Microwave-assisted synthesis and characterization of a new metal-free and metallophthalocyanines

Abstract

Dinitrile monomer (3) was synthesized by nucleophilic aromatic substitution of 4-phenoxyphenol (1) with 4-nitrophthalonitrile (2). The metal-free phthalocyanine (4) was prepared by the reaction of dinitrile monomer (3) with DMAE. Ni(II), Co(II), and Zn(II) metallophthalocyanines were prepared by the reaction of 3 with chlorides of Ni(II), Co(II), and Zn(II) in DMAE. The new compounds were characterized by IR, ¹H- and ¹³C-NMR, UV-Vis, elemental analysis, and MS specral data.
