| 摘 要：金属卟啉是一类具有良好光敏性的大环芳香化合物。以cis-ortho-双捆扎的双弓型铜卟啉1-Cu至4-Cu为光催化剂，以平面铜卟啉TPP-Cu为参照，在异相和可见光下催化降解甲基橙。结果表明铜卟啉光催化性能与大环扭曲有正向相关性。采用动态紫外-可见吸收光谱手段跟踪大环扭曲对铜卟啉光催化性能的影响。 |

| Abstract：Metalloporphyrin is a macrocyclic conjugated aromatic compound with high performance of photosensitivity. The double-bowed copper porphyrins 1-Cu to 4-Cu cis-ortho-distrapped were used as photocatalysts to catalyze the degradation of methyl orange under visible light and heterogeneous condition, and the planar copper porphyrin TPP-Cu was used as a reference. The results showed a positive correlation between the photocatalytic performance of copper porphyrins and the macrocyclic distortion. The effect of macrocyclic distortion on the photocatalytic performance of copper porphyrins was tracked by means of dynamic UV-vis absorption spectroscopy. |
