New Octasubstituted Phthalocyanines Combining 2,4,5-Trichlorophenol and Nitro Groups at the Periphery: Synthesis and Properties

Abstract

In this study, metal complexes of the corresponding substituted phthalocyanines with magnesium and zinc, aluminum and erbium have been synthesized using the “nitrile” method by heating 4-(2,4,5-trichlorophenoxy)-5-nitrophthalonitrile with acetates and chlorides of some d- and f-metals. The influence of modifications to the peripheral environment of the central phthalocyanine core on spectral and other properties has been investigated. Demetalation of the magnesium complex has yielded the corresponding phthalocyanine ligand, whose acid-base properties have also been studied.
