Synthesis and Properties of Tetra(4-tert-butyl-5-phenylsulfanyl)phthalocyanines and Their Derivatives

The methods of synthesis of 4-tert-butyl-5-sulfanylphenyl-and 4-tert-butyl-5-(4'-carboxyphenylsulfanyl) phthalonitriles have been developed and on their basis the corresponding octa-substituted phthalocyanines have been prepared. The effect of the structure of the above phthalocyanine derivatives on their electronic absorption spectra and parameters of thermal degradation in the presence of air oxygen were studied.

Low symmetrical phthalocyanines having spectroscopic and electrochemical properties characteristic of unexpected accidental S1 state degeneracy and non-planar distortions

Low-symmetrical phthalocyanines (Pcs) 2-5 prepared by mixed condensation of tetraphenylphthalonitrile and 4-phenylthiophthalonitrile in the presence of a copper salt, show spectroscopic, electrochemical, and molecular model indications which suggest varying degrees of non-planar distortions of the Pc plane and unexpected S1 state degeneracy.
