Microwave-assisted synthesis and characterization of differently substituted phthalocyanines containing 3,5-dimethoxyphenol and octanethiol moieties

Abstract

New differently substituted metal-free and metal (Cu, Zn) phthalocyanines are described. One group (1, 2, 3) contains peripheral 3,5-dimethoxyphenoxy and chloro substituents and the other group (4, 5, 6) contains 3,5-dimethoxyphenoxy and octanethiol substituents. All products were synthesized by both classical and microwave-assisted methods. Structures were confirmed by elemental analysis, H-1 NMR, C-13 NMR, UV/vis and FTIR spectroscopies. The crystal structure of starting material I was also determined using a single crystal diffraction technique. All of the complexes were only slightly soluble in polar solvents such as CHCl3, DMF and DMSO. (C) 2006 Elsevier Ltd. All rights reserved.
