Microwave-Assisted Synthesis, Characterization and Spectral Properties of Non-Peripherally Tetra-Substituted Phthalocyanines Containing Eugenol Moieties

Abstract

The microwave-assisted synthesis and characterization of novel non-peripherally eugenol substituted metallophthalocyanines (M: Co(II), Ni(II), Cu(II), Zn(II)) have been reported for the first time in this study. All the new compounds were characterized by a combination of FT-IR, 1H NMR, 13C NMR, and UV/vis spectroscopy techniques. The crystal structure of compound (1) was also determined by the single crystal diffraction technique. Newly synthesized eugenol substituted phthalocyanines have more redshift Q bands (about 17-18 nm) than previously reported eugenol substituted phthalocyanines. Zinc(II)phthalocyanine (1d) has an extra absorption band at 746 nm that calling "X band" at UV/vis spectrum. © 2015 Elsevier B.V. All rights reserved.
