摘　　要：对系列取代金属(铁、锰、钴、铜、锌)卟啉化合物的紫外光谱、红外光谱、远红外光谱进行了详尽的测试和分析,揭示了不同结构金属卟啉的光谱规律,从理论上分析了形成光谱规律的原因。针对目前氯化铁卟啉轴向Fe—Cl键远红外表征的报道结果不一致性,采用理论分析与实验测定相结合的方法,探索了氯化铁卟啉中Fe—Cl键远红外吸收规律。研究结果表明:Fe—Cl键的振动吸收频率不是固定不变的,而是与卟啉环的结构有关,且和Fe—Cl的键长呈线性关系。A full IR, UV-Vis, FIR, spectroscopic analysis on substituted porphyrin iron, manganese, cobalt, copper and Zinc complexes was performed, and the spectroscopic patterns were found for the metalloporphyrin compounds with various structures. Base on molecular structures theory, the reasons for the spectroscopic patterns were discussed deeply. Considering the inconsistency of the far-infrared spectra of the Fe-Cl axial bonds in chloro-iron tetraphenylporphyrins reported in the literature. Their far-infrared absorptions were investigated by using both theoretical analysis and experimental determination, and the results showing that their vibrational frequencies of the Fe-Cl bonds in different substitution chloro-iron tetraphenylporphyrins were associated with their structures, and were linearly related to the length of Fe-Cl bonds.
