【摘要】 以吡咯和苯甲醛为原料,丙酸为溶剂采用Adler法合成了Meso-四苯基卟啉。金属化生成Meso-四苯基卟啉锌,磺化后得到Meso-四(对磺酸基苯基)卟啉锌。用红外光谱和紫外可见光谱对其主要基团进行了表征。研究了上述卟啉化合物及四磺酸卟啉锌与N3对纳米TiO2多孔膜电极的敏化及共敏化性质。结果发现:四磺酸卟啉锌具有较好的敏化效果,四磺酸卟啉锌与N3共敏化效果比单独的N3敏化时有很大程度的提高。更多还原

【Abstract】 Meso-tetraphenyl porphyrin was synthesized by Adler method starting from pyrrole and benzaldehyde with propionic acid as a single solvent. Meso-tetraphenyl porphyrin zinc(II) was synthesis by metalation of meso-tetraphenyl porphyrin with zinc acetate in DMF, and the meso-tetrakis (4- sulfonatophenyl) porphyrin zinc(II) was first prepared by sulfonationin in sulfuric acid. The title porphrins were characterized by IR and Uv-Vis spectrum. The sensitization of the TiO2 electrodes with these title prophyrins and co-sensitization of the TiO2 electrode with meso-tetrakis (4-sulfonatophenyl) porphyrin zinc(II) and N3 were studied. The results showed that meso-tetrakis (4-sulfonatophenyl) porphyrin zinc(II) showed the better photosensitivity, and dyes-cosensitization improved the performance of the dye-sensitized solar cell.更多还原
