4-[4-Bromo-2-(2-phenyldiazenyl)phenoxy]phthalonitrile and related magnesium and zinc phthalocyanines: synthesis and properties.

4-[4-Bromo-2-(2-phenyldiazenyl)phenoxy]phthalonitrile was obtained by the reaction of 4-nitrophthalonitrile and sodium 4-bromo-2-(2-phenyldiazenyl)phenolate. Magnesium and zinc phthalocyaninates were synthesized by the template condensation of the corresponding metals with phthalonitrile. The luminescence properties and photosensitization of singlet oxygen for the synthesized complexes were studied. [ABSTRACT FROM AUTHOR]
