本文报道了5,10,15,20-四-(4-乙酰氧基苯)卟吩[T(4AOP)P]及其Cu、Zn、Fe、Co、Ni配合物的合成及其在CH_2Cl_2-0.1mol/1 TBAP体系中的循环伏安(CV)研究结果.CV实验表明:Cu~(2+)、Zn~(2+)、Ni~(2+)离子以稳定的+2价存在于T(4AOP)P中,电子转移反应在卟啉环上进行,而Fe~(3+)、Co~(2+)离子在氧化还原过程中发生价态变化。实验发现:不同金属卟啉在卟啉环上氧化还原顺序及其非均相电子转移反应速率常数与环上π电子云密度成规律性变化.
In this paper, the synthesis of 5,10,15,20-tetrakis (4-acetoxybenzene) porphine [T (4AOP) P] and its Cu, Zn, Fe, Co and Ni complexes has been reported. The results of cyclic voltammetry (CV) in 0.1 mol / 1 TBAP system showed that Cu 2+, Zn 2+ and Ni 2+ were present in stable +2 T (4AOP) P, the electron transfer reaction takes place on the porphyrin ring, while the valence change of Fe ~ (3 +) and Co ~ (2+) ions occurs during the redox process. The experimental results show that the order of the redox of different metalloporphyrins on the porphyrin ring and the rate constants of the heterogeneous electron transfer reaction have a regular change with the π electron cloud density on the ring.
