Selective Synthesis of Binuclear and Trinuclear Phthalocyanines Covalently Linked by a One Atom Oxygen Bridge

Article abstract of DOI:10.1055/s-1986-31654

The diiminoisoindolines obtained from 4-neopentoxyphthalonitrile and bis<3,4-dicyanophenyl> ether gave, in a mixed condensation reaction, binuclear and trinuclear phthalocyanines covalently linked by one atom oxy bridges with the dimer predominating.The underivatized 4-neopentoxyphthalonitrile condensed with the diiminoisoindoline of bis<3,4-dicyanophenyl> ether in a cross reaction to give the same dimer and trimeric phthalocyanines but the trimer predominated in this reaction.A cobalt derivative of bis-2-<9,16,23-trineopentoxyphthalocyaninyl> ether, the binuclearphthalocyanine, was prepared.All phthalocyanines exhibited parent ions in their fast atom bombardment mass spectra.
