Synthesis of cobaltphthalocyanines containing anthraquinone chromophors
Anthraquinone-substituted nitriles have been synthesized by reaction of nucleophilic substitution of bromine in 4-bromo-5-nitrophthalonitrile. The obtained substances were used for the synthesis of the corresponding cobalt complexes by the nitrile method. The compounds obtained were characterized by various physicochemical methods.
