Preparation and properties of octa-substituted phthalocyanines peripherally substituted with phenyl derivatives

2,3,9,10,16,17,23,24-Octa-substituted phthalocyanines modified with phenyl, tolyl, tert-butylphenyl, and trifluoromethylphenyl groups and their nickel(II) complexes were prepared and characterized. The phthalonitriles with the phenyl derivatives, which are precursors of the phthalocyanines, were synthesized from 4,5-dichlorophthalonitrile and phenyl boronic acids by use of Suzuki-coupling reaction.
