Abstract

In this study, a new metal oxide NP/MPc derivative composite as efficient photosensitizer for photodynamic therapy of cancer and photocatalytic activities is developed. The ZnPc(COOH)4/MgO composite consists of the synthesized water soluble tetra-carboxy zinc phthalocyanine derivative and magnesium oxide nanoparticles prepared with different precipitating agents. The ZnPc(COOH)4/MgO composites were investigated by UV-Vis spectroscopy and fluorescence spectrophotometry. The absorption and emission spectra of the self-assembled ZnPc(COOH)4/MgO composite highlight the Stokes shift between them, which is near 119 nm. The composites also exhibited room-temperature phosphorescence with an average triplet state lifetime of 5.01 μs and a quantum yield of 10.63%.
