Abstract :This work reports on the synthesis and characterization of gallium (III) phthalocyanines (4-6) which is non-peripherally tetra-substituted with anisole or thioanisole functional groups containing oxygen or sulfur bridge. Confirmation of the phthalocyanine structures performed with a combination of elemental analysis, FTIR, 1 H-NMR, UV-vis and MALDI-MS spectral data. Also, investigated and discussed the effects of non-peripherally tetra-substitution with different functional groups on the photochemical (Singlet oxygen quantum yields and photodegradation quantum yields) and photophysical properties (Fluorescence quantum yields and flouresans behavior). In every substituent, we obtained very similar singlet oxygen quantum yields as 0.64 for (4) , 0.56 for (5) and 0.65 for (6) suggesting its potential as photosensitizer in PDT treatment.Keywords : Phthalocyanine, Anisole, Thioanisole, Gallium, Photochemistry
