Synthesis and characterization of new zinc-phthalocyanine with four dodecenyl-benzoic pendant groups

Abstract EN

Substituted zinc phthalocyanine was synthesized in this study.

The reaction of 4- nitro Phthalonitrile with ZnCl2 in the presence of dimethyl amino ethanol (DMEA) afforded 4,4ʹ,4ʹʹ,4ʹʹʹ- tetranitro zinc phthalocyanine.

This was reacted with 5-amino salicylic acid to yield tetra-(5-amino salicylic acid)zinc phthalocyanine.

After that, dodecenyl succinic anhydride was added on amine group of benzoic rings afforded tetra-( (E)-5-(3-(dodec-1-enyl)-2,5-dioxopyrrolidin-1-yl)-2-hydroxybenzoic acid )zinc phthalocyanine.

The phthalocyanine was separated and washed using different solvents.

The newly synthesized compounds have been characterized by elemental analysis, FT-IR, 1H NMR and UV-Visible spectroscopy techniques.
