摘　　要：本文用循环伏安法研究了1种新型生物模型化合物——二乙胺基尾式卟啉铁(meso-MDBPTPPFe(Ⅲ)Cl)的电化学行为及溶剂效应。结果表明:二乙胺基尾式卟啉铁中尾端叔胺起着调谐电位作用,稳定了低价态。溶剂不同,尾式卟啉铁各电对的半波电位也不同。实验发现,电对Fe(Ⅲ)/Fe(Ⅱ)和Fe(Ⅱ)/Fe(Ⅰ)的半波电位与溶剂的给电子数(DN数)成规律性变化。The electrochemical behavior and solvent effects of a new biological model compound——tailed porphyrin iron ( Ⅲ ) complex, meso-mono(o-(4-diethyl amino) butyramidophenyl) triphenyl porphyrin iron( Ⅲ) (meso-MDBPTPPFe( Ⅲ )Cl) was investigated by cyclic voltammetry. The experimental results demonstrate that (1) the terminal base in meso-MDBPTPPFeCl plays a part of potential modulation, and thus stabilizes the oxidation state of iron( Ⅱ ). (2) The half wave potential of each electronic pair for meso-MDBPTPPFe( Ⅲ)Cl is different with different solvents. Furthermore, the half wave potential of Fe( Ⅲ)/Fe( Ⅱ ) is almost directly proportional to the donor number of solvents, while that of Fe( Ⅱ )/Fe( Ⅰ ) is almost inversely proportional to the donor number of solvents.
