectra of b1, [(bpy)Cu(C₆F₅)], and their mixtures. c(b1)=c[(bpy)Cu(C₆F₅)]=0.002 M in CH₂Cl₂ solution. b) Cyclic voltammograms of b1, [(bpy)Cu(C₆F₅)], and their mixtures in CH₂Cl₂‐CH₃CN (2:1). c(b1) was 0.0027 M when alone. In all other samples, c[(bpy)Cu(C₆F₅)] was 0.0027 M and c(b1) was adjusted according to the given ratio. Conditions: Bu₄NBF₄ (0.03 M), glassy carbon disk as working electrode, Pt wire as counter electrode, Ag|AgCl, KCl(aq) as reference electrode (calibrated with Fc⁺/Fc). The scan rate: 100 mV s⁻¹.
