The new metallophthalocyanines (Co, Ni, Cu, and Zn) substituted with azo compound containing eugenol moiety are described. Firstly, azo compound (I) containing eugenol moiety was synthesized by treating eugenol with p-hydroxyaniline. Then phthalonitrile compound (1) was synthesized by microwave-assisted synthesis method. The purification of phthalonitrile compound (1) was carried out by column chromatographic separation. Intramolecular hydrogen bonding in the azo compound (I) prevent base-catalyzed nucleophilic aromatic substitution of OH group belongs eugenol. At the last step, metallophthalocyanines (1a, 1b, 1c, and 1d) were synthesized by the microwave irradiation. The microwave-assisted synthesis method reduces reaction times and enhances the yield of the reactions. All phthalocyanine compounds are soluble in DMF and DMSO. The structures were confirmed by elemental analysis, H-1 NMR, C-13 NMR, UV/Vis, IR and Mass spectra. (C) 2011 Elsevier B. V. All rights reserved.
