Erratum to: “Nucleophilic Substitution in 4-Bromo-5-nitrophthalodinitrile: XI. Preparation, Properties, and Prediction of Mesomorphism in Mixed-Substituted Phthalocyanines Containing Aryloxy and Benzotriazole Fragments”

Abstract

Stepwise nucleophilic substitution of bromine and nitro group in 4-bromo-5-nitrophthalodinitrile has led to a series of phthalonitriles containing benzotriazole and aryloxy fragments; basing on them, the mixed-substituted phthalocyanines have been prepared. The spectral properties of products have been studied. According to simulation of columnar mesomorphism only one of the products is not capable of mesomorphism characteristic of discotic mesogens; the result has been confirmed with the experiment.
