摘　　要：用紫外-可见吸收光谱和循环伏安法对四-(全氟苯基)-卟啉锌和四苯基卟啉锌的电子结构进行了对比研究,发现外围氟取代可以有效提高卟啉锌的氧化电位而不改变其电子跃迁能隙。通过四-(全氟苯基)-卟啉锌和四苯基卟啉锌的吸收性状、透射电镜下的微观形态和X射线衍射图样的对比分析,发现外围氟取代使分子的排列方式、晶体生长模式和晶格类型都明显改变。The electronic structures of zinc tetra-（perfluorophenyl）-porphyrin and zinc tetra-phenylporphyrin were studied by UV-visible spectroscopy and cyclic voltammetry. It was found that the peripheral fluoro-substitution of Zinc tetra-phenylporphyrin effectively enhanced the oxidative potential without changing its energy gap. With comparative analysis of UV-visible absorption features and X-ray diffraction patterns and direct observation of the morphology on transmit electron microscopy, the experimental results indicated that the peripheral substitution of zinc tetra-phenylporphyrin with fluorine atoms modified the mode of molecular packing, crystal growth and lattice type.
