Phthalocyanines obtained from phthalonitriles with phenyl derivatives: A new method for the synthesis of the phthalonitriles by use of Suzuki-Coupling reaction

Phthalocyanines peripherally introduced with four phenyl derivatives have been prepared from the corresponding phthalonitriles, which were obtained in high yields with Suzuki-Miyaura coupling. It was found that the substituent groups on the pc ring significantly affect the spectral properties and solubilities in chloroform.
