英文摘要The use of nanoparticles as a potential building block for photosensitizers has recently become a focus of interest in the field of photocatalysis and photodynamic therapy. porphyrins and their derivatives are effective photosensitizers due to extended pi-conjugated electronic structure, high molar absorption from visible to near-infrared spectrum, and high singlet oxygen quantum yields as well as chemical versatility. in this paper, we report a synthesis of self-assembled porphyrin nanoparticle photosensitizers using zinc meso-tetra(4-pyridyl)porphyrin (zntpyp) through a confined noncovalent self-assembly process. scanning electron microscopy reveals formation of monodisperse cubic nanoparticles. uv-vis characterizations reveal that optical absorption of the nanoparticles exhibits a red shift due to noncovalent self-assembly of porphyrins, which not only effectively increase intensity of light absorption but also extend light absorption broadly covering visible light for enhanced photodynamic therapy. electron spin-resonance spectroscopy (esr) studies show the resultant porphyrin nanoparticles release a high yield of singlet oxygen. nitric oxide (no) coordinates to central metal zn ions to form stabilized zntpyp@no nanoparticles. we show that under light irradiation zntpyp@no nanoparticles release highly reactive peroxynitrite molecules that exhibit enhanced antibacterial photodynamic therapy (apdt) activity. the ease of the synthesis of self-assembled porphyrin nanoparticles and light triggered release of highly reactive moieties represent a completely different photosensitizer system for apdt application.
