The thermal oxidative decomposition of benzotriazolyl-substituted phthalocyanines and their copper complexes is investigated by means of thermogravimetric, elemental, and spectroscopic analysis. It is shown that the nature of peripheral substituents exerts the greatest effect on the thermal stability of the compounds.

4-(1-Benzotriazolyl)-5-(4-tritylphenoxy)phthalonitrile was synthesized by nucleophilic substitution of bromine and nitro group of 4-bromo-5-nitrophthalonitrile, and on its basis the corresponding octa-substituted phthalocyanines were obtained. Spectral properties of the synthesized compounds were investigated.
