Phenylsulfanyl(fluoro)-substituted phthalocyanine nickel complexes: Synthesis and self-association

Resumo

By cross-condensation of 4,5-bis(phenylsulfanyl)phthalonitrile (A) with tetrafluorophthalo-nitrile (B) in the presence of nickel acetate nickel phthalocyanines of the type A₄, A₃B, ABAB, AABB were synthesized. Their spectral properties were studied and the propensity to association in benzene solutions was revealed. The concentration of complexes where the association becomes notable decreases with the increased dipole moment of the phthalocyanine.
