Özet
This study is focused on the photophysical and photochemical properties of silicon and zinc phthalocyanines. Fluorinated pyrazoline-linked axial silicon phthalocyanine (HY-SiPc), peripheral zinc phthalocyanine (HY-ZnPcβ), and non-peripheral zinc phthalocyanine (HY-ZnPcα) were synthesized and their structural characterizations were carried out by known Mass, NMR, UV–Vis, and FT-IR techniques. The concentration (in DMSO) and solvent effects (THF, DMSO, CHCl3, DMF, and EtOAc) of the phthalocyanine compounds were studied. The effects of the metal ion in the ring cavity (Zn2+ or Si4+) and the binding positions of the substituted group on photodynamic therapy properties were comparatively investigated. The photochemical and photophysical measurements were investigated in dimethylsulfoxide (DMSO). Examining the results, fluorinated pyrazoline-linked axial silicon phthalocyanine (HY-SiPc) showed the highest singlet oxygen production in this solvent and can be candidate a photosensitizer for PDT.
