Synthesis and aggregation properties of 2,9,16,23–tetrakis(chloro)-3,10,17,24–tetrakis[2-(4-allyl-2methoxyphenoxy)ethoxy]phthalocyaninato cobalt(II), manganese(III), zinc(II)

Abstract

The synthesis of original, symmetrical cobalt, manganese and zinc phthalocyanines including eight 2-(4-allyl-2-methoxyphenoxy)ethanol moieties were realized by cyclotetramerization of 4,5-bis(2-(4-allyl-2-methoxyphenoxy)ethoxy)phthalonitrile with suitable metal salts. Novel compounds having eugenol moieties were characterized by spectroscopic techniques such as FT-IR, UV-vis, 1H NMR, 13C NMR and mass spectra. Within the scope of this study, solutions peripheral octa-substituted cobalt (II), manganese (III) and zinc (II) phthalocyanine compounds were prepared in different solvents and concentrations. Then, UV-vis spectra were examined to investigate the effect of solvent and concentration on aggregation.
