The peripheral and non-peripheral 2H-benzotriazole substituted phthalocyanines: Synthesis, characterization, photophysical and photochemical studies of zinc derivatives.

In this study, the novel 3-(1H-benzo[d][1,2,3]triazol-1-yl)methoxy substituted novel phthalonitrile compounds (2 and 6) were synthesized. Their non-peripheral and peripheral zinc (II) (3 and 7), manganese (III) (4 and 8) and copper (II) (5 and 9) phthalocyanine complexes were synthesized for the first time. These novel compounds were characterized by elemental analysis and different spectroscopic techniques such as FT-IR, UV-Vis, 1H NMR, 13C NMR and MALDI-TOF mass. Also, photochemical and photophysical properties of non-peripheral and peripheral substituted zinc (II) phthalocyanines (3 and 7) were investigated for determination of photodynamic therapy applications of these phthalocyanines.
