    We describe the synthesis of tetrasulfonated silicon phthalocyanine and its oligomer product prepared by metal salt catalyzed polycondensation. The catalytic effect of H2O-free CaCl2 in quinoline is used for the polycondensation of dihydroxy silicon phthalocyanine to the cofacially arrayed oligomer. Spectroscopic characterization and photoelectron spectroscopy data of the prepared compounds are reported. We present the first results on polypyrrole films doped with these substances.
