Synthesis and characterization of novel symmetrical phthalocyanines substituted with four benzo[d] [1,3] dioxol-5-ylmethoxy groups

Metal (Zn, Cu, Co, Mg) phthalocyanines substituted with four benzo [d] [1, 3] dioxol-5-ylmethoxy unit through oxy-bridges have been synthesized from phthalonitrile derivative, 4-(benzo [d] [1,3] dioxol-5-ylmethoxy) phthalonitrile. Benzo [d] [1,3] dioxol-5-ylmethoxy substituted Pcs showed the enhanced solubility in organic solvents. The newly prepared compounds have been characterized by elemental analyses, IR, UV-Vis, H-1 NMR spectra. (c) 2006 Elsevier B.V. All rights reserved.
