Nucleophilic substitution in 4-bromo-5-nitrophthalodinitrile: XII. Synthesis and properties of 4-(1-benzotriazolyl)-, 4-nitro-5-(4-nonylphenoxy)phthalonitriles and the ligands based on them

Abstract

4-Nitro-and 4-(1-benzotriazolyl)-5-(4-nonylphenoxy)phthalonitriles were prepared by nucleophilic substitution of bromine and nitro group in 4-bromo-5-nitrophthalonitrile. Based on the latter the corresponding octa-substituted phthalocyanines were synthesized. The spectral properties of the prepared compounds were investigated.
