5,10,15,20-四(对-十四酰亚胺基苯基)卟啉及其锰、锌配合物的合成及性质

合成了5,10,15,20-四(对-十四酰亚胺基苯基)卟啉配体(TMPPH2)及其锰、锌金属配合物(TMPPMnCl, TMPPZn), 并通过紫外-可见光谱、红外光谱、核磁共振氢谱、元素分析等技术对化合物的结构加以确认, 研究了配体和配合物的拉曼光谱、光电子能谱和荧光光谱的变化及电化学性质. 结果表明, 配体和配合物的紫外光谱、红外光谱、拉曼光谱、荧光光谱及光电子能谱都有很大区别, 锰配合物的循环伏安曲线与配体和锌配合物不同, 除了卟啉环发生氧化还原外, 还发生了金属离子的氧化还原反应.

Preparation and Properties of 5,10,15,20-Tetra(4-myristylimidophenyl)Porphyrin and Its Zn and Mn Complexes

A new porphyrin 5,10,15,20-tetra(4-myristylimidophenyl)porphyrin(TMPPH2) and its complexes TMPPMnCl and TMPPZn were synthesized and their structures were confirmed by means of elemental analyses,UV-Vis spectra,infrared spectra and 1H NMR spectra.Raman spectra,fluorescence spectra and X-ray photoelectron spectroscopy spectra of the porphyrin and its complexes were investigated.The electrochemistry of the ligand and the complexes was also studied.The results show that there are much difference between the ligand and the complexes in the UV-Vis spectra,infrared spectra,Raman spectra,fluorescence spectra and XPS spectra.The cyclic voltammetry of TMPPMnCl is different from those of the ligand and TMPPZn,which showed not only the redox of the porphyrin ring,but also the redox of the metal ion Mn3 .
