Electrochemical measurements on a series of [NBu4][Ln(III)Pc2] ([NBu4]=tetra(n-butyl)ammonium; Ln=Y, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Tm, Er, Yb, and Lu; Pc=phthalocyanine) are reported. The first and second oxidation potentials decrease linearly with a decrease in ionic radii of the center metals, while the reduction potentials showed no observable change. A few complexes of earlier lanthanides showed irreversible redox couples at the second oxidation potentials.
