In this study, novel peripherally ferulic acid tetra-substituted Zn(II) phthalocyanine was synthesized for the first time. The synthesized phthalocyanine was characterized by elemental analysis, Infrared spectroscopy, UV-vis spectroscopy, 1 H-NMR spectroscopy and MALDI-TOF MS techniques. The photophysical, photochemical and aggregation properties of this phthalocyanine were also investigated in DMSO and DMF solvents. The aggregation studies showed that the synthesized Zn(II) phthalocyanine has not aggregated in DMSO and DMF. Fluorescence quantum yield ( Φ F : 0.23 in DMSO and 0.17 in DMF), singlet oxygen quantum yield ( Φ ∆ :0.57 in DMSO and 0.45 in DMF) and photodegradation quantum yield ( Φ d :1.08x10 -5 in DMSO and 4.48x10 -5 in DMF) were also determined. These results show that the synthesized phthalocyanine has potential use in photodynamic therapy.
