Synthesis of precursors of zinc and magnesium phthalocyaninates substituted by azochromophore fragments and their spectroscopic and luminescence properties
摘要
1-[4-(4-Methoxyphenyl)azo]naphthol was synthesized using diazotization and azo coupling reactions. The compound was used as a nucleophile to prepare 3- and 4-[(4-methoxyphenylazo)-4-naphthoxy]phthalonitriles. The corresponding metal complexes of phthalocyanines were synthesized by the template condensation of the resulting substituted phthalonitriles with zinc and magnesium acetates. The influence of the substituent position on the protonation processes and spectroscopic characteristics of metal phthalocyanines was determined. The luminescence properties of the synthesized metal complexes and photosensitization of singlet oxygen were studied.
