We describe the synthesis of tetrasulfonated silicon phthalocyanine and its oligomer product prepared by metal salt catalyzed polycondensation. The catalytic effect of H ~2~ O -free CaCl ~2~ in quinoline is used for the polycondensation of dihydroxy silicon phthalocyanine to the cofacially arrayed o
