Abstract

© 2022 Informa UK Limited, trading as Taylor & Francis Group.Phthalonitrile (3) including 4-(4-fluorophenyl)-5-(4-methoxyphenyl)-4H-1,2,4-triazole-3-thio substituent and its peripherally tetra substituted metal-free (4), zinc(II) (5) and lead(II) (6) phthalocyanine derivatives were prepared and characterized by FTIR, mass, 1H-NMR and 13C-NMR spectroscopic data. All studied phthalocyanines had good solubility in common organic solvents and did not aggregate. The photophysical and photochemical behaviors of the phthalocyanine complexes (4–6) were examined in DMSO to determinate their PDT potential. Singlet oxygen, fluorescence and photodegradation quantum yields showed that zinc(II) phthalocyanine (5) has potential as Type II photosensitizer for PDT applications.
