Abstract: 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.
