Abstract

The synthesis and characterization of new metal-free (8) and metal derivatives of a symmetrically four substituted porphyrazines (7,9) derived from 15,18,23,26-tetraoxa-5,8-dithia-1,12-diazabicyclo[10.8.8]octacos-6-ene-6,7-dicarbonitrile (6), which were synthesized in a multi-step reaction sequence have been investigated. These compounds were prepared starting from dicyanoethylene containing macrobicycle which contains sulfur, oxygen as well as nitrogen heteroatoms. These pigments were characterized by H-1, (13) C NMR, IR, UV-vis, mass spectrometry, microanalysis and AA spectrophotometry. (C) 2006 Published by Elsevier Ltd.
