不对称卟啉及其锌配合物的制备及电化学研究

Preparation,spectroscopic and electrochemical property of an Unsymmetrical porphyrin and its Zn compound

合成了新型5-(4-吡嗪甲酰亚胺基)苯基-10,15,20-三苯基卟啉配体(H2P)及其锌配合物(ZnP),并通过质谱、元素分析、紫外-可见光谱、核磁共振氢谱、红外光谱等测试方法对其结构加以确认。同时还研究了配体和配合物的拉曼和荧光光谱的变化,并对其进行了电化学性质的研究。研究表明,配体和配合物的拉曼光谱及荧光光谱都有很大区别,卟啉的电化学性质不仅与周边取代基性质有关,还受其共轭体系的电子离域程度影响。

The new 5-（4-pyrazinoicaminophenyl）-10,15,20-triphenylporphyrin ligand（H2P） and its compound（ZnP） have been synthesized and characterized by elemental analyses,UV-Vis,IR and 1HNMR spectroscopies.The cyclic voltammetry,Raman spectra and fluorescence spectra of H2P and ZnP were investigated.The results showed that Raman spectra and fluorescence spectra of H2P was different from ZnP.The electrochemical properties of the porphyrin were influenced by the linked substitutent and electron conjugative effect of porphyrin.
