摘 要：<正> Fifteen rare earth-tetraphenylporphyrin（RE-TPP）complexes were directly prepared by mixing equalmolar concentrations of RE（ClO4）3 and H2TPP in acetone media.The electrochemical behaviors of these com-plexes and the influence of dissolved oxygen were investigated by voltammetry.Althrough there are some differ-ence between the behaviors of light and heavy rare earth-porphyrins,the central RE ions of the all fifteen com-plexes were reduced from tervalent to divalent state,meanwhile the dissovled oxygen was reduced as superoxideion O-.which readily combined with the complex forming peroxide additive complex such as RE-TPP·O2-2.
