Nucleophilic substitution in 4-bromo-5-nitrophthalodinitrile: XVIII. Synthesis and spectral properties of octasubstituted zinc phthhalocyanines with cyclohexylphenol moieties

Abstract

Using 4-bromo-5-nitro- and 4,5-dichlorophthalonitriles, substituted phthalonitriles containing a fragment of 2-cyclohexylphenol and nitro- or 1-benzotriazolyl groups, as well as phthalonitrile containing two 2-cyclohexylphenoxy groups, were synthesized. Tetramerization of these precursors with zinc acetate hexahydrate gave the corresponding octa-substituted zinc phthalocyanines. Their spectral properties were studied.
