Preparation and Electrochemical Properties of the Green Ytterbium (III) and Lutetium (III) Sandwich Complexes of Octabutoxy-Substituted Phthalocyanine

The Yb(III) and Lu(III) sandwich complexes of 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine (H2obPc) were prepared and characterized. Those electrochemical properties in CH2Cl2 were studied by means of cyclic voltammetry and absorption spectra in 320–1600 nm region monitored during controlled-potential electrolysis.
