Synthesis and Properties of 4-[(E)-(4 '-R-Phenyl)diazenyl]phthalonitriles and Cobalt Phthalocyanines Obtained Therefrom

摘要

The diazotization-azocoupling method has been utilized to prepare a series of previously unknown 4-[(E)-(4'-R-phenyl)diazenyl]phthalonitriles, which were further transformed into the corresponding cobalt phthalocyanines. The effect of the peripheral substitution of the phthalocyanine ligand on the spectral properties of the prepared compounds has been demonstrated.
