Synthesis and study of properties of the sulfonaphthylazophenoxyphthalonitrile and related phthalocyanine
2011
The 4-[4′-(5-sulfonaphthylazo)phenoxy]phthalonitrile potassium salt was synthesized by the reaction of 4-chlorophthalonitrile with 5-(4′-hydroxyphenylazo)-1-naphthalenesulfonic acid, and on its basis was obtained tetra-4-[4′-(5-sulfonaphthylazo)phenoxy]phthalocyanine. The products were characterized by elemental analysis, IR and electron spectroscopy. The effect of the introduced substituent on the spectral and other properties of the synthesized compounds was demonstrated.
