Synthesis and Characterization of Triple-decker Sandwich Dinuclear La(III) and Lu(III) Complexes of 2,3,9,10,16,17,23,24-Octabutoxyphthalocyanine

The title complexes, [La2(obPc)3] (1) and [Lu2(obPc)3] (2) (H2obPc = 2,3,9,10,16,17,23,24-octabutoxyphthalocyanine), were obtained in a pure form and in good yields and characterized by means of mass, 1H NMR, and UV-visible (vis) spectroscopy and cyclic voltammetry.
